Aerva lanata (mountain knotgrass) is a woody, prostrate or succulent, perennial herb in the Amaranthaceae family of the genus Aerva, native to Asia, Africa. It has been included as occurring in Australia by the US government, but it is not recognised as occurring in Australia by any Australian state herbarium. The plant sometimes flowers in the first year.
|Aerva lanata var. rotundifolia|
A. lanata is a common weed which grows wild everywhere in the plains of India. The root has a camphor-like aroma. The dried flowers which look like soft spikes, are sold under the commercial names Buikallan and Boor. It is one of the plants included in Dasapushpam, the ten sacred flowers of 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.[unreliable source?]
A. lanata prefers damper sites than A. javanica and can be found in open forests on mountain slopes, on waste and disturbed ground, deserted cultivation and coastal scrub and at altitudes from sea level to 900 m (3,000 ft). It is a common weed in arable fields and bare patches of ground.
