Description
Flower closeup

It is an aboveground perennial and a herbaceous, stolon-former plant that reaches heights of 10 to 20 cm. The stem is creeping to ascending and forms knots at the roots.

The leaves are opposite. There are two pairs of leaves just below the inflorescence. The leaf blade measures (0.7) 1.4 to 3 (4.5) × (0.6) 1.3 to 2.2 (3) centimetres and is ovate to broadly ovate or almost circular. It has pressed, articulated hair, and mainly has reddish or black glandular points on the edge.

Inflorescences

The flowers are heaped upside down at the end of the stem in two to four. The flowers are colored yellow with a red eye. The ovary is hairy. The flowering period extends from spring to summer.[1]

Distribution

It occurs in China, Bhutan, northeast India, Nepal, Sikkim, Myanmar and Thailand in moist forest edges, bushes and the edges of rice fields at altitudes of 200 to 2100 meters.
