KEY TO BRITISH RUBI. 887 



quite young), paler and very soft beneath, hairy on both sides, 



i ncise 



or even lobate-dentate in the upper half; term, very broadly roundish- 

 obovate or truncate-obovate, with long cuspidate-acuminate point 

 and rounded or emarginate base ; interm. similar, but narrower ; 



bas. oblong, acute. Pan. lour/, usually leafy to the broad rounded 



top, very lax below, with long ascending branches ; upper branches 

 rather short, crowded and interlacing; rachis and ped. straight, 

 stout, covered with dense felt and long villous hairs nearly hiding the 

 many purple acicles and stalked glands ; the prickles also many, 

 mostly long and slender, declining or falcate. Sep. ovate, abruptly 

 acuminate, clothed like the rachis and white-margined externally, 

 conspicuously white-felted within, patent and star-like when the pet. 

 fall, loosely reflexed in fr. Pet. unusually variable in size and 

 shape, but apparently always white, and usually crumpled and 

 fugacious. Stam. white, usually falling short of the styles. Carpels 

 exceptionally smalL A very hairy plant. Remarkably constant in 

 character, except in the size and shape of the pet., and so one of 

 our most readily recognised brambles. Heaths, hedges, &c. 



Widely but locally distributed ; especially abundant in E. Dors, 

 and S. Hants. 



69. E. rosaceus W. & N. — St. roundish or bluntly angular, 



with 



having 



and stalked glands. Larger prickles (chiefly on angles) strong, 

 nearly equal, declining from large compressed base, L. 3-nate or 

 5-nate-pedate, broad. Lts. coarsely and somewhat doubly dentate- 

 serrate or crenate-mucronate, shining and often subglabrous above, 



hairy 



subcordate 



also exceptionally broad, and deeply cleft beneath. Pan. broad, 

 diffuse, usually rather short, with strong erect-patent branches and 

 spreading or divaricate branchlets, all thickly felted, hairy and purple, 

 with crowded very unequal stalked glands, bristles and acicles ; the 

 prickles mostly small, slender, declining ; the top leafless or nearly 

 so, broad, truncate or rounded. CaL less deeply divided than 

 usual, with very attenuate grey-felted white-margined and glandular 

 "sep.," loosely reflexed or ascending. Pet. showy, usually broad, 

 pink. Stam. pinkish, exceeding styles. Bushy places ; local (in 

 the exact form described). 



However it may be on the Continent, in England it seems 

 impossible to keep rosaceus and hystrix specifically apart. There 

 are, in fact, frequent intermediates between typical rosacms and the 

 three more marked forms, which I propose placing under it as vars. 

 b. E. hystrix (W. & N.). — St. more angular and hairy; some- 

 times very strongly armed. L. more frequently 5-nate. Lts. usually 

 uch narrower, with entire or emarginate base, more irregularly 



sharply serrate, and not unfrequently incised or lobate, 

 wealdy pubescent or downy beneath. Pan. rather long 

 , and usually more leafy, often with very mixed arma-
