Description
Corchorus hygrophilus is an ascending herb or subshrub growing to 50cm tall. The branchlets are hairless or sparsely hairy. The leaves are narrow to broadly ovate in shape, with serrated margins. They are 3-12cm long by 1-7cm wide and are hairless or have scattered hairs on both surfaces. The leaf stalks are 10-20mm long and are hairless, apart from a line of short, curly hairs on the upper surface.
The flowers are borne in clusters of 6-8 flowers on a stalk 3-5 mm long arising opposite from the junction of the leaf stalk and stem. Each flower has four egg-shaped petals, about 6-8mm long and 3-4mm wide, with the broadest end outwards. The fruit capsules are broadly ellipsoid or globular in shape and have slight wart-like projections on the outer surface. The fruits are 7-12mm long and 5-7mm in diameter. They contain numerous seeds that are discoid in shape, 2-3mm long and matt dark brown to black in colour. (Halford 1995; Stanley & Ross 2002)
