Geographical Distributions

A pantropical weed of Central American origin; introduced into South-East Asia long ago and nowadays occurring throughout Malesia.


This is an annual, unarmed, hairy with long soft hairs herb up to 70 cm tall. The stems are sparingly branched near the base.

The leaves are opposite, ovate to ovate-oblong size 1-5 cm x 0.3-2.5 cm. The base is obliquely triangular to rounded while the apex is bluntly pointed. The margin is finely serrate, pale to dark green and often with purple spots. There is a short-stalk with sharply pointed free stipules.

The inflorescence is arising from axils or terminal and composed of inflorescence stalk, 4 minute spherical clusters of flower and lying flat-hairy involucres. The green or purplish glands bear a narrow appendage and yellow anthers.

The capsule is acutely 3-lobed, broadly ovoid-pyramidal, about 1 mm x 1.2 mm and lying flat hairy.

The seeds are oblong, with slight transverse wrinkles.
