More
Inflorescences densely strobilate, 1–4.5 cm long; peduncle 3–6 mm long; pedicels 2.5–3 mm long; bracts pale green tinged yellow, brown or red, 6–12 × 6–18 mm, obovate, round or rhombic, divided into two rounded lobes for one-third to three-quarters or sometimes their entire length; bracteoles thin, 1.5–4 × 0.8–1.3 mm, narrowly ovate to lanceolate, often with a few tubercular-based short marginal cilia giving a faintly toothed appearance.
Small woody subshrub 0.3–0.5 m tall with several diverging branched stems from a woody rootstock; young stems with a very few short stout bristles but otherwise glabrous or rather densely covered with very short tubercular-based hairs, purplish and usually with a whitish bloom.
Seeds chestnut-brown, 3 × 2.5 × 1.8 mm, irregularly quadrangular or rounded-reniform, obscurely obtusely beaked at one end beyond the small round eccentric hilum.
Fruit of 1 round or somewhat squarish article, 4–5 mm long and wide, the upper margin ± straight, lower strongly curved, slightly granular in texture.
Calyx lobes 5–7.5 × 3–3.5 mm, oblong or elliptic-ovate to ovate, the upper entire, the lower very shortly 3-fid.
