KEY TO BRITISH RUBI, 



scattered prickles, which are usually slender and declining, but 

 sometimes stout and hooked. Sep. loosely reflexed in the typical 

 plant, brownish grey, with long point, very glandular and aciculate. 

 Pet. obovate, distant, white or pinkish. Stam. white, exceeding 

 the green or reddish styles. Hedges, wood-borders, &c. 



Apparently widely distributed and very variable, especially in 

 Heref. Dr. Focke now combines with it as merely a weak hairy 

 form the R. LoehH Wirtg. Under it also, I suspect, must come 

 most of the British plants which Genevier and Prof. Babington 

 have been inclined to put to R. thyrsifloms W. & N., a species not 

 yet accepted as certainly British by Dr. Focke, though he is rather 

 disposed to combine our 7?. Bloxamii with it as at all events a 

 nearly allied plant. One form, common all along the southern 

 border of the New Forest (v. Joum. Bot. 1890, p. 133), is so marked 

 as to seem to claim varietal rank. It is clearly identical with the 

 Warw. plant referred to as Bloxam's heteroclitus (not of Wirtg. and 

 Muell.) in Journ. Bot. 1878, p. 208. I propose calling it nutans, 

 and should describe its chief distinctive features as follows :— 

 t b. nutans.— Lts. remarkably lengthened at the acuminate point, 

 incise- serrate ; term, very broadly ovate. Pan. very lax and narrow 



above, usually drooping, and overtopped by the very long narrow 



floral l; the short upper patent or divaricate branches seldom 

 more than 1- or 2 -flowered; sep. usually clasping the fr.; styles 

 purplish. This makes some considerable approach towards the 

 following species, going so far in that direction as perhaps to break

short, with a few longer ones, and many straight acicles. Sep.

 woods (Yorks., Norf., Warw., Hants, Somers.).
