This species occurs chiefly in hilly places. The stem and the prickles, which are unequal, are dark-red with appressed and widespreading hairs. The prickles are large, unequal, almost confined to the angles. The leaflets have a white or ashy felt below, the terminal one roundish, inversely egg-shaped, with a long, narrow point. The panicle is rather narrow, loose, nearly cylindrical. The prickles, like those on the stem, are slender, widespreading. The upper leaves are conspicuously white or ashy-felted. The sepals have a pale velvety felt. It is characterized by the unequal, bright-red prickles on stem and panicle, rachis, the white felt on the rachis, sepals, and under surface of the leaflets. The plant resembles R. praeruptorum.
The habitat of this species is hedges. It has an arching, prostrate stem, the prickles slightly swollen at the base, with unequal glands and acicles, the leaflets coarsely, unequally, and doubly toothed, softly hairy only on the veins below. The panicle is long, narrow, leafy, the rachis straight, prickles slender, bent down. The sepals are egg-shaped, aciculate, with long bristles. The plant flowers in July and August.
The habitat of this species is bushy places and heaths. The habit is prostrate. The stem is nearly smooth, blackish-purple (hence melanodermis), with a few intermediate prickles on the faces. The large prickles are strong. The leaflets are plaited, green, the terminal leaflet inversely egg-shaped, blunt, with a long, blunt, narrow point. The panicle is narrow, cylindrical, with short, strongly-ascending lower branches, forming a raceme, and the upper branches are very short. The sepals are bent back in flower and fruit. It differs from R. melanoxylon in being less glandular, and in leaf and panicle; and from R. Bloxamii in the paler, more hairy stem, shorter prickles, more lobed leaflets, etc.
The habitat of this plant is open woods, bushy places, and commons. The habit is arching-, prostrate. The stem has many widespreading, clustered, and single hairs. The stem is fuscous, and so are the unequal prickles. The large ones are numerous and fairly strong, with a slender yellow point. The leaflets are thick, softly hairy below. The terminal leaflet is rather broad, oblong, oval, with a fairly long, narrow, blunt point. The panicle is broad, usually very large, long, broadly cylindrical to blunt, with strong sickle-like prickles, and several simple leaves, the branches mostly equal, widespreading. The rachis and flower-stalk have a dense, soft felt. The sepals are clothed externally with long yellowish-grey hair, rising as the fruit forms. The stamens are only just longer than the style. The plant is characterized by the soft hair on the stem and rachis, the thick, broad, soft leaflets, long, cylindrical, blunt panicle, with widespreading branches. The plant flowers in July and August, and is a deciduous shrub.
Rubus Lejeunei, Wh. and N. - The habitat of this plant is woods and hedges. The habit is arching, prostrate. The prickles on the angles of the stem are slender. The leaves are 3-4-lobed. The leaflets are bright green, thin, hairy below, the terminal one inversely egg-shaped, and rhomb-oidal. The panicle is loosely pyramidal, forming a corymb, with slender, unequal armature. The rachis and flower-stalk have scattered, unequal, stalked glands, and a few gland-tipped bristles. The prickles are slender. The sepals are bent back, with close greenish-grey felt, and many protruding stalked glands and acicles. The plant flowers in July and August, and is a deciduous shrub.
