244 Mr. C. C. Babington on the British Eubi. 



with a prominent midrib which is lengthened into an acuminate 

 point. Fruit small and composed of small drupes. 



/3. Bloxamii ; caule anguloso laterihus planis striatis, aculeis parvis, 

 aciculis setisque brevissimis, paniculse ramis brevibus paucifloris 

 corymbosis. 



Week Hill_, Selborne, Hampshire, Dr, Bell Salter. ^. Very 

 abundant in a lane by Hartshill Wood, Warwickshire, but on the 

 opposite side from the wood. Rev. A. Bloxam. July. 



Obs. 1. In some respects this plant approaches R. thyrsiflorus 

 (Weihe), but in that the greater part of the panicle is extra- 

 foliaceous, in this it is leafy to the end. From R. Kcehleri, to 

 which it has some points of resemblance, it is separated by the 

 sectional characters. From the three following species it is 

 abundantly distinguished by its stout aciculi and setae, usually 

 ternate leaves and large floral leaves. The dentate-apiculate 

 margin of its leaves distinguishes it from all the British species 

 except R. LeightonianuSj with which however it cannot be con- 

 founded, that not being a glandulose plant. 



Obs. 2. The var. p. Bloxamii has a panicle of very different 

 aspect from that of the typical R. Babingtonii, the branches being 

 short and distinctly corymbose, the floral leaves larger, especially 

 towards the summit of the panicle, and more usually pilose. The 

 prickles of the growing shoot are neither so numerous nor so 

 strong, the setae and aciculi are very short and more equal, the 

 hairs much more numerous ; the leaves more frequently quinate. 

 In one instance the terminal leaflet of a ternate leaf is subdivi- 

 ding at its base as in R. suberectus, so as to form a partially pin- 

 nate leaf. 



19. R. rudis (Weihe) ; caule arcuate procumbenteve paululum sul- 

 cato aspero, aculeis subsequalibus validis declinatis in caulis an- 

 gulis permulto locatis aciculis setis pilisque sequalibus multo lon- 



• gioribus, /o/z/5 quinatis grosse duplicato-serratis subtus albis, pa- 

 niculse longse foliosse superne ultra- axillaris ramis corymbosis as- 

 cendentibus, sepalis lanceolatis aciculatis setosis a fructu reflexis 

 petioloque adpressis. 



R. rudis. Bell Salter in Ann. Nat. Hist. xvi. 367. 



Stem dark fuscous. Prickles not passing into the aciculi or 

 setae. Leaves dark green above ; lower pair of leaflets stalked. 

 Panicle much-branched ; prickles long, slender and nearly hori- 

 zontal ; rachis usually very setose. Sepals generally ending in a 

 fohaceous point, clothed with dark setae.
