Tender herb with stems straggling, procumbent or ascending, branching dichotomously, often rooting at the lower nodes, quadrangular, glabrous or papillose (especially above); leaves rather widely spaced. Leaves on glabrous petioles up to 1 cm long; lamina 1-3.5 x 0.6-3.0 cm, ovate to very broadly ovate, apex acute or subacute and shortly apiculate or occasionally rounded or obtuse, cordate, truncate or abruptly cuneate at the base, 3-7-nerved at the base, glabrous; stipules c. 1 mm long, interpetiolar, deeply fringed or composed of several subulate segments.

A straggling herb with procumbent and more or less ascending branched stems, often rooting at the lower nodes, quadrangular, glabrous or papillose especially in the upper internodes; internodes slender, generally 2–6 cm. long.. Leaves opposite, blades ovate to very broadly ovate, acute or subacute and shortly apiculate or even rounded at apex, cordate, truncate, or shortly cuneate at base, 1 cm. long and 0.6 cm. broad up to 3.5 cm. long and 3.0 cm. broad, 3–7-palminerved, glabrous; petioles 2–7 mm. long; stipules inter-petiolar, about 1 mm. long, deeply fringed or composed of a number of subulate segments.. Cymes terminal or axillary, often loose on long slender peduncles and with slender branches; pedicels at anthesis mostly 3–5 mm. long.. Sepals narrowly lanceolate, acute, 3.5–5 mm. long, keeled along the papillose midrib, with one nerve on each side; the flowers (presumably the sepals) are said to be sticky.. Petals 3 mm. long, white.. Ovules usually about 3.. Seeds 1.5 mm. in greatest diameter, bluntly tubercled.. Fig. 4.

An annual herb. It climbs or creeps along the ground. It has branches that divide in two. It often forms a dense ground cover. The stems form roots at the nodes. The leaves are small, opposite and heart shaped. The leaves are 0.8-2 cm long by 0.5-2 cm wide. The flowers are small and white. The are in twice branched heads at the ends of the stems. The fruit is a capsule. It splits to release small seeds.
