The habitat of this species is thickets and hedges. The habit is striking, tall, erect, high-arching. The stem is strong, smooth, and rarely roots. The leaflets are flat or hollowed, nearly smooth above, with pale felt below, with deeply-cut, compound teeth, the terminal leaflet oval, or egg-shaped, with a long-, narrow point. The panicle is long, the ultra-axillary part cylindrical above, weakly armed, the lower branches with sickle-like prickles. The calyx is hairy and felted. The flowers are showy, the fruit fine. The panicle and foliage are exceptionally fine. The plant flowers in July and August, and is a deciduous shrub.
Rubus Godroni, Lecoq. & Lamotte = argentatus, auct. - The habitat of this species is wood borders, bushy places, and hedges. The habit is high-arching at first, then climbing, or bending low and rooting. The stem is pruinose below, hairy. The prickles on stem and panicle are long and rather unequal, straight or sickle-like. The leaflets are rather leathery, shining above, greenish, white-felted, with shining hairs below, 5-lobed, finger-shaped, or with lobes arising from a common centre with lateral leaflets, the terminal leaflet with rounded or nearly heart-shaped base. The panicle is loose, pyramidal, narrowed above. The rachis and flower-stalk are felted, with thick, soft hair. The flowers are showy, with long flower-stalk, bright-pink flowers, the sepals with yellowish-grey felt, and hairs loosely turned back. The pink stamens are much longer than the green styles. The plant flowers late.
This species is found in thickets and hedges, in open ground, at low altitude, and by the sea-coast, being especially common on the East coast. The habit is arching, prostrate, climbing, rooting. The stem is furrowed, pruinose, stellately downy. The prickles have a very wide base. The leaflets are leathery, oval, or inversely egg-shaped, convex, with close, white-felted down below, and the terminal leaflet is inversely egg-shaped, with a blunt point. The panicle is long, narrow, cylindrical. The rachis is furrowed, with strong, stout-based, hooked, and sickle-like prickles. The flower-stalks are also felted and hooked. The stamens are equal to or less than the style. The sepals in flower and fruit are turned back. The plant flowers in July and August, and is a deciduous shrub.
The habit of this Rubus is high-arching at first, then low and rooting, the stem having a rather thick coat of short stellate down. The leaves are 5-lobed, finger-shaped, the leaflets with irregular shallow teeth, grey or greenish, white-felted below, oval or inversely egg-shaped, with a long, narrow point, the terminal one with an entire base. The panicle is rather loose, long, felted, hairy, with widespread-ing few-flowered branches, and strong hooked or sickle-like prickles on the branches. The sepals have an upwardly-curved tip. The plant is intermediate between R. thyrsoideus and R. rusticanus.
Rubus sylvaticus, Wh. & N. - This is an uncommon species found in woods, thickets, by bushy river sides. The habit is arching, prostrate, rarely climbing. The prickles are short, crowded near the base of the stem, awl-shaped. The leaves are 5-lobed. The leaflets are hairy both sides, the terminal one slightly inversely eggshaped, or oval, with entire or notched base. The panicle is dense, long, with small, crowded, needle-like prickles, and softly hairy rachis and flower-stalk. It is not glandular. The fruiting sepals are loosely turned back. The carpels are hairy. The plant is like R. macrophyllus in the small prickles and hairy character, and also like R. villicaulis and R. Lindleianus, but less prickly and more softly downy than either.
Rubus myricae, Focke = var. hesperius, Rogers. - The leaves of this species are broad, 5-lobed, with 3 lobes radiating from a common centre, and 2 lateral ones, with very compound finely-pointed teeth, the terminal leaflet roundish, egg-shaped, with a long narrow point. The panicle is more compound than in the type (not found in Britain), more prickly, with many sunk, nearly stalkless, glands on the rachis, the panicle being long, pyramidal, and compound. The fruiting sepals are widespreading. The plant is like R. sylvaticus and R. hirtifolius.
