RUBUS. 



obscure points and a few imperfect setse. The prickles are of moderate 

 size, not numerous, with a purphsh dilated base and a straight yellow 

 pungent point. The leaves are dark green, 5-nate, with flat spreading 

 leaflets, on a purple stalk armed with curved prickles and a few setae : 

 Leaflets all stalked decidedly, coriaceous, cordato-ovate, tapered to a 

 point, glabrous on the upper surface, hoary beneath with prominent 

 veins and hairy nervures, and the margin irregularly serrated with 

 purplish serratures (fig. 3, d). The flowering branches are elongated, 

 striate, hairy or villous with deflexed prickles and numerous glandular 

 setae. The sepals become perfectly reflexed, are glandular, and have 

 a rather long mucronate point. The flowers are pale pink, and con- 

 tinue to be evolved until late in autumn. 



Dr. Bell Salter has a variety /3. 1'oseus, in which the flowers are 

 bright rose-coloured. A bramble so distinguished is also met with in 

 our hedges ; and in habit and mode of growth, it agrees with R. 

 carpinifolius ; but I rather refer it to R. rhamnifolius because of the 

 shape of the leaves. The stem wants the asperities which are usually 

 found on that of R. carpinifolius ; and there are only a very few glands 

 on the sepals and amidst the hirsuties of the panicle. 



175. R. LEUCOSTACHYS. — In deans occasionally. The following 

 description is made from specimens sent to me from Twizell-house by 

 Mr. Selby :--Barren stem arching as usual, purplish-brown on the 

 exposed and dull green on the shaded side, hairy, angular, sulcate ; 

 the prickles rather numerous, of medium size, placed mostly on the 

 angles, with a reddish base and a yellow apex. Leaves ternate, rarely 

 5-nate, on a rather short hairy purplish stalk, armed with a few 

 recurved prickles which are continued up the midribs: Stipules linear- 

 lanceolate, hairy and ciliated, with sometimes a few marginal glands : 

 Leaflets on downy somewhat prickly stalks, green above with a very 

 few short scattered hairs, greyish-green beneath with hairy nerves and 

 veins, unequally and irregularly crenato-serrate, the inferior leaflets 

 more or less lobed, the terminal broadly ovate or cordato-ovate, 

 shortly cuspidate, the length little exceeding the extreme breadth. — 

 Flowering branches green, striated, and hairy, with only a few small 

 deflexed prickles which become more elongated and herbaceous on 

 the upper parts : Leaves 3-nate, with large thin leaflets, not so hairy 

 beneath as those of the barren stem but agreeing with them in form : 

 Branchlets patent or erecto-patent vdth from 7 to 3 flowers and wdth 

 stipular-like bractese, pubescent, without or with a very few glands : 

 Flowers rather large, pale rose : calyx hoary and glandular, the 

 segments reflexed after the fall of the petals, and pointed with a 

 minute mucro. — To this species I refer R. macroacanthus, R. villi- 

 caulis, and several varieties of R. vulgaris of the Rubi Germanici. 



176. R. RUDis. At the sides of woods on a heathy soil and in 

 deans. It is a common species in Penmanshiel. I have never seen 

 it in a hedge. — A strong coarse bramble with powerful shoots that 

 curve in low arches or trail along the ground. The barren stem is as 

 thick as a man's finger, green or dull-purple, with 5 prominent angles 

 so that the space between is concave or channeled, armed with nume-
