Perennial with a woody base and sub-erect to decumbent, herbaceous to slightly woody stems up to 50 cm long, stems more or less distinctly longitudinally ribbed, ribs often minutely tuberculate, older parts covered with a very thin brownish-yellow bark. Leaves subulate-linear to narrowly spathulate-linear (3-)6-15(-25) x (0.3-)0.5-1(-1.3) mm, margins and lower surface irregularly minutely tuberculate, scattered or densely crowded especially on short axillary shoots, often somewhat fleshy. Stipules subulate, 0.2-0.5 mm long. Inflorescence a spike-like raceme, (2-)4-8(-16) cm long. Bracts longer than the sepals, subulatelinear to very narrowly triangular, (2-)2.4-7(-15) x 0.4-0.8 mm with 2 stipuloid appendages about 0.2 mm long on each side near the base, margin and lower surface often minutely tuberculate. Sepals 5, narrowly linear-lanceolate to very narrowly triangular, (1.4-)1.6-2.0(-2.4) x 0.4-0.6 mm, margins and lower surface minutely tuberculate. Petals 2, sometimes almost completely abortive, white, lanceolate-linear to linear or spathulate-linear, (1.2-)1.5-2(-2.4) x (0.2-)0.5-0.6 mm. Stamens usually 3, sometimes 4 or rarely reduced to 2; filaments 1.2-2.4 mm long; anthers about 0.4 mm. Capsule 3.5-6.5 mm long and 2.0-3.8 mm in diameter, ovoid-oblong.
