📚 Overview
Description
Global description
Eleocharis limosa is a vivacious marsh plant that grows in dense clumps, leafless, entirely glabrous, with thick rhizomes, more or less clamped. The stems are cylindrical, more or less compressed, undivided transversely, 2 to 4 mm in diameter, reaching more than 30 cm in height. The leaves are reduced to sheaths, without lamina. The inflorescence is reduced to a single dense terminal spikelet, usually multiflora. The glumes are inserted non decurrent, re-cultivated at the top.
First leaves
Plant tufted with dense clumps of erect and clamped stems, sub-cylindrical, completely glabrous, often 2 to 6 centimeters but can reach up to 10 to 55 cm long.
Underground system
Dense and thick rhizomes and roots in bundles at the base and at the nodes.
Stem
The stem is cylindrical, more or less compressed and angular, undivided transversely, 2 to 3 mm diameter and 30 to more than 60 cm in height.
Leaf
The leaves are reduced to short membranous sheaths.

Eleocharis limosa is a vivacious herb that multiplies essentially by its strong rhizomes. The fragments of rhizomes are propagated by water and soil working tools.

Madagascar: Eleocharis limosa grows on waterlogged soils or flooded alluvial soils, rich enough, in sunny places. This species can be found in rice fields in semi-intensive culture system, in the marshes, low lands almost permanently waterlogged, canals and drains the plains and lowland rice farming up to 1500 m altitude.

Local harmfulness
Madagascar: relatively low frequency of species, but locally abundant and very harmful for rice. The clamped stems form a dense stand, impairing the development of rice plants. Eleocharis limosa often develops in more or less flooded rice or experiencing drainage problems, clayey soil texture. It multiplies rapidly by its strong and deep enough rhizomes. This species is less common than E. dulcis but locally abundant in the plains and lowlands rice eastern Madagascar.
