BRITISH FLORA 



rachis, flower-stalk, and base of the sepals clothed 

 with dense, yellowish-grey, soft hairs. The sepals 

 have a long, narrow point, strongly bent back 

 when the petals fall. The petals are large, bright- 

 pink. The plant is very stout and hairy. It re- 

 sembles most R. mollissimus. 



Rubus pyramidalis, Kalt. The habitat of this 

 species is wood borders, hedges, bushy and 

 heathy places. The habit is nearly prostrate. 

 The prickles are strong and short. The leaves 

 are 5-lobed, finger-shaped. The leaflets are thick, 

 soft, velvety beneath, convex, coarsely toothed. 

 The panicle is long, truly pyramidal, with close, 

 i-3-flowered, short, widespreading branches in 

 the long, ultra-axillary part. The rachis is 

 straight and rigid. The petals are oval. The 

 fruiting sepals are turned back. It flowers in 

 July and August, and is a deciduous shrub. The 

 soil is sandy, siliceous, &c. It is intermediate 

 between R. villicaulis and R. leucostachys. 



Rubus leucostachys, Sm. The habitat of this 

 plant is wood borders, thickets, hedges, and 

 rough banks. The habit is arching, prostrate. 

 The stem is woolly and hairy, densely felted. 

 The prickles are long and nearly straight, very 

 strong. The leaflets are broad, softly yellow and 

 white-felted below, round, wavy at the edge, with 

 nearly simple, even, shallow teeth, the terminal 

 leaflet nearly round, with a blunt point. The 

 panicle is long, cylindrical. There are few stalked 

 glands. The petals are round. The stamens are 

 only just longer than the style. The fruiting 

 sepals are bent back. The plant flowers in July 

 and August, and is a deciduous shrub. 



Rubus lasioclados, Focke. The stem of this 

 plant has a dense mat of felt and long hair. The 

 leaves have also a white felt below, and irregular 

 deeply-cut teeth. The terminal leaflet is oval or 

 roundish. The panicle is broad, very prickly, 

 strongly developed. The rachis and flower-stalk 

 are densely hairy and felted, with crowded, 

 slender, large-based, sickle-like, and bent-down 

 prickles. The petals are white. The plant differs 

 from R. rusticanus in the long hairs on the stem 

 and rachis with straight prickles, more hairy 

 leaves, prickly panicle, white petals, and wide- 

 spreading fruiting sepals, resembling also R. 

 leucostachys, being a cross between the two. 



Rubus criniger, Linton. The habitat of this 

 species is woods and bushy places. The stem 

 is densely hairy and pruinose. The leaves are 

 5-lobed, with 3 lobes radiating from a common 

 centre, 2 lateral. They are greyish-green. The 

 leaflets are not overlapping, irregularly lobed, 

 toothed, ashy-felted, with prominent ribs beneath. 

 The terminal leaflet is egg-shaped, with a long, 

 narrow point. The panicle is narrowed above, 

 the top blunt, with long lower branches, like 

 secondary panicles. The rachis and flower-stalk 

 are covered with very unequal stalked glands and 

 small acicles. The plant resembles R. Gelertii, 

 R. Ley anus, R. Drejeri, and R. scaber. 



Rubus Lettii, Rogers. The habitat of this 

 plant, first found in Ireland (now in two vice- 

 counties there), is woods. The habit is high- 



arching. The stem is stout, bluish-green, clothed 

 with long, fine, shining hairs. The acicles are 

 very unequally scattered, and stalked glands very 

 rare or absent. The prickles are remarkably 

 flattened and straight, long, slender. The leaves 

 are greyish-green, the leaf-stalks long, with many 

 unequal, partly gland-tipped organs. The panicle 

 is cylindrical, the lowest branches moderately long 

 and nearly erect. The rachis has very close, grey 

 felt under the long hairs, with some of the long, 

 slender prickles gland-tipped. The prickles are 

 almost invariably straight and generally widely 

 spreading. The sepals are bent back. The plant 

 is remarkably grey. It resembles R. Questierii 

 and R. micans or R. criniger, distinguished by the 

 flattened slender prickles, inversely egg-shaped, 

 terminal leaflet, more finely-pointed teeth, &c. 



Rubus adenanthus, Boul & Gill. The prickles 

 on the stem of this species are strong, with numer- 

 ous pricklets and stalked glands. The leaves are 

 3-5-lobed, with 3 lobes radiating from a common 

 centre and 2 lateral, greyish-green, with ashy 

 felt below, and compound deeply-cut teeth. The 

 leaflets are ashy-felted and thinly hairy below, the 

 terminal one broadly oval. The panicle is long, 

 glandular, forming a more or less pyramidal 

 corymb. The rachis and flower-stalk have crowded 

 soft hair, which obscures the numerous unequal 

 acicles and stalked glands. The sepals are long, 

 widespreading, with sunken glands and long 

 points ascending when the petals drop. The plant 

 approaches R. micans in leaf characters and hairy 

 stems, but is also like Radulan forms in other 

 respects. 



Rubtis Borceanus, Genev. The habitat of this 

 species is bushy places and hedges. The stem is 

 not felted. The pricklets are usually numerous, 

 with a stout base. The leaves are 5-lobed, with 

 3 lobes radiating from a common centre and 2 

 laterals, and 3-lobed. The leaflets are wavy at 

 the edge, with an ashy felt and hair below. The 

 panicle is cylindrical throughout, the branches 

 rigid and strongly ascending, weakly armed in 

 the ultra-axillary part. The small petals and style 

 are dark-red. The stamens are not so long as 

 the style. The sepals rise when the petals fall. 

 The stout-based pricklets are characteristic, also 

 the unarmed panicle rachis and rigid ascending 

 branches, with small deep-red flowers. 



Rubus cinerosus, Rogers. The habitat of this 

 plant is woods, thickets, and open commons. The 

 stem is very bluntly angled and round, with many 

 very small pricklets, acicles, and bristles, the arma- 

 ture on stem and panicle being variable. The 

 leaflets have broad, shallow, even teeth, with close 

 ashy -felt and rather few hairs below, the ter- 

 minal leaflet roundish, inversely egg-shaped. The 

 panicle is broadly cylindrical, with widespreading 

 branches. The rachis and flower-stalk have an 

 ashy felt, are densely softly hairy, and have many 

 very slender more or less widespreading prickles. 

 The stalked glands are crowded and sunken, with 

 a few gland-tipped bristles. The plant approaches 

 R. pulcherrimus, differing in armature, glands, 

 &c., and shape of panicle.
