478 SHORT NOTES. 



the external, while a local variety [Peplis Portula L. var. longi- 

 dentata Gay) has the outer teeth longest. The latter appears to be 

 the only form occurring in Britain. — S. T. Dunn. 



Carduus vivariensis Jorcl.— a peculiar looking thistle was sent 

 in to the Wild Flower Competition at the Bath Flower Show in 

 August, labelled "Carduus acanthoides." It looked very different 

 from that plant by reason of its very long leafless peduncles. The 

 fruit was fully developed. A similar plant is described by Jordan 

 in his Fufiillns under the above name. It grows plentifully among 

 the dry hills in the province of Ardeche, S. France, and differs from 

 C. acanthoidcs in inner phyllaries shorter than flowers on pappus ; 

 beads on long, almost naked peduncles ; whole plant glabrous, 

 except pedicels. This description and the figure agree well with 

 our thistle, which grows near Mangotsfield Station, in Gloucester- 

 shire. Mr. Smith, of Kingswood, kindly showed me the locality. 

 There were one or two plants only, and close by were a few aliens, 

 so that it may have been introduced with them. It would, however, 

 be interesting to know whether the same plant does not occur else- 

 where in Britain among our C. acanthoides forms. — S. T. Dunn. 



Carlina vulgaris L. — A peculiar habit is assumed by this plant 

 on the sandy dunes at Bude, N. Cornwall, each plant forming a 

 ball or cone of closely packed heads separated from the ground by 

 a rosette of leaves. — S. T. Dunn. 



Somerset Aliens. — At Tiverton, near Bath, great quantities of 

 cinders, &c., have from year to year been deposited on waste ground 

 along the river-bank. A dense growth of Chenopodium, Atriplex, 

 &c., covers the whole ground. In the beginning of September 

 Mr. H. Griffith and I worked over it, and found, among the usual 

 weeds, MeUlotus parviJlo)xi Desf., Epilohium tetrar/onum L., Solamun 

 ni(/i'U))ilj., Linaria minor Desf., Chenopodhun JicifoUum Sm., Panicum 

 Crus-(jaUi, Poa covipressa L., all plentiful ; several patches of Cheno- 

 podium (unhrosioides L., Panicum sanguinale L., P. miliaceum L. ; 

 a few plants of two natives of our S.W. coasts, Corrigiola littoraJis 

 L. and Cynodon Dactijlon Pers. (Jide Ar. Bennett) ; and one large 

 plant of Medicar/o scutellata All. and Trihulus tcrrestris L. [Zygo- 

 phyllecB), Mediterranean weeds. — S. T. Dunn. 



Erythr^ea capitata Willd. in Northumberland. — On July 4th 

 I found this species locally plentiful upon a 'grassy down of the 

 coast (subsoil sandstone), about Ih mile S. of Newbiggin ; 7'7. Cen- 

 taiirium occurred with it, but was very scarce. Mr. F. Townsend, 

 on being asked whether he would place it under the type or his var. 

 spha;rocephaht, wrote : — " The Erythrcca is undoubtedly E. capitata. 

 I do not think now that a varietal name is required." This new 

 station greatly extends its known British range. Among some 

 brambles collected nearer Newbiggin, Mr, Moyle Kogers has identi- 

 fiied Pi. infestus Weihe, B. pulcherrimus Neumau, and Pi. Selmeri 

 Lindeberg ; the first-named, which seemed to be scarce, is an addition 

 to the list for v.-c. 67. A hybrid rose, from a furze-clad bank above 

 the Wansbeck, near its mouth, is probably Pl. mollis x pimpinelli- 

 J'olia, being associated with them ; but it only fruited sparingly, and
