Stems 25–60+, erect to ascending, green, 2–4 cm; internodes terete, 1–4 times as long as leaves, shiny, minutely glandular-villous. Leaves briefly connate basally, with herbaceous sheath 0.1–0.3 mm, sessile; blade obscurely 1-veined, narrowly elliptic to lanceolate or ovate, 2–6 × 1–1.5 mm, subsucculent, margins thickened, herbaceous, shiny, ciliate proximally, apex acute to apiculate, pustulate, glabrous; axillary leaf clusters absent.
