Description

edit
 
Ouret lanata From Kerala.

Mountain knotgrass is an annual with a branching, somewhat woody root system. The stems are mostly straggling and sprawling and spread widely, sometimes as much as 6 feet (1.8 m) in length. The often stalkless leaves are alternate, oval and 0.5 to 1.5 in (13 to 38 mm) long. They grow from whitish papery stipules with two lobes and red bases. The tiny clusters of two or three flowers grow in the leaf axils. The flowers are about 0.1 in (2.5 mm) long, pink, green or dull white. The flowers are normally self-pollinated. Flowering time is from May to October.[7][unreliable source?]
