A vory prickly plant, with more numerous sjland-tippofl sot:c 

 tlian tlie otlier Ruhi a«sii. Professor Babin^ton states that tlie 

 ])rickles of 11. tuherculatus are from an obloni^ tulx-reuliform or 

 oval cushion-shaped hase; while in R. altiitrifolius tiiey are from 

 an obloni)^ compressed base; and he also states that the foliafje of 

 tlie latter has a pale glaucous tint not found in the latter. In both 

 iorms the lari^er prickles have proportionately longer bases than 

 the smaller ones. Both occur with ternate leaves and have the 

 leaflets on the barren stem generally hairy only on the veins, 

 wliiie the ternate leaves of the flowering-slioot seem to be al\v;iys 

 felted beneath. Professor Babington has not stated in the tiltli 

 edition of the ^[anual what he now considers a, 0, y oi his 

 former R. nemorosus.

 leaflets thin, green on both sides, uneven above, paler and more 

 or less hairy or even slightly felted beneath, often lobed, doubly 

 or unequally serrate ; terminal leaflet ovate or rhomboidal-ovate, 

 sometimes 3-lobed ; lateral leaflets not overlapping the terminal 

 one. Plowers in a nearly simple often small and sub-corymbose 

 panicle, with the pedicels usually rather long. Rachis and 

 peduncles thinly felted with short hairs, and more or less numerous 

 aciculi, set:e, and slender declining prickles. Sepals ovate-lan-
