The habitat of this plant is woods, thickets, and commons. This species is near the last, but is stronger armed and more glandular. The stem is strong and sharply angled, with stouter, longer prickles on the angles. The leaves are 5-lobcd, the leaflets have a longer, narrow point, with grey felt below, and deeply cut teeth. The panicle is very long, pyramidal, forming a corymb, more prickly and glandular. The petals are narrow, white or pink. The rachis and flower-stalk are densely glandular and aciculate. The sepals have a soft cushion of grey felt hiding the purplish glands. The plant is distinguished from R. Babingtonii by the more unequal armature, thinner, inversely egg-shaped, grey-felted leaves, and pyramidal, loose panicle, with bent-back, fruiting sepals, long stamens, and short loose hair on rachis and flower-stalk.
Rubus cavatifolius, P. J. Muell. - The habitat of this plant is bushy places, hedges, and thickets. The stem is nearly smooth, and pale or reddish brown, like the unequal prickles. The leaflets are yellowish-green, the terminal one very broadly heart-shaped to egg-shaped, with a long narrow point. The panicle is nearly cylindrical, with slightly narrow, blunt top, the branches wide-spreading, with many narrow, simple leaves. The plant is recognized by the pale-yellowish, heartshaped, egg-shaped terminal leaflet, with long point, and spreading branches. The plant flowers in July and August, and is a deciduous shrub.
The habitat of this plant is bushy places. The habit is arching, prostrate. The prickles are large and numerous, often sickle-like. The leaflets are very long and narrow, deeply cut, with close white or grey felt below, the terminal one narrowed both ends, with very long, narrow point, inversely egg-shaped, the basal leaflet stalked, not overlapping. The panicle is strongly developed, very large, nearly cylindrical. The rachis and flower-stalks have crowded sunken glands, acicles, and long prickles. The sepals are bent back. The plant resembles R. echinatus and R. pallidus, Wh. and N. It flowers in July and August, and is a deciduous shrub.
The habitat of this plant is woods, bushy places, and heaths. The habit is arching, soon prostrate, the stem bluish-green, hairy. The larger prickles are rather weak, small, widespreading, purplish-red. The terminal leaflet is broadly inversely egg-shaped, the leaflets convex, coarsely toothed, green, softly hairy both sides, wavy at the edge, the teeth lobed, deeply cut above. The panicle is long, leafy to the top, broadly pyramidal, round-topped, with long, ascending, distant lower branches. The rachis and flower-stalks are straight, stout, densely softly felted. The sepals are white-felted within, widespreading, and star-like when the petals fall. The carpels are very small. The species flowers in July and August, and is a deciduous shrub.
Rubus fuscus, Wh. & N.- The habitat of this plant is woods and open places. The habit is arching, prostrate. The stem is densely hairy. The prickles are rather short, scattered. The leaflets have compound, irregular, coarse teeth, and are softly hairy below, the terminal one rather broad, with a long point. The panicle is narrow, nearly cylindrical, with nearly equal few-flowered branches, with sunken stalked glands and acicles. The plant flowers in July and August, and is a deciduous shrub.
Rubus pallidus, Wh. & N. - The habitat of this species is hilly woods, thickets, and hedges. The habit is arching, prostrate, the stem with prickles usually confined to the angles, with abundant, rather short, somewhat spreading hair. The leaflets are long and narrow, thin, often slightly felted, and soft beneath, coarsely and irregularly toothed, with a long narrow point. The panicle is loose, rather straggly, the upper leaves narrowly egg-shaped, with a long point or linear, the rachis wavy, the flower-stalk slender, the terminal one of the branches often longer than the lateral ones. The glands are stalked, black, and the acicles small. The sepals on the unripe fruit are turned back. The plant flowers in July and August, and is a deciduous shrub.
Rubus scaber, Wh. & N. - The habitat of this plant is open woods, bushy places, and damp hollows. The habit is arching, prostrate, the stem round, bluish-green, downy, the prickles small, strong, short, bent down, rough with small acicles, with short-stalked glands and scale-like tubercles. The leaflets have fine teeth and a short point, and are wrinkled. The panicle is narrow, with short hair and short-stalked glands on the rachis and flower-stalks. The plant flowers in July and August, and is a deciduous shrub.
