It is an annual herb with a sprawling stem. The stem can root at the nodes (very few do not sprawl), reaching over 1 meter in length, with many branches. Some branches have further branching at each node, and they may be either hairless or have a row of short stiff hairs, or covered entirely with short stiff hairs. The leaves are lanceolate, or ovate in the lower part of the branches, 3-12 cm long, 0.8-3 cm wide, usually tapering at the tip, sometimes blunt, hairless or with stiff hairs; red spots are often present on the leaf sheaths, with stiff hairs only along the margin and on one side, or covered entirely with stiff hairs. The scorpion-tail-like umbel inflorescence usually arises singly in the upper leaf axils of the branches, sometimes appearing falsely terminal, with generally only one inflorescence per branch; the bracts have a 2-4 cm long stalk, folded, becoming ovate-lanceolate when spread out, tapering or shortly tapering at the tip, heart-shaped or rounded at the base, hairless on the outside or covered with short stiff hairs; the inflorescence branches dichotomously from the base; one branch has a 1.5-2 cm long peduncle, perpendicular to the bract, forming a straight line with the bract's stalk, bearing 1-4 flowers, extending far beyond the bract but sterile; the other branch has much shorter peduncles, forming a right angle with it, aligning with the bract's direction, bearing 3-5 fertile flowers, hidden within the bract; the bracts are extremely small, almost invisible; the flower stalk is about 3 mm long, elongating to 5 cm during fruiting, stout and curved; the sepals are elliptic, shallowly boat-shaped, about 3-4 mm long, persistent, hairless; the petals are blue. The capsule is rectangular-triangular, about 5 mm long, 3-locular, with two seeds in each of the two ventral locules, which split open, while the dorsal locule contains only one seed, which does not split. The seeds are black, ovoid-oblong, about 2 mm long, with a coarse reticulate pattern, within which there are finer reticulations. The flowering and fruiting period is from May to November.
