the Botanical Exchange Club {Report, 1890, 285 ; and 1892, 361), 

 and given as a new county record for Salop in this Journal (1893, 

 21). It differs, however, from R. opacus not less than from the 

 others above named, and Dr. Focke has now fully admitted its 

 distinctness. I have great pleasure in dedicating it to one who has 

 done more than any other in recent years to elucidate the study of 

 British Eubi, and who has in particular taken much trouble in the 

 working out of this plant as a species. 



Rubus Rogersii, n. sp. Stem 3-7 ft., erect or suberect, 

 glabrous, with numerous sessile glands, sulcate while young, 

 eventually plane between the angles ; purpur ascent in exposure ; 

 prickles numerous, subpatent or declining, nearly straight (except 

 when young), rather long and strong, subulate from a dilated 

 compressed base, usually confined to the angles. Leaves 5- some- 

 times 7-nate ; petioles plane, pubescent above, with many small 

 strong hooked prickles ; leaflets firm, flat, finely and mnly sen-ate 

 with crowded subsimple serrations, greyish green with soft dense 

 pubescence beneath; terminal cordate-acuminate, gradually narrowed 

 to a fine point ; basal oblong-obovate acuminate, shortly stalked. 

 Panicle bluntly pyramidal, rather lax, often broad and much 

 branched, leafy to the top . radii* eery jl. xuous, more or less hairy 

 armed with many strong prickles declining from a much dilated 

 base or slightly hooked ; branches ascending, lower leafy ; sepals 

 ovate-deltoid with linear tip, long, green or greyish green and 

 more or less pubescent outside, with a grey tomentose margin, 

 laxly reflexed; petals elliptic, shortly narrowed at the base, 

 pinkish white ; stamem short, hardly equalling the greenish styles 

 at first, eventually rather longer ; fruit with some scattered hairs. 



Ii. Rogersii differs from both R. / ieat i* and /". opacus in the 

 more compound prickly and leafy panicle and the reflexed sepals ; 

 from the former also in the cordate-acuminate terminal leaflet and 

 greater pubescence of the leaves, and from the latter in the short 

 styles ; from R. ajftnis in the shorter prickles usually more dilated 

 at the base, shoots not arching over nor trailing and rooting at the 

 tip, leaves greyer beneath and flatter, and short stamens ; from Ii. 

 nitidus in the occasional 7-nate leaves, the shorter and less curved 

 prickles of the rachis, the leafy panicle, reflexed sepals and shorter 

 stamens ; and from all four in the very fine and very crowded leaf- 

 Its distribution is for the present :— (3) S. Devon, W. M. 

 Rogers; (27) Norfolk E. ; (40) Salop ; (57) Derby ; and in Ireland, 

 Co. Down, Hb. W. M. Rogers (collected by Rev. C. H. Waddell). 



SHORT NOTES. 

 Note ok Ipomoea. — In the process of arranging Dr. Welwitsch's 

 fruit collection, some specimens of Ipomoea have come to light, 

 which, in view of recent papers in this Journal, seem of sufficient 

 interest for a brief note. The numbers cited are those of his fruit
