— Peduncles short, glabr., more rarely hispid-glandular. 
Styles woolly, short, capitate .... 46 
46. Leaflets elliptic-obovate, often slightly cuneiform at the 
base and, the lateral ones especially, rather enlarged 
and obtuse at the top, gen. very gray-tomentose 
(with close tomentum); teeth gen. simple. Cor. bright 
rose-coloured. Prickles coarse, hooked. Differing from 
R. dumetorum in its more bushy habit, shorter ped¬ 
uncles, hidden by large bracts, darker fls, styles short 
and woolly, and cal.-divisions erect on the fr. and per¬ 
sist. for a longer time.—Yar. with double toothed leaf¬ 
lets (liomologa Gren.): also: b. Bouvernierana Crep. 
Peduncles and cal.-divisions covered'with stip. glands; 
leaflets irreg. toothed, yellowish green. Wall. — c. cinerea 
Rap. (coriifolia-mollis?). Peduncles and cal.-divisions 
glandular, teeth and petioles with numerous glands; 
prickles suddenly dilated at the base. Saleve, Randa.— 
d. Bdlevallis Pug. Leaflets glabr. above, grayish green 
underneath and hairy only on the central nerve; cor. 
pale. Bovernier.—Mountains and subalp., fairly distrib. 6 
coriifolia Fr. 772. 
— Leaflets elliptic rather narrowed at both ends, with 
scattered hairs or almost glabr., bright green or 
rather yellowish; teeth deep, simple or with a few 
glands. Cor. pale rose-colour. Prickles numerous, slender, 
almost straight. R. (tomentella) sclerophylla Christ!

47 (37). Cal.-divisions spreading or erect on the fr., persist, 
at least till the colouring of the fr. (Mountain varieties 
often having a bluish bloom on the branches, and the 
nerves of the leaflets, as also the stipules and bracts, 
frequently tinted with red). ..... 48 
— Cal.-divisions re flexed on the fr. (almost applied to 
the cal.-tube), falling early. Peduncles fairly long; 
prickles bent) ........ 51 
48. Prickles vigorous, more or less bent in the form of a 
sickle, and cal.-divisions gen. pinnatifid as in R. canina. 
Peduncles short, gen. glabr. Differing from R. canina 
in the same way as R. coriifolia from R. dumetorum, 
in its more shrubby habit, shorter peduncles, hidden by 
large bracts, cor. of a bright rose-colour, cal.-divisions 
*) Differing from R. tomentella in the form and toothing of the leaflets 
the want of subfoliar glands, the cal.-divisions erect on the fr., the prickles 
slenderer, almost straight; it is more nearly allied to R. concinna. R. sclero¬ 
phylla Scheutz has bent prickles, subfoliar glands, cal.-divisions reflexed 
on the fr. and glabr. styles.
