fall. Pet. obovate, with long claw, white, or 



Whole plant remarkably pale in colour; rather like 7?. Lindlei- 

 anus, but with very different pan. and leaf-serration. 



b. stenophyllus (P. J. Muell.). — A S.W. Surrey plant which Dr. 

 Focke has thus named has much narrower Its. than carpinifolius, 

 narrowly oval or obovate acuminate, — with thick soft felt beneath, 

 and larger and nearly simple serrations ; while the narrow racemose 

 pan. is only slightly armed ivith slender declining or falcate prickles. 

 Dr. Focke says that stenophyllus does not occur in Germany, and 

 that he would combine with it "what the French call carpinifolius." 

 Genevier, however, considered that both carpinifolius and steno- 

 phyllns grew in the Loire basin. 



18. E. rhombifolius Weihe. — St. arcuate-prostrate, bluntly 

 angular, with a few scattered short hairs. Prickles declining from 

 a dilated base, usually red. L. 5-nate, conspicuously digitate ; 



petioles and petiolules strongly armed ivith falcate and deflexed prickles 

 extending some way up the midribs. Lts. somewhat doubly serrate- 

 dentate or crenate -dentate, with less wavy edge than in R. villicaulis 

 and R. carpinifolius; all rather narrow and long -stalked, nearly uniform 

 in shape and more nearly so in size than usual ; hairy and shining 

 above, paler green and softly hairy or (sometimes in sunshine) 

 whitish-felted beneath ; term, rhomboid or elliptic, narrowing very 

 gradually into the long acuminate point, and (in a less degree) 

 towards the entire or rarely subcordate base. Pan. long, leafy, 

 loosely pyramidal, ivith rather flexuose rachis and many strong falcate 

 prickles; upper branches close, patent, 1-flowered or few-flowered, 

 usually with one or more very narrow simple leaves ; the lower 

 distant, long, ascending, cymose, or racemose. Bracts often qland- 

 eiliate. Sep. reflexed in fl. and fr. Pet. narrow, obovate-cuneate , 

 bright pink. Stam. (pink or white) exceeding pink styles. When 

 fresh, looking just intermediate between R. carpinifolius and the 

 more glabrous forms of 7?. villicaulis. Commons and heaths. 



19. R. villicaulis Koehl. R. calvatus Blox. — St. arching, often 

 sulcate, with many or few patent hairs, not unfrequently becoming 

 bald. Prickles nearly straight or declining from much-dilated base. 



L. 5-nate- digitate, broad, concave, rarely 7-nate. Leaf -toothing com- 

 pound and very acute, giving a wavy outline to It. Lts. wrinkled, 

 shining, hairy above, paler and soft, with many hairs beneath ; 



term, broadly ovate-cordate or sub rotund cuspidate- acuminate. Pan. 

 leafy , sometimes up to the rather broad top, long, occasionally glandular; 

 subcorymbose above ; rachis flexuose, with rather long subequal erect- 

 patent or divaricate cymose branches. Sep. reflexed in fl. and fr. 

 Pet. oval, bright pink, or rarely white. Stam. white, usually far 

 exceeding the greenish styles, though in the nearly glabrous form 

 common in S. England falling short of them. 



In Scotland the species seems often much hairier. Bloxam 

 gave the name calvatus to more than one form of R. villicaulis, and 

 not even chiefly (it would seem, from the numerous specimens of 

 his naming in my possession) to the very marked plant of Warw., 

 Derb., and Leic. Hedges and heaths.
