Dunn. Carduus vivariensis Jord. — 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 Fugillus under the above name. It grows plentifully among the dry hills in the province of Ardeche, S. France, and differs from C. acanthoides in inner phyllaries shorter than flowers on pappus ; heads 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, AtripleXf &c., covers the whole ground. In the beginning of September Mr. H. Griffith and I worked over it, and found, among the usual weeds, Melilotus parvijlora Desf., Epilohium tetragonum L., Solarium nigrum L., Linaria minor Desf., Chenopodiwnjicifolium Sm., Panicum Crus-galli, Pea compressa L., all plentiful ; several patches of Cheno- podium ambrosioides L., Panicum. sangiiinale L., P. miliaceiun L. ; a few plants of two natives of our S.W. coasts, Corrigiola litter alis L. and Cynodon Dactylon Pers. (Jide Ar. Bennett) ; and one large plant of Medicago scutellata All. and Trihulus terrestris L. [Zygo- phyllece), Mediterranean weeds. — S. T. Dunn. Erythrtea capitata Willd. in Northumberland. — On July 4th I found this species locally plentiful upon a grassy down of the coast (subsoil sandstone), about 1| mile S. of Newbiggin ; E. Cen- taurium occurred with it, but was very scarce. Mr. F. Townsend, on being asked whether he would place it under the type or his var. spharocephala, wrote : — *' The Erythraa 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 Eogers has identi- fiied it. infestus Weihe, R. pulcherrimus Neuman, and R. SelmeH 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 R. mollis x pimpinelli- folia, being associated with them ; but it only fruited sparingly, and
