RUBUS. 69 



rous stout straight yellowish prickles (not all seated on the angles), 

 and with numerous sharp setae and short rigid hairs. The stipules 

 are narrow-lanceolate, eglandular. The common stalk of the leaf is 

 rather long, angular, hairy, eglandular, with sharp hooked prickles 

 pointing backwards, and running midway up the main rib of the leaf- 

 lets. These are all stalked, dark green and very sparingly hispid 

 above, a shade paler beneath and hairy on the veins and nervures, the 

 hairiness very short and inconspicuous. The lower leaflets are com- 

 paratively large, ovate ; the terminal one cordate or roundish and 

 pointed, the length not much exceeding the broadest diameter ; the 

 margin coarsely crenate. — The old stem is angular, striate, rough 

 with old setse. Flowering branch downy, with hooked prickles, and 

 ternate obovate irregularly serrated leaves. Panicle narrow, with 

 numerous pale pink flowers, on erect stalks having a considerable 

 number of setigerous glands. Sepals reflexed, often prickly at the 

 base, pointed with a small mucro. Bears a large quantity of fruit. 



177. R. RADULA. A large Bramble with purplish stout shoots 

 that are often branched. Barren stem obsoletely angular, sulcate, 

 slightly hairy, very rough with unequal prickles, sharp setse and 

 glandular setse ; prickles numerous, either straight or curved and 

 declined, with a dilated base and a sharp point : Leaves quinate, 

 large, on a purplish hairy and setose stalk armed with curved prickles, 

 and with very narrow stipules : Leaflets rather finely serrated with 

 gangrened mucronate tips, green and naked above, hoary beneath and 

 hairy, the midribs prickly as well as the partial stalks : Lower leaflets 

 large, reflexed, from a stalk common to them and the intermediate 

 pair, which are ovate and narrowed at the base, but the terminal 

 leaflet is cordato-ovate, obliquely cuspidate. The young leaves are 

 very downy on the inferior surface. — Fertile stems rough and prickly, 

 sulcate, almost round : Flowering branches elongated, angular, striate, 

 downy, armed vrith prickles which lengthen on the upper parts : 

 Leaves 3-nate, broadly ovate, the lower pair lobed : Panicle leafy, the 

 flower-stalks patent or erecto-patent, covered with a spreading hirsu- 

 ties, setse and stalked glands : Bractese entire, bi- or trifid. Calyx 

 greyish-green, with ovato-lanceolate segments which have a longish 

 point, and become strongly reflexed. Flowers rather large, pink. 



178. R. KoEHLERi. Stem angular or obsoletely angular, brown, 

 striate, rough vnth hairs, setse and glands, and armed with numerous 

 straight prickles which are not much dilated at the base : stipules 

 fringed with stalked glands : Leaf-stalk purple, hairy, setigerous, 

 furnished with curved deflected prickles which frequently run up the 

 midrib of the leaflets : leaflets 5- or 3-nate when the lower are lobed 

 underneath, the terminal leaflet cordato-ovate, pointed, naked above, 

 the nervures of the under surface clothed with very short fine hairs. 

 — F. stem roundish, rough but not hairy, with leaves which are 

 more thickly covered with silky hairs than those of the barren stem. 

 Panicle downy with numerous glandular setae. Calyx reflexed, glandu- 

 lar. Flowers pale pink. Bears a large crop of fruit. Grows in deans, 

 and edges of natural woods.
