[Overview]
A perennial 10–20 cm tall, found in slightly moist forests in the subalpine zone.
The stem is erect, branched, 4-ridged, and hairless.
The leaves are simple, in whorls of 4, broadly elliptic to obovate, 0.8–2 cm long and 0.5–1.3 cm wide.
Three veins are conspicuous on the leaf, and stiff hairs grow on the leaf margin and veins.
Of the leaves in a whorl, the true leaves are the 2 that are opposite; the others are stipules of the same shape.
Cymes divided into 2–3 at the stem tip and in the leaf axils bear flowers sparsely.
The flowers are about 3 mm across and pale yellowish green, with a 4-lobed corolla.
The fruit is densely covered with long hooked hairs.
