Mikania micrantha Kunth

국표에는 없다.

Mikania micrantha is a tropical plant in the Asteraceae; known as bitter vine, climbing hemp vine, or American rope. It is also sometimes called mile-a-minute vine[1] (a moniker also used for the unrelated Persicaria perfoliata). It is known as Japani lota (জাপানী লতা) in Assam.

It is a vigorously growing perennial creeper that grows best in areas in high humidity, light and soil fertility, though it can adapt in less fertile soils. The featherlike seeds are dispersed by wind.[1] A single stalk can produce between 20 and 40 thousand seeds a season.

The species is native to the sub-tropical zones of North, Central, and South America.

Mikania micrantha has ribbed stems that grow up to 6 metres (20 ft) in length with 4–13-centimetre (1.6–5.1 in) long leaves that have a heart-shaped base and a pointed apex. 4.5–6.0-millimetre (0.18–0.24 in) white flowers grow in clusters.
