Identification

Leaf

Kind	Shape	Feature
Bipinnate	alternate	Borne on stalks (i.e. petioles) 15-60 mm long. They consist of one or two pairs of branchlets (i.e. pinnae) that often have a covering of stiff, prickly, bristles. Each of these branchlets (2.5-8 cm long) bears 10-25 pairs of small dark green leaflets. The leaflets are elongated or oblong in shape (6-15 mm long and 1-3 mm wide) with entire margins. Both surfaces of the leaflets are sparsely hairy (i.e. puberulent) and their margins are lined with tiny bristly hairs. The leaves are very sensitive and fold up when touched (they also fold up at night).

Flower

Type	Size	Color and composition	Stamen	More information
Bisexual	axillary	Pink	4	The pink or purplish coloured flowers are arranged in small, fluffy, globular or egg-shaped (i.e. ovoid) clusters (9-15 mm across). These clusters are borne on bristly stalks (i.e. peduncles) 1-4 cm long in the forks (i.e. axils) of the upper leaves. Individual flowers have four tiny pink petals (about 2 mm long) and four minute sepals. However, the four pink stamens (8-20 mm long) are the most prominent part of the flowers and give them a fluffy appearance

Mode of Propagation

Seeds

How to plant/cultivate

Seed - it has a hard seedcoat and may benefit from scarification before sowing to speed up germination. This can usually be done by pouring a small amount of nearly boiling water on the seeds (being careful not to cook them) and then soaking them for 12 - 24 hours in warm water. By this time they should have imbibed moisture and swollen - if they have not, then carefully make a nick in the seedcoat (being careful not to damage the embryo) and soak for a further 12 hours before sowing.
