An annual herb. It can extend upwards or lie along the ground. It grows 8-22 cm tall. It can form mats. The leaves are 1-3 cm long by 1-5 mm wide. They are narrowly oval. They taper to the tip and are wedge shaped at the base. The flowers can be of 2 or 3 forms. They can occur singly or in small groups. The fruit is a capsule about 2 mm long. The seeds are brown and 0.3 mm long.
Leaf blades 0.7–3.4 cm. x 0.5–4.5 mm., linear to narrowly elliptic, subobtuse to usually acute at the apex, cuneate at the base, scabrid-papillose above, on the inrolled margins and often on the main nerve beneath but mostly glabrous beneath; petiole absent or apparent petiole 1–2 mm. long; stipule sheath 1.2–2 mm. long, with 3–7 long and short fimbriae up to 1.5 mm. long.
Calyx tube c. 1 mm. long, obconic to campanulate, glabrous or sparsely pubescent; lobes 4–8, 0.6–1.1 x 0.2–0.3 mm., triangular or linear-subulate, margins setulose-ciliolate.
Flowers not heterostylous, sometimes solitary at the nodes or few in subsessile axillary fascicles; peduncles obsolete or up to 2 mm. long; pedicels 1–3 mm. long.
