Capsule ellipsoid or subglobose, 3-4 x ca. 2.5 mm, pericarp membranous, 3-valved, apex with persistent styles, persistent tepals surrounding more than half. Seeds numerous, chestnut-colored, shiny, reniform, smooth, raphe with 3-5 arcuate ribs, between ribs with fine and closely transverse grains"  (Flora of China online).

"Annual herb.  The root is a taproot which is only slightly branched.  The stem is glabrous, prostrate and highly branched and forms dense mats.  The leaves are simple, arranged in whorls of 5 to 6 leaves at each stem joint or node, they are spatulate, 1 to 2.5 centimeters long and entire.  The inflorescence is a simple umbel of white flowers which are small and radially symmetrical.  The fruit is a 3-valed capsule and the seeds are small, orange-red and kidney shaped"  (Cardenas et al., 1972; p. 93).

Habitat/ecology:  "Annual herb commonly found in cultivated fields"  (Cardenas et al., 1972; p. 93).  In China, "barren grasslands, dry farmlands; near sea level"  (Flora of China online).
