KEY TO BRITISH RUBI. 233 



Britain. It has all its st.-l. 5-nate, sharply serrate, and with 

 prominent nerves beneath ; orbicular petals and stain, much shorter 

 than the styles. 



39. R. pyramidalis Kalt. — St. arcuate-prostrate or rather 

 strongly arching, angular, hairy, usually without stalked gland* or 

 with very few. Prickles nearly equal, slightly declining and slender 

 from dilated compressed base. L. 5-nate-digitate and pedate. Lts. 

 yellowish green, doubly acutely serrate, often with some of the 

 teeth patent or recurved, opaque and slightly hairy above, very 

 softly hairy beneath, especially at first; term, elliptic-acuminate, 

 usually rather narrowed to the rounded base, rarely subcordate, 

 occasionally (in sunny spots) subrotund cuspidate-acuminate. Van. 

 truly pyramidal, usually narrowing considerably and very gradually 

 above, with many close 1-3-flowered patent branches and 2 or 3 

 foliaceous bracts ; leafy below. Rachis and ped. thickly clothed with 

 villous hairs and felt ; prickles rather few, subulate ; stalked {/lands 

 unequal, but mostly no longer than the hairs, always present, often 

 numerous. Sep. acuminate, often long-pointed, clothed like the 

 rachis, grey-green, patent when the pet. fall, afterwards reflexed. Pet. 

 elliptic, pink. A very beautiful bramble, just intermediate between 

 R. villicaulis and Ii. leucostachys. Widely distributed. Hedges and 

 wood- borders. 



^ b. R. Eifeliensis Wirtg. — Smaller. St. with more unequal 

 prickles, and a few minute acicles and shortly-stalked glands. 

 Term, and interna. Its. with remarkably long acuminate points. 

 Pan. rather broader and more cylindrical above, with shorter and 

 more distant branches below. Berks, and Dors. Connected with 

 the type by other small forms in Dev. and Hants. 



40. E. podophyllus P. J. Muell., Journ. Hot. 1887, p. 23. — St. 

 prostrate (or very nearly so), bluntly angular, striate, dark purple, 

 with few hairs, and some shortly -stalked glands, and minute acicles. 

 Prickles scattered, in parts crowded, rather small, straight, declining 

 or even deflexed from long compressed base. L. 3-5-nate-pedate, 



mostly 3-nate with lateral Its. gibbous or deeply cleft. Lts. shining, 



dark green above, convex, much paler beneath and soft with many 

 very short white hairs, irregularly acutely serrate, with a few of the 

 larger teeth patent ; lateral oval, with short patent or divaricate 

 stalks ; term, long-stalked, broadly oval or obovate, shortly acumi- 

 nate, subcordate ; petioles, petiolules and midribs rather thickly 

 clothed with small prickles, acicles and stalked glands. Pan. 

 rather lax, cylindrical or subpyramidal, racemose above, with very 

 short hairs and many unequal stalked glands, and slender nearly 

 straight prickles and acicles; branches short, 1-3-flowered, all 

 ascending, except the few 1 -flowered upper ones. Sep. grey-green, 

 hairy and felted, glandular, ovate, loosely reflexed or subpatent in 



fr. Narrow pet., styles and stam. all faintly greenish-white. 



When living, strongly recalls R. ramosus, though separated from 

 it by its prostrate st., very different armature and subracemose pan. 

 It also has obvious affinities with E. pyramidalis and (as Prof. 

 Babington points out) with R. carpinifolius. Merion. (bushy rocky 

 places near slate quarries) and Yorks.
