THE FLORA OF THE WORMS HEAD 91 



and more exposed ground more than does H. Chanicecistus. Poly- 

 gala vulgaris ; Silene maritima becomes gradually more frequent 

 seawards until it occupies nearly the whole ground. Cerastium 

 tetrandrum, viscosum, vulgatum, Stellaria apetala, Arenaria ser- 

 pyllifolia ; Sagina maritima, in many forms and sizes, not assign- 

 able to any named in the London Catalogue, I believe, though 

 var. densa occurs on Burry Holm, four miles away. <S'. pro- 

 cumbens, Sj^ergularia marginata. Malva sylvestris, several plants 

 in two or three spots on the middle " island " ; and occurring on 

 other very out-of-the-way cliff-tops, e. g. at Mewslade Bay, near 

 Port Eynon, as well as at Southerndown. As native, no doubt, 

 as the Lavatera which accompanies it, on inaccessible rock faces 

 in Mewslade Bay. Limmi catharticum, Geranmm sanguineum, 

 molle, Bohertianum, Erodium cicutarium, and E. maritiiimvi, the 

 latter in great quantity, sometimes forming an exclusive mat of 

 vegetation yards across. Ulex europcBUS, Anthyllis Vulneraria, 

 Lotus corniculatus, Primus spinosa, Buhus ccesius, Potentilla 

 sterilis, Poterium Sanguisorha, Sedum acre, Conopodium majus, 

 Crithmum maritimum; Heracleum only on the steep side of the 

 large " island," in one long clearly defined line, where it had the 

 protection and support of other tallish vegetation. Daucus Carota, 

 but not D. gummifer, which occurs in typical form at Nash Point. 

 Hedera, near the Heracleum, Asper^da cynanc}iica,Bellis,Filagoger- 

 ynanica, Liula crithmoides. Chrysanthemum Leucanthemum, Senecio 

 vulgaris, S. Jacobcea, Carlina, Carduus tenuiflorus. Cnicus lan- 

 ceolatus, C. arvensis, in very limited quantity over a small area. 

 Centaurea Scabiosa, Hieraciuvi Pilosella, Taraxacum officinale, 

 Sonchus oleraceus. The last is in the same case as Malva sylves- 

 tris ; not uncommon on very out-of-the-way cliff-tops and faces, 

 sometimes growing on bare rock, like the little spleenworts or 

 Draba aizoides. Calluna, and the two common heaths. Limonium 

 binervosum in very varying forms and sizes, dwarf plants being 

 without the barren branches which the larger forms bear. Statice 

 maritima in increasing quantity towards the end of the Head : 

 white flowers occasionally. Prinmda veris is common and luxu- 

 riant. Glaux in one small patch on rocks between two of the 

 " islands." Anagallis arvensis, drawn up among gorse and other 

 vegetation, and also in smaller forms on one if not two of the 

 "islands"; it also occurs in small plants about the cliff slopes and 

 faces of the neighbourhood, more often among other vegetation, e. g. 

 Trifolium scabrum, T. striatum, Lotus, &c. It is clearly at home 

 there, is quite common, and by no means favours the barer spots 

 exclusively. Ligustrum, Centaurium timbellatum, Myosotis versi- 

 color. Convolvulus arvensis, Veronica arvensis, officinalis, and 

 Chamcedrys. Euphrasia curta var. glabrescens. Thymus, Cala- 

 mintha Acinos, Ajuga reptans, Plantago lanceolata, maritima, and 

 Coronopus. Beta maritima, Atriplex deltoidea, Polygomim avicu- 

 lare, one small patch at the summit of the furthest "island," in 

 one of the common forms, not var. litorale, Bttmex crispus, 

 B. Acetosa, Euphorbia portlandica, Urtica dioica, with the Hedera 

 and Heracleum, Parietaria, Scilla verna. S. non-scripta grows in
