Two-Flower Raspberry is a vigorous climbing shrub with tall white, thorny stems, 1-3 m tall. Dark green leaves emerge in spring. Leaves are imparipinnate, 3-foliolate, rarely 5-foliolate; leaf-stalk 2-4 cm, stalk of end leaflet 1-2.5 cm. End leaflet is blade broadly ovate or nearly round, lateral leaflets ovate or elliptic, 2.5-5 x 1.5-4 cm, below densely gray or yellowish gray woolly, with sparse, minute prickles along midvein, above appressed velvet-hairy, base broadly wedge-shaped to rounded, margin unevenly coarsely sawtoothed or doubly sawtoothed, often 3-lobed on at branch-ends leaflet, tip pointed or tapering. Once mature, small clusters of scented white flowers appear on the branches in early summer. Flowers are borne at branch-ends, rarely in leaf-axils, corymbs, 4-6 cm, often 4-8-flowered, or flowers 2 to several in clusters in leaf axils. Axis and flower-stalks are hairless, with needle-like prickles. Flower-stalks are 2-3 cm, flowers 1.5-2 cm in diameter. Sepals erect, spreading at anthesis, broadly ovate or round-ovate, 6-8 x 5-7 mm, tip pointed. Petals are white, nearly round, 7-8 mm in diameter, longer than sepals. Stamens are many, shorter than petals; filaments linear, broader at base. Pistils somewhat shorter than stamens. Aggregate fruit is enclosed in sepal-cup, yellow, spherical, 1-1.5 cm in diameter, hairless. Fruit is eaten. Two-Flower Raspberry is found in the Himalayas, from Kashmir to NE India and China, at altitudes of 1500-3500 m. Flowering: May-June.
