Rubus macilentus - Lean Raspberry

Lean Raspberry is a shrub 1-2 m tall. Branchlets are brown or reddish brown, round, hairy, with unequal long flattebed thorns. Leaves are trifoliate, rarely simple, leaf-stalk 0.8-1 cm. Stalk of end leaflet is 0.5-1 cm, lateral leaflets nearly stalkless, velvety with minute prickles. Leaflets are lanceshaped, ovate-lanceshaped, or ovate, end leaflet much longer than lateral leaflets, 3-5 x 1-2.5 cm, lateral leaflets 1-2 x 0.7-1.4 cm, both surfaces hairless or slightly soft hairy, below with sparse, minute prickles only along veins, base rounded or broadly wedge-shaped, margin sharply toothed, tip pointed, rarely blunt, often shortly tapering on at branch-ends leaflet. Flowers are borne at branch-ends on short lateral branchlets, in 1-3-flowered clusters. Bracts are lanceshaped or linear-lanceshaped, somewhat smaller than stipules, soft hairy. Flower-stalk 6-10 mm, hairy, sometimes with sparse, minute prickles. Flowers are about 1 cm in diameter Sepal-cup below hairy; sepals erect, rarely spreading, lanceshaped or triangular-lanceshaped, 6-8 x 2-3 mm, tip shortly tapering with a tail. Petals are white, broadly ovate to oblong, slightly longer than or nearly as long as sepals, both surfaces soft hairy, base clawed. Stamens many, shorter than sepals; filaments broad, compwoolly. Pistils many, slightly shorter than stamens. The raspberry is orange or red, nearly spherical, hairless or somewhat soft hairy, enclosed in sepal-cup. Lean Raspberry is found in the Himalayas, from Bhutan, N India, Kashmir, Nepal, Sikkim to parts of China. Flowering: April-May.
