The habitat of this species is thickets, hedges, and heaths. The habit is arching, the stem having many flattened prickles, and occasionally acicles and stalked glands, with a very long, broad base. The leaves are convex, 5-lobed, with 3 lobes radiating from a centre, and 2 lateral. The leaflets are the same colour each side, green and hairy on the veins below. The leaf-stalks are very prickly, the terminal leaflet is broadly inversely egg-shaped, with a long narrow point, and heart-shaped. The panicle is long and pyramidal. The rachis and flower-stalk are very strongly armed with prickles, acicles, and stalked glands. The fruiting sepals are loosely turned back. The plant flowers in July and August, and is a deciduous shrub. The soil is siliceous, etc. The plant is close to R. affinis, Wh. & X., and R. infestus, Weihe.
The habitat of this species is woods, thickets, and heaths. The habit is arching, soon nearly prostrate, the stem having unequal bent-back prickles, and is roundish, hairy, often slightly glandular. The leaves are usually 3-lobed, the same colour each side. The leaflets are thin, coarsely and irregularly toothed. The panicle is short, loose, diffuse, with long widely-spreading branches, with few flowers, long slender flower-stalks, usually glandular. The rachis and flower-stalks are softly felted, with few or many sunken glands. The petals are bright-pink. The stamens are pink, not longer than the style, and not united below. The loosely-branched panicle, long flower-stalks, short stamens, and erect fruiting sepals are characteristic. It flowers in June and July, and is a deciduous shrub.
The habitat of this plant is woodlands. The habit is very high arching, or suberect. The stem has some nearly stalk-less glands. The leaves are 3-5-lobed, with 3 lobes radiating from a common centre, 2 lateral, the same colour each side. The panicle is weak and glandular, in a raceme or corymb above. The stalked glands are longer than the hairs. The sepals are externally olive, with narrow white margin, the points embracing the fruit. The carpels are hairy at the tip. The plant approaches the last and R. hesperius.
Rubus hypoleucits, Lefv. & Muell. = micans, Gren. & Godr. - The habitat of this plant is bushy places and open stony ground. The habit is low-arching. The stem is clothed with dense felt, or close, short hair, and is slightly glandular. The leaves are 3-5-lobed, with 3 lobes radiating from a common centre, and 2 lateral. The leaflets are greyish-green, opaque above, with ashy felt and soft hair below, with compound strongly and deeply cut toothing, with a long, narrow point. The panicle is loose, the branches long, nearly or quite widespreading, forming a corymb. The rachis is wavy. The sepals are strongly bent back. The whole plant is greyish. The chief characters are the grey tint, close-haired and felted sepals, deeply-cut leaflets, and wavy panicle rachis.
Rubus hirtifolius, Muell. & Wirtg. - The habitat of this plant is bushy places, hilly districts, and it is locally abundant in West England and Wales. The stem is considerably hairy, rarely glandular or aciculate. The leaves are 5-lobed. The prickles on the panicle have a long base. The leaflets have shining, close hair, and are often much wrinkled above, hairy, with prominent ribs below. The terminal leaflet is variable, usually egg-shaped, with a narrow, long point. The panicle has a long, loose, ultra-axillary top. The rachis and flower-stalk are softly hairy. The petals are narrow, pink, soon falling. The flowers are very-showy, white. The fruiting sepals are wide-spreading-. The fruit is oblong. The soil is siliceous. It approaches R. macrophyllus and R. pyratnidalis, distinguished from the latter by the less velvety leaves, looser, broader, less leafy panicle, ascending fruiting sepals, and oblong fruit.
