A perennial 50–80 cm tall, found in slightly moist places in hills and fields.
The stem usually does not branch.
The stem and petioles are tinged with red.
Leaves are simple and opposite, ovate with a tail-like pointed tip, and the margin has regular, coarse teeth.
There are 10 or fewer pairs of teeth.
There are male flowers and female flowers.
Male inflorescences arise from the leaf axils in the lower part of the stem and extend in spikes.

It resembles Akaso and Koakaso, but can be distinguished from Akaso by its leaves not being 3-lobed, and from Koakaso by leaf form, such as the number of teeth.
