SHORT NOTES. 493 



genus represents a good new type of the group Gloeolicbenes 

 (Verhandl. k. k. Zool.-Bot. Ges. Wien, xlviii. [289). It is therefore 

 necessary to recognize its priority over the orchid genus, for which 

 latter I propose the name of Rol/ea, and for the species that of 

 Rolfea elata. — A. Zahlbruckner. 



Arctium nemorosum Lej. in Worcestershire. — In looking over 

 some plants collected in 1885, I find that I have specimens of the 

 above, gathered from three stations in the neighbourhood of Mal- 

 vern. It has not, I believe, hitherto been recorded for this county.

DiANTHus GALLicus IN Jersey. — From Mr. G. C. Druce I have 

 received specimens of a pink, which were sent to him for identifi- 

 cation. They were from St. Ouen's Bay, on the west side of 

 Jersey, and were tentatively labelled " Dianthus ccBsius" by the 

 collector. They certainly do not belong to this species, but almost 

 exactly match specimens of Diaxthus r/allicus which I have examined, 

 and fit in with the descriptions of this plant. D. gallicus is a 

 maritime species, which in France extends from the Gironde to 

 Brest, while D. casius grows on mountain limestone. I am in- 

 formed that it grows under conditions which preclude it from being 

 otherwise than truly wild. — F. N. Williams. 



Cerastium arcticum Lange (p. 440). — Mr. Marshall's note has 

 prompted me to refer to Mr. N. E. Brown's remarks on C. lati folium 

 as a British plant in the Supplement to English Botany, p. 42 (1891). 

 He says : "On comparing the seeds of typical C. latifolium with 

 those of the British plant that has been so named, including var. 

 Edmo7isto7ii, I do not find any difference of kind, but only a difference 

 of degree ; the seeds of the British plant are smaller than those of 

 typical C. latifolium, although considerably larger than those of 

 C. alpinum, but the testa of thoroughly ripe seeds is loose, although 

 nothing like so inflated as in C. latifolium., ... so that I think our 

 plant is really C. latifolium, but a form with smaller seeds, for 

 which the varietal name, Smithii Syme, may be retained." I have 

 examined the material indicated by Mr. N. E. Brown, and am dis- 

 posed to concur with him in adding C latifolium to the British 

 flora. I do not, however, agree with him in identifying C. arcticum 

 with C. latifolium var. Edmonsto7ii, though there may be some 

 difficulty in distinguishing them (in the dried state). All the more 

 reason is there against according to C. arcticum specific rank. Were 

 the characters adduced by Mr. Marshall to be considered of specific 

 importance, I am afraid that the 123 species enumerated in the 

 November number of the Bulletin de VHerbier Boissier would have to 

 be trebled. — F. N. Williams. 



Jungermania obtusa in Britain. — Amongst Mr. Symers M. 

 Macvicar's collection of Hepaticae in West Inverness is a species 

 new to Britain — Jungermajiia obtusa Lindb. After examining it, 

 I had no doubt it was that species, but to make quite sure I sub- 

 mitted specimens to Drs. Kaalaas and Jorgensen, who confirm it. 

 Hitherto it has only been found in Northern Europe, Styria, and 

 Switzerland. — W. H. Pearson.
