Ludwigia adscendens is a native of continental Asia, Sri Lanka, Southern China, Japan, and also occurs throughout Southeast Asia to Northern Australia. L. adscendens is introduced as a weed in tropical Africa. [2]

L. adscendens is very common in fresh water pools, swamps, fallow and planted rice fields, and in ditches, as well as occurs from sea-level up to 1600 m altitude. [2]

Botanical Description

L. adscendens is a member of the Onagraceae family. It is a robust, prostrate or ascending herb, much branched and up to measure 60 cm tall. The floating stems are up to measure 4 m long, where the tops are above water, smooth, conspicuous aerophores on the nodes, spindle-shaped and white in colour. [2]

The leaves are broadly oblong-elliptical in shape, with a size of measuring about 0.4-7 cm x 0.7-4 cm, narrowly wedge-shaped base, acute or obtuse apex, with 6-13 pair of veins and with a size of measure 1-2 cm long petiole. [2]

The sepals of the flower are 5 in numbers, deltoid and measure about 5-11 mm long. The 5 petals are obovate in shape, measure 9-18 mm x 6-10 mm, rounded apex, creamy white and yellow in colour at the base. The stamens are 10 in numbers, with a size of measure 2.5 mm long filaments, single pollen and with 4-8 mm long style. [2]

The capsule is measuring about 1.2-2.7 cm x 0.3-0.4 cm, normally smooth, thick-walled, irregularly dehiscent, conspicuously 10-ribbed and pale brown in colour. [2]

The seeds are evident while the pedicel is 2.5-5.5 cm long. The seeds are uniseriate in each cell, ellipsoid in shape, flattened where each is firmly embedded in a cube of woody endocarp. The dark brown in colour of endocarp is fused to capsule wall. [2]


L. adscendens growing under dry conditions have small, crowded leaves, are densely hairy and flower rarely. [2]
