Alternanthera sessilis is a perennial but sometimes annual herb that can grow up to 1 m tall. It is erect, ascending or creeping, often widely branched, with robust taproot, solid stems, sometimes floating in water and then fistulose in lower part and with smooth hairs.

The leaves are linear-lance-shaped, oblong to ovate or obovate, measuring 1-15 cm x 0.5-3 cm, and hairless or sparsely hairy. The petiole is 1-5 mm long. 

Its flowering heads are sessile with 1-veined tepals or only 3-veined at the very base, shiny white or purplish. The filaments are united at base into a very short cup.

The fruit is obreniform, corky and measures about 2 mm long. 

Ecology / Cultivation

Alternanthera sessilis is a very common plant of constant or periodically humid, open localities in roadsides, gardens, ditches, swamps, rice fields and tea plantations, and can be found up to 1250 m altitude.
