Persicaria nepalensis is
a perennial 10-40cm tall found on pathways that run between rice
fields or at damp locations in mountainous regions. The stems branch
well and spread out sideways, inclined to become reddish. Leaves are
of alternate phyllotaxis, each 1-5cm long, oval with the bases
wedge-shaped, and their petioles have wings spreading out to become
a pair of ears-like and embrace the branches. Flowers come a lot on
the branch tops and leaf axils. Bloom time: August-October.
