Rhamnus prostrata Jacq.

This species is quite similar to Rhamnus minuta, but the latter is shorter (not more than 25 cm tall), with obovate or obovate-elliptic leaves not more than 1 cm.

A dwarf decumbent shrub, few cm in height, thorny, thorn at the end of branches, leaves alternate, clustered, 1.8-6 x 1-4 cm elliptic, obtuse, obscurely serrate, glabrous, petiole c.2 mm long, ± pubescent. Flowers solitary axillary, 4-merous greenish, minute, pedicel c. 2 mm long. Calyx lobes ovate-tringular, as long as the tube. Petals minute, narrowly linear. Disc glabrous, stamen exceeding the petals, style 3-fid. Fruit 2-5 mm long, obovoid, black, 3-lobed, seeds c. 2 mm long, somewhat ovoid in shape, slightly grooved bifid at the apex.

Shrubs low, prostrate, deciduous, dioecious, 1-2 m tall, spinescent. Branches alternate, short; young branches spreading, red-brown, puberulent or glabrous; flowering branches often crooked, gray-brown or red-brown, slightly scaly, terminating in a spine. Leaves alternate or fascicled on short shoots; stipules red-brown, subulate-lanceolate, shorter than petiole or slightly longer, puberulent, persistent; petiole 1-3 mm, puberulent; leaf blade abaxially yellow-green, turning yellow when dry, adaxially green, elliptic or ovate-elliptic, rarely oblong, small, 0.2-2.2 cm × 4-10 mm, papery, both surfaces puberulent or subglabrous, lateral veins 2-4 pairs, abaxially slightly conspicuous, often connected near margin, base broadly cuneate, margin inconspicuously denticulate or subentire, apex obtuse or rounded, sometimes emarginate. Flowers yellow-green, unisexual, usually 3- or 4-fascicled on short shoots. Pedicels short, puberulent. Calyx cup-shaped; sepals ovate-triangular. Petals narrowly obovate, cucullate, very small. Disk glabrous. Style 3- or 4-fid. Drupe purple-red, turning black at maturity, obovoid-globose, ca. 5 mm in diam., with 3 or 4 stones, with cup-shaped persistent calyx tube at base; fruiting pedicel 3-4 mm, subglabrous. Seeds yellow-brown, with brownish dots, ovoid-oblong, ca. 3 mm, abaxially with shallow margined furrow extending over 4/5 of length. Fl. May-Jun, fr. Jun-Aug.
