Llanelli Naturalists Newsletter - Summer 1992
Richard Pryce

More records were made during 1991 than in the previous few years. Not only did George Hutchinson (GH), as has become usual, provide a pile of record cards nearly two inches thick (not to mention a lever-arch file full of A4 sheets detailing his, and others', determinations of specimens accumulated in NMW since the inception of the project in 1981) but lan Moraan (IKM) returned to concentrate on floral recording, a diversion from his beloved invertebrates, at least for this season, and included some Important new botanical records and rediscoveries. In fact lan produced so large a volume of material that he undertook to write his own report which is reproduced below in toto. I will therefore concentrate on the records submitted by George and the other field-workers but inevitably there is some degree of overlap.

New Vlce-County Records

Several plants of Papaver lecoqii (Yellow-juiced Poppy) growing on a disturbed, burnt area of limestone cliff at Dolwen Point, Pendine, SN233078, were discovered by lKM at the end of May growing with Carduus acanthoides (Welted Thistle) whilst Epilobium ciliatum x E.tetragonum (a hybrid willowherb) was a first Welsh record from below the village bridge at Pentrecwrt, SN390386, (GH, det. G.D.Kitchener & B. Wurzell).

Lemna minuscula (a species of duckweed) was reported from two sites by lKM: the 1st and 2nd vcrs and also the 3rd and 4th Welsh records: in a broad ditch alongside Ffordd-y-Wagen, Pwll, SN462012, in "superabundance" and in flooded areas of a reed swamp east of Burry Port, SN458010, both det. lKM. cont. GH & A.Orange (AO). Myriophyllum aquaticum (a species of water-milfoil) was recorded at Dafen Pond, SN531015, (IKM, conf.GH) in the company of Chara connivens (a stonewort) (IKM, det.A0), not only a ncr but also new to Wales and only the sixth mainland British vc record.

A specimen of Pteridium aquilinum (Bracken) collected by A.E.Wade in 1930 from Ferryside was determined as subsp. atlanticum by C.N.Page in March 1991.

P.J.O. Trist (PJOT), one of the referees for Gramineae, has recently determined some critical grasses from Carms. including the following: Festuca rubra subsp. rubra x Vulpia myuros (a hybrid between Red Fescue and Rat's-tail Fescue) collected by GH & RDP from a sandy area adjoining the beach southwest of the Burry Port power station, SN449001, in May 1989: Bromus hordeaceus subsp. ferronii (Least Soft-brome) collected by RDP during a Llanelli Naturalists' field meeting from a dry bank below Sir John's Hill. Lauaharne. SN299097, on 17 June 1984; Bromus commutatus var. oubens (Meadow Brome) collected by GH from a road verge 1.5km southeast of Ferryside, SN382094, in June 1986 and Bromus x pseudothominei (Lesser Soft-brome) collected by RDP from waste around at the roadside near the Butcher's Arms, Pembrey, SN419021, in c1980.

Other ncr grasses were the fescues Festuca rubra subsp.juncea collected by GH from the seashore southwest of Llanelli railway station, SS5098, in June 1990 and Festuca arenaria from shingle at the foot of a calcareous cliff near Llansteffan (SN30), collected by Mrs.I.M.Vaughan in June 1967 (ciet.A.L.A1-Bermani & Prof.C.A.Stace). Echinochloa utilis (a species of Cockspur grass) was a ncr and only the 2nd vc for Wales, discovered by IKM on river shingle of the Afon Lliedi in Llanelli, SN509006, (det. GH) growing with an abundance of casual species including Lepidium sativum (Garden Cress), the 2nd vcr.

Several determinations by either GH or the respective referees resulted in ncrs from material of more non-native species reposited in NMW. Aconitum x cammarum (a monkshood) was a garden escape along Llangunnor Road, Carmarthen, SN422196, (GH. 3rd Welsh record) and Oenothera missouriensis (a species of evening primrose) was a weed in Mrs. Annie-Mary Pell's garden (AMP, det. GH). Tropaeolum majus (Nasturtium), another escape, was growing by rubble tipped at St. John's Hill, Laugharne, SN302104, (GH) and also at Laugharne, Hebe x franciscana was recorded during the BSBl meeting growing rampantly on the cliff above Dylan Thomas Boathouse, SN306110 but was also apparently self-sown on nearby walls (Pryce. 1992). Erigeron glaucus, a Darden throw-out on a road embankment at Pwll was recorded by GH & RDP in August (det. GH, conf. E.J. Clements). Pseudofumaria alba (= Corydalis ochroleuca) was determined by D.McClintock from a specimen collected at Gelli Aur, SN5920, by Denys Smith (DS) in April 1988 and Cy mballaria pallida (Greater Ivy-leaved Toadflax) was collected by RDP in July 1982 at Pontyberem Churchyard, SN497104, and determined by GH, 1991.

Second And Thlrd Vice-County Records

Carex punctata (Dotted Sedge) was discovered at both its second and third vc sites in 1991. One plant at SN301073 and several at SN291077 were seen growing in dune slacks amongst Salix repens (Creeping Willow) at the Proof and Experimental Establishment. Pendine, during the Conservation Group meeting on 2nd July (John Rees (JR): GH & RDP. conf. A.O. Chater (AOC)). At the same site. SN3007, the Carex sp. collected by JR & RDP in June 1989 was determined by AOC as C. acuta (Slender Tufted-sedge), the third vcr. Still at Pendine Burrows. Bidens frondosa (Beggarticks) was determined by GH in 1991 from material collected in 1956 by Vera Gordon at the Witchett Pool. SN2807. This is the 2nd vcr although predating the first record (from Bynea. Morgan (1987)) by thirty years.

The 2nd native site in the vc of Helianthemum nummularium (Common Rockrose) was recorded in 1989 by Dawn Grey who found it growing amongst limestone outcrops and grassland at Dan-y-Cincoed, Llandyfan. SN647176. Koeleria gracilis (Crested Hair-grass) was also growing nearby, the 2nd extant record (comm. IKM, 1991).

A clump of Coronilla varia (Crown Vetch) in full flower recorded by GH on a railway-side wall east of Llanelli Station, SS508993. was the 2nd vcr and first since 1969. IKM recorded the 2nd record of Valerianella carinata (Keel-fruited Cornsalad) at Furnace, Llanelli, SN503012, where a few plants were growing as weeds in a lane.

The 2nd record of the whitebeam Sorbus croceocarpa was determined by P.J.M. Nethercott from material collected by IKM from the four trees in open oak woodland near Llety-yr-Ychen Fawr, Burry Port, SN455015.

The 2nd and 3rd vcrs of the hybrid shield-fern, Polystichum x bicknellii (P.setiferum x P.aculeatum) were determined by GH, his material now in NMW: from a hedgebank at Tavernspite, SN179123, collected in 1987 and from a hedgebank near Trapp, SN654183, collected in 1988.

Azolla filicoides (Water-fern) has been recorded by Trevor Crosby (TSC) in varying amounts in recent years in the pond at Gelli-deg, SN423105 (2nd vcr) and the species was also recorded in 1991 in the inflowing stream to the new lake in Sandy Water Park, SN492006, (3rd vcr) (GH). It is remarkable how quickly new water bodies can be colonised: in addition to the Azolla at this site, GH & IKM recorded Ceratophyllum demersum (Rigid Hornwort) (another 2nd vcr), Zannichellia palustris (Horned Pondweed), Elodea nuttallii (Nuttall's Waterweed) (first record substantiated by referee). Potamogeton crispus (Curled Pondweed) and P. obtusifolius (Blunt-leaved Pondweed) (2nd vcr) (the last three det.C.D.Preston). CDP also determined Potamooeton perfoliatus (Perfoliate Pondweed) collected by GH from Dafen Pond (3rd vcr) which also held populations of P.crispus and P.natans (Broad-leaved Pondweed) (GH). The new pond near Kidwelly Quay, 5N401061, also held P.drispus together with Nymphaea alba (White Water-lily) and the stonewort Chara vulgaris var.londibracteata (det.A0) (ncr). P.crispus was also reported by John Savidge in another very recently constructed pond on restored opencast land at Bryngwyn Farm, Penygroes, SN588143. Other P.crispus records were in ponds at Pengay Farm, SN373085; Glantaf Farm, SN368088, (with Ranunculus peltatus (Pond Water-crowfoot)) (both GH) and Pistyll Quarry Pond, Llandybie, SN624167, where it was growing with Elodea nuttallii (ACC).

2nd and 3rd vcrs of of the Soft-brome. Bromus hordeaceus subsp.thominei were determined bt P3OT from material collected in 1982 at Laugharne Burrows, SN20T, and in 1989 from dunes near the Undercliff Hotel, Ferryside, SN368108 (both GH).

Other 2nd vcrs attributed to GH were: Hordeum jubatum (Foxtail Barley), recorded near Kidwelly Quay, SN397061, during a session primarily searching for Salicornia (Glasswort); Limnanthes douglasii (Poached-egg Plant) recorded spreading away from a garden at Nant Farm, Llangunnor, SN436196; hychnis coronaria (Rose Campion) and Salvia verticillata (Whorled Clary) found growing on the former railway sidings at Morfa, Llanelli, S8516991, and Lobelia erinus (garden Lobelia) on a shingle bank in the River Teifi near Pentrecwrt, SN392395, which was also only the third Welsh record. From material he collected in 1990 at Aberglasney, SN580221. GH also determined Cirsium eriophorum (Woolly Thistle), the 2nd vcr and first since the mid 1850s, which was growing with Carduus acanthoides.

Rediscoveries

There were several records of species not seen for many years. Probably most notable was Barry Stewart's Sison amomum (Stone Parsley) growing beside a path at Penclacwydd SS530986, the first record since Motley's of c1850. Also new at Penclacwydd was Barry•s Myosoton aquaticum (Water Chickweed) (comm.IKM). Lemna gibba (Fat Duckweed) was found growing abundantly in a ditch at Glanrhyd Farm, Pembrey, SN406043, by IKM, the first sighting since Motley's unlocalized record of c1840. IKM also discovered the species at three other sites in the vc. Misopates orontium (Lesser Snapdragon) was discovered as a weed In the Bigyn Hill allotments, Llanelli, 50509998. by IKM, last recorded in the vc by Webb in 1944. Rubus saxat)Ais (Stone Bramble) was also rediscovered by 1KM above Pont Clydach on Mynydd Du on a wet, rocky streamside at SN743189, the first record since D.P.M.Guile s of 1951 at the same location and another upland species. Carex montana (Soft-leaved Sedge), was refound, again by IKM, at Carreg-yr-Ogof, last seen in 1976 by S.B. Evans and M.E. Massey. Another lKM record was that of Polygonum minus (Small Water-pepper) at the Bishop's Pond, Abergwili, SN443209, which was also the 2nd vcr (det.GH & R.G. Ellis).

Critical Taxa

Nine Hieracium (hawkweed) specimens in NMW were provisionally determined in 1991 by Jim Bevan as H. strumosum, all from the northeast of the vc. GH now has the self-taught expertise to identify the microspecies of E.officinalis agg. (eyebright) and has provisionally determined 96 Carms. specimens accumulated in NMW. 24 additional specimens have been with the referee, Alan Silverside, for some time and their identifications are awaited.

Carum and Salicornia

There were eleven new tetrad records for Carum verticillatum (Whorled Caraway) and, with one exception, all were from the northeastern quarter of the vc. The species remains undiscovered in several partial 10km squares on the periphery of the vc, these being SN02, SN10, SN11, SN24, SN30, SN34, SS49, SS59, SN65, SN75 and SN82. Suitable habitats are probably absent from most of these squares but it is likely that the plant occurs in the northeastern parts of SN11 and maybe in SN30. lt should also be present in SN82.

GH has added several new Salicornia (glasswort) records in 1991 whilst, from material collected in 1990, D.H.Dalby has confirmed or determined S.europaea from Cwmcelyn, SN318118, (GH & RDP); near Yspitty, SS558980, (GH & RDP); near Tir Morfa, SS532978, (lKM) and Llangennech, SN565010, (IKM); and S. fraqilis from Morfa Uchaf, SN368112, (GH); near Penallt, SN386068, (GH) and near Pant-yr-athro, SN371132, (GH & RDP). For distribution maps of other Salicornia records see Hutchinson (1991). S.pusilla has proved to be far more widespread in the vc than previously thought. It is now known from nine tetrads.

Other Notable Records

Orobanche rapum-genistae (Greater Broomrape) was recorded at a new site in 1990 and monitored in 1991 by Dai Stacey who reported c30 plants growing on Cytisus scoparius (Broom) in scrubby, cliff grassland at Wharley Point, SN339094. He also noted c20 plants growing on Ulex (gorse) at the Cwmcelyn colony, SN316125, in 1990 and 1991. James and Mary lliff (J&MI) refound O. rapum-oenistae opposite the entrance to Maescadog Farm, SN688394 and Dorothy Brookman and Mike Smith (DB&MS) reported that the previously known extensive colony east of Llandovery, SN779344, extended onto the neighbouring tetrad at SN780344. A colony of Orobanche minor (Common a Broomrape) was discovered by GH in SN30T in May and from the same tetrad he also recorded Geranium columbinum (Long-stalked Crane s-bill). G. pyrenaicum (Hedgerow Crane's-bill), Nasturtium microphyllum (Narrow-fruited Water-cress) and the planted hybrid willow, Salix x sepulcralis nothovar. chrysocoma.

There were several records of Epipactis helleborine (Broad-leaved Helleborine) during the year: at Newfoundland Farm, SN6228; Rhandirmwyn. SN74W; near Cefn Rickett, SN73T; Cwm Clyd, Myddfai, SN73V; a rough field near Cwm-Rhuddan, SN766327 (all J&MI); one plant by the entrance to the upper track to Esgair-isaf, SN379232 (TSC) and three spikes on the roadside near Llanfihangel Cilfagen Church, SN575243, (DS).

Twelve spikes of Platanthera chlorantha (Greater Butterfly Orchid) were reported in 1991 by Peter Wilde from the previously known site near Gwernogle in SN53N. IKM reports, however, that an unimproved pasture found in 1991 supporting P. chloran_tha together with abundant Dactylorhiza maculata subsp. ericetorum (Heath Spotted - orchid) and Sanguisorba officinalis (Great Burnet) near Felindre, SN696306, has been completely destroyed by ploughing and re-seeding after he wrote to the farmer telling him of its floral interest.

Two plants of Listera ovata (Common Twayblade) were found by GH growing on top of a laneside bank north of Pendine. SN239103. His records also included: Ornithopus perpusillus (Bird's-foot) from Wharley Point. SN339094; Myrrhis odorata (Sweet Cicely) in Cwmduad village, SN376310; Fumaria capreolata (White-Ramping-fumitory) in a hedge at Draenoa Farm. Graig, Burry Port, SN439018 and Coronopus squamatus (Swine-cress) from south of St-John's Hill, Laugharne, SN304096 (lKM also found this species on a footpath at Bryn, SN556005). Also, GH determined the hybrid avens, Geum x intermedium, from material he collected at Ffairfach. SN613192, in 1987 and from woodland on the Carms. bank of the River Eastern Cleddau. west of Clynderwen. SN085187.

A substantial population of Parentucellia viscosa (Yellow Bartsia) was found by RDP growing in damp disturbed ground at Garnant opencast site, SN683131, the first vcr away from the coast. Hyocyamus niger (Henbane) was recorded for the first time since 1977 by Jane Kelsall growing very near to its old site in an open area at the edge of Pembrey Forest, SN392033, (Pryce. 1991: note revised grid ref.for Hyocyamus).

The polypody fern, Polypodium cambricum, was recorded by members of the 8S8I party who visited Laugharne Castle, 5N301107, in June (Pryce, 1992). The 'hybrid buckler-fern, Dryopteris x deweveri (D.carthusiana x D. dilatata), was recorded in 1991 to the northeast of Ffynnon-newydd, SN428276, (IKM. field record) and material collected near Llanddewi-Velfrey, SN14ll79, by GH in 1986 also proved to be this hybrid (det. C.R.Frazer-Jenkins). The form of Hard Shield-fern Polystichum aculeatum forma cambricum, was determined by GH from material collected by RDP in 1979 on limestone waste at Blaen-y-Van Quarry, SN454115 and one plant of the clubmoss Huperzia selaao was found growing on the face of an old limestone quarry at Clogau Bach, Mynydd-Du, SN718193, out of reach of even the most agile sheep (IKM & RDP).

Trisetum flavescens (Yellow Oat-grass) was recorded from four new sites, namely Mynydd Llanybydder, SN526397, (DB&MS); on the edge of a forestry Plantation at Aberhenwen, SN834290, (H.J.Killick (HJK)): around a memorial seat at Scotts Bay, Llansteffan. SN349099 (GH) and on a roadside verge at Mynydd Floyn. SN603303, (TSC). TSC also visited an abandoned chapelyard at Capel Iwan. SN294362. which had Lilium pyrenaicum (Pyrenean Lily) and Polygonatum multiflorum (Solomon's-seal) whilst he also recorded Primula veris (Cowslip) growing abundantly in Pengwern Bica Chapelyard. SN23T, together with Rhinanthus minor (Yellow-rattle).

Montia sibirica (Pink Purslane) continues its relentless spread down the Tywi valley with IKM's record from broad-leaved woodland on the river cliff below Pont-ar-Ffynnant picnic site, SN507201. How long will it take to reach SN42?

HJK's records included Vicia orobus (Wood Bitter-vetch) from a rocky slope near Waun Ddu Mire SSSI, SN818297; Myriophyllum alterniflorum (Alternate Water-milfoil) from a flush at Tomen-y-Rhos, SN807297; Genista tinctoria (Dyer's Greenweed), SN825296, and Equisetum sylvaticum (Wood Horsetail), SN827293, from north of the Usk Reservoir and Eleocharis quinquiflora (Few-flowered Spike-rush) by the Usk Reservoir at SN810280.

Whitehill Down was the venue for a BSBI Field Meeting in June. Those eminent botanists in attendance made several new records at this very rich and diverse grassland site. Included were Carex pallescens (Pale Sedge) and Lysimachia vulgaris (Common Loosestrife) (both det. AOC) and two Euphrasia (eyebright) species provisionally determined by GH (Pryce, 1992).

J&MI rediscovered Verbascum lychnitis (White Mullein) from an old mine site in Rhandirmwyn, SN781435, last seen by Mrs.Vaughan in the late 1960s. From the same tetrad they also recorded abundant Ornithopus perpusillus (SN798427), Primula veris, Campanula trachelium (Nettle - leaved Bellflower), Wahlenbergia hederacea (Ivy-leaved Bellflower) and Silene vulgaris subsp. maritima (Sea Campion). The latter was also present. in SN74X and growing nearby was Cirsium dissectum (Meadow Thistle).

A hedgebank 2km south-southwest of Cwmann, SN576455, supported Filipendula vulgaris (Dropwort), normally a plant associated with graveyards in Carms and only the 2nd vcr away from such (TSC). Veronica agrestis (Green Field-speedwell) was recorded at two sites by HJK & Pauline Goodhind (PG): in Llansawel, SN619362, (with Lepidium heterophyllum (Smith's Pepperwort), the hybrid ragwort Senecio x ostenfeldii and Vulpia bromoides (Squirreltail Fescue) in the vicinity) and at Pystyllgwyn, north of Llansawel. SN620379. Conium maculatum (Hemlock) was discovered on a roadside near Bolahaul, Talley, SN6532, by David Humphreys & PG whilst Kate Medcalf noted Poa compressa (Flattened Meadow-grass) in restored opencast land near Penygroes, SN585140. Frank Webb reported frequent plants of Sanguisorba minor subsp. muricata (= S.polyqamum) (Fodder Burnet) growing on hedgebanks constructed about five years ago on the former Lamberts Colliery opencast site at Carway, SN455067: this species was a consituent of the seed-mix used at that time (together with Medicago sativa (Lucerne)) and has also been seen in similar situations at Capel Hendre, SN598116; Saron, SN607129 and Llandybie, SN610145 (all RDP)

Newly Discovered &Quot;Good Sites&Quot;

Drosera intermedia (Oblong-leaved Sundew) was discovered by IKM at its fourth site in the vc, at Cors Helyg, Rhosaman, SN740136, a very species-rich series of flushes covering a very small area, possibly under threat of future opencast mining.

A superb valley mire at the head of the Nant-y-Garth east of Garth Farm. Ffarmers. SN676451 to SN680451, was stumbled upon by RDP during the Lampeter meeting. Locally very abundant on the stream-sides was Wahlenbergia hederacea together with Hypericum elodes (Bog St. Jonn s-wort) growing amongst dominant Sphagnum carpets in the flushed valley bottom. Carum was locally abundant and Marsh Fritillary butterflies were present.

Viola lutea (Mountain Pansy) was present in several fine populations at the summit of Garth Crags, SN679458 & SN680458 and was also found at Bryn-Nicol: locally frequent in sheep-cropped acid grassland at SN821443. A few plants were also seen on a laneside bank at SN819427 (RDP & GH).

At Maudsland, SN335344, in an area of acid grassland remaining where forestry plantings had failed. GH & RDP recorded two plants of Osmunda regal_is (Royal Fern) and three plants of Dryopteris carthusiana (Narrow-leaved Buckler-fern) growing amongst dominant, tussocky Molinia caerulea (Purple Moor-grass) with encroaching willow scrub. At SN330343 one plant of Dryopteris affinis ssp. cambrensis_ (a subspecies of Scaly Male-fern) was found by RDP (det. GH) growing in Calluna-Erica (heather) dwarf-shrub heath by an old quarry.

Species-rich moorland and upland flushed sites were noted by several recorders, for instance near Blue well Farm, Llanfihangel Rhos-y-Corn, SN506347, (Isolepis setaceus (8ristle Club-rush), Scutellaria minor (Lesser Scullcap), Serratula tinctoria (Saw-wort)), at Mynydd eg SN511375, and at Mynydd Llanybydder, SN526397, (Hypericum elodes. Drosera rotundifolia (Round-leaved Sundew), Potamogeton polygonifolius Pondweed), Wahlenberdia hederacea) (all HJK,DB & MS) and Mynydd Figyn. SN6330, (Car-ex hostiana (Tawney Sedge), Narthecium ossifraqum (Bog Asphodel) and Eleocharis quincluiflora) (TSC).

J&Ml produced an impressive species list from Carn n Nant-yr-Ast, SN743. principally an extensive area of Molinia dominated moorland, which included Dryopteris carthusiana (from both SN735487 and SN731493), Carex curta (White Sedge), C.hostiana, C.rostrata (Bottle Sedge), Finquicula vulgaris (Common Butterwort) and Phinanthus minor together with putative hybrid sedges C.x involuta (C.vesicaria x C.rostrata) and C.x fulva (C.demissa x C.hostiana). Another upland site investigated by J&MI was the Ochr-y-Fforest ridge, cSN763377, where Geranium ousillum, (Small-flowered Crane's-bill) Veronica adrestis and Ornithopus perpusillus were seen. Further searching of this and similar well drained, gravelly hill-tops may be rewarded in early season by such species as Moenchia erecta (Upright Chickweed).

A wet pasture at Banc Pystyllgwyn, SN622386, had for example, Carum. Alchemilla glabra (a Lady's Mantle), Anagallis tenella (Bog Pimpernel) and Narthecium (HJK & PG) and a marshy field at Ael-y-Bryn, Brechfa, SN533303, was seen by TSC to have Genista anglica (Petty Whin) present with Carum, Calluna (Heather). Erica tetralix (Cross-leaved Heath), Succisa pratensis (Devil's-bit), Narthecium etc. J&MI recorded Carum, Cirsium dissectum and Potentilla palustris (Marsh Cinaufoill at Felin Newydd. SN63U and at Llwyn-y-Berllan, SN758374. they found Carum and Cirsium dissectum accompanied by Veronica scutellata (Marsh Speedwell) and Scutellaria

As always, i am very grate'ul to all recorders who have submitted recdrds. most of whom have been credited above. Special mention must be made of James and Mary Iliff who continue not only Just to "tick-off" those species seen but also meticulously describe all their excursions giving details of habitats encountered, routes taken and any other relevant information. George Hutchinson and Ian Morgan also provide a wealth of extra detail for notable records including population forms and "further information". George has also been responsible for a great many laboratory determinations of material accumulated over the years at NMW and several critical records are the result of his labours. Thanks also to the referees who have also been consulted during the year. Finally I must thank Stephen Coker, the author of the Biorecs computer software which I am now using, whom I have put under some pressure to get everything up and running in readiness to be able to produce this report.
