Sub-sp. 



R. DTJMETO'BUM, Weihe ; stem between arching and trailing sub- 

 cylindric sometimes pruinose, bristles few or many, hairs or few on the 

 barren shoots, generally fewer on the rachis of the panicle than in all the 

 following, leaflets broad finely grey-pubescent or subglabrous beneath, 

 lateral pairs much imbricated, toothing open but not long, terminal subor- 

 bicular, sepals reflexed or ascending not leaf-pointed, petals broad, drupes 

 few large. It. nemoro'sus of many, scarcely of Hayne. The glandular 

 representative of corylifo'lius in fruit, leaves, and prolonged flowering. E. 

 tubercula'tus, Bab., is a variety with subequal prickles, appressed sepals, few 

 bristles and glandular hairs. E. diver sifo'lius, Lindl., has more copious and 

 irregular prickles and sepals mostly reflexed. R. emersisty'lus, Mull. (E. 

 JBriygs'ii, Blox.), is near diver sifo'lius, but stems more hairy, leaflets round, 

 and calyx appressed to the fruit. E. concin'nus, Baker, has subequal 

 prickles, smaller and less coarsely toothed leaflets and reflexed sepals. 

 Common in hedges, England and Ireland ; very variable. 



Sub-sp. K. RAD'ULA, Weihe ; stem arching angular, prickles strong subequal, 

 bristles hairs and glands of barren stem copious, leaflets not imbricated 

 grey or often white-pubescent beneath, toothing moderately fine in the 

 typical form, terminal leaflet obovate, sepals reflexed not leaf -pointed, 

 petals broad. E. ru'dis, Weihe, is a variety with stronger prickles and 

 leaflets deeply and very irregularly toothed. E. Leighto'ni, Lees, denticula'tus, 

 Bab., mutabilis, Genev., and obli'quus, Wirtg., are closely allied. Common 

 in hedges, from Fife southd. ; Ireland. 



Sub-sp. R. BLOXA'MII, Lees ; stem arching angular, prickles smaller than in 

 the preceding, subequal, hairs bristles and glands moderately numerous, 

 leaflets not imbricated moderately coarsely toothed green finely-pubescent 

 beneath, terminal suborbicularoften cordate, sepals reflexed not leaf -pointed, 

 petals broad. E. sca'ber, Weihe (jBabinyto'mi, Bell Salter), is an allied form 

 with stronger prickles and the panicle often very large and lax with patent 

 branches. E. fusco-a'ter, Weihe, is a rare form connecting this with 

 villicauflis. Local, from Durham southd. 



Sub-sp. R. KCEHI/EJRI, Weihe ; stem trailing nearly terete, prickles very 

 numerous irregular strongly hooked, bristles numerous, glandular and simple 

 hairs few, leaflets not imbricate pubescence thin grey, toothing moderately 

 coarse, terminal orbicular, sepals reflexed not leaf -pointed, petals broad. 

 E. cavatifo'lius, Miill., is a subglabrous form with few hairs and bristles, 

 leaflets not tomentose hairy on the veins beneath terminal cordate, panicle 

 abrupt with short thick terminal peduncles. JR. infes'tus, Weihe, is a variety 

 with an arching stem, prickles and bristles much less dense. From the 

 Clyde southd. ; Ireland.
