The habitat of this plant is bushy places and hedges. The habit is arching, prostrate. The stem has abundant, somewhat spreading, partly closely - pressed hairs. The leaflets are irregularly and coarsely toothed, the terminal one obtusely angled, inversely egg-shaped, nearly wedge-shaped at the base, which is entire. The panicle is loose and long, forming more or less of a raceme, the upper part long with 1-2-flowered branches, the flowers on long stalks, with acicular prickles. The flowers are very showy. The plant is like R. micans and R. oigocladus, with more unequal prickles, and distinguished by the remarkably hairy stem and rachis, the long nearly naked panicle, numerous 1-2-flowered, long-stalked branches, and handsome flowers.
The habitat of this plant is woods and heathy pastures. The habit is soon prostrate. The stem is nearly smooth. The prickles are rather few, very slender. The leaves are 3-lobed. The leaflets are shining, with close, fine-pointed teeth. The panicle is cylindrical, forming a corymb-like raceme, the rachis wavy, with unequal, partly sunk, stalked glands, and very slender bent-down prickles.
The habitat of this plant is woods, damp, hilly, and shady places. The habit is prostrate. The prickles are short. The leaves are usually 3-lobed. The leaflets are more or less equal, nearly uniform, with shallow, even teeth, the terminal one inversely egg-shaped, with a blunt point. The panicle is pyramidal, forming a raceme above, the flower-stalk and rachis rigid, purple, with dense, short-stalked glands, with grey felt, and short hairs.
The habitat of this plant is sunny spots. The stem is bluish-green, with scattered, unequal, numerous prickles and acicles. The leaves are frequently 4-5-lobed. The leaflets are blunt, with a short point, narrowed at the base. The panicle is less rigid, usually more compound and interrupted than in the last, with larger flowers, less rigid flower-stalk, and hairy carpels. The plant resembles R. longithyrsiger and R. oigocladus.
Rubus foliosus, Wh. & N. - The habitat of this plant is damp woods and bushy places. The habit is arching, prostrate, climbing, in thickets. The prickles are numerous, weak, and subequal. The leaves are mainly 3-lobed. The leaflets are nearly uniform, unequally toothed, paler and downy below, broadest near the middle, with an ashy felt below, the terminal broader near the middle, gradually narrow-pointed, narrowed to the entire or notched base. The panicle is long and narrow, with wavy rachis, with numerous short, few-flowered, tufted branches above, and several egg-shaped leaves with a long, narrow point. The upper leaves have a white felt below. The sepals are egg-shaped, narrow, aciculate, with bristles. The plant flowers in July and August, and is a deciduous shrub, often covering the ground in a wood for long distances.
Rubus rosaceus, Wh. & N. - The habitat of this plant is cleared spots in woods, and wood borders, woods, and hedges. The habit is arching, prostrate. The large prickles are nearly equal, chiefly on the angles, strong but rather short, the short ones slightly exceeding the nearly equal aciculi, setas, and hairs. The stem is round, downy or nearly smooth. The leaves are chiefly 3-lobed. The leaflets are broad, hairy on the nerves beneath, the lateral ones expanded. The terminal one is round. The panicle is broad and spreading, nearly pyramidal, blunt, very glandular and prickly. The petals are bright-pink, and the plant is a very handsome species. The plant flowers in July and August, and is a deciduous shrub.
Rubus horridicaulis, P.J. Muell. (= R.saxicolus, P. J. Muell.). - The habitat of this species is woods and lanes. The stem is stout, blunt-angled, bluish-green, brown, smooth. The large prickles are unequal, scattered, sickle-like, or bent down. The leaves are 3-5-lobed, large, with uneven toothing, green, harsh below. The leaflets are equal, the terminal subrotund, with a blunt point. The panicle is broad, pyramidal, nearly cylindrical, the rachis is very prickly, with mixed armature, the sepals are triangular, clasping the hairy fruit. The petals are pink or white.
Rubus hostilis, Muell. & Wirtg. - The habitat of this species is woods, bushy, heathy ground. The habit is prostrate. The stem is bluntly angled. The leaves are 5-lobed. The leaflets are rather thin, narrow, with very long points, the terminal one with long, narrow point, with a narrow, entire, or notched base, with irregular partly-compound teeth. The panicle is short, forming a raceme or corymb above, loose, with all the branches ascending. The sepals are strongly turned back. The petals are small and narrow. The plant resembles R. echinatus in the strongly turned-back sepals, deeply-cut leaves, but differs in the armature and thin, narrow, green leaflets.
