Characteristics

Erect rigid shrub or small tree, usually with patent spiny branches, 1.2-4 m tall. Young branchlets quadrangular, grey-brownish, sometimes pubescent or glabrescent. Leaves simple, rarely 1-jugate, sessile to subsessile, 20-50 x 3-10 mm, oblanceolate to linear-oblanceolate, slender, rounded, retuse or emarginate at the apex, tapering at the base, more or less pubescent when young, glabrescent, margins entire, alternate on the young branchlets, 9-13 crowded together in each shortly lanate cushion on the older shoots; cushions always below the short spines. Flowers single or clustered on the cushions; pedicels 6-10 mm long, pubescent. Calyx 5-9 mm long, more or less 5-lobed, pubescent outside, sometimes glandular in the upper part. Corolla golden-yellow, sometimes with reddish streaks, with the tube 15 mm long, minutely hairy in the throat and below the insertion of the stamens; lobes 15-19 mm wide, subcircular, patent, crinkled, emarginate, margin ciliate. Stamens adnate up to c. 10 mm from the base corolla tube; filaments 7-12 mm long; anthers 3-4.5 mm long, not apiculate. Ovary 2-3 mm long. Capsule 5.5-10 x 1.1-1.5 cm long, beaked; valves thin, light-brown. Seeds 1 x 1.8-2.2 cm, including the wings.
