Geographical Distributions
Cleome viscosa is distributed throughout the tropics of the Old World and Australia, and commonly introduced in the New World.
Description
Cleome viscosa is an annual, erect, branched herb up to 1 m tall, with yellowish, glandular hairs, viscid and stinking.
There are 3-5 leaflets. The central leaflet measures 1-3(-5.5) cm x (0.3-) 0.5-1.5 cm, with wedge-shaped base, acute to obtuse apex, and thinly herbaceous, while the petiole is 0.5-6 cm long. The raceme is short to elongate and with largely actinomorphic flowers. The sepals are oblong, and measure (2.5-) 6-7 mm long, while the petals are oblong, measure (4-)7-12 mm long, thin, hairless and yellow. There are (8)10-20(-30) stamens which gradually increase towards the abaxial side. The bluish anthers are 1.5-2 mm long.
The capsule is linear, erect, centripetal-veined, measures (1.5-)6-8(-10) cm long and with beak 2.5-4(-7) mm long.
The red-brown seeds are 1.2 mm in diametre, with narrow cleft, with strong cross-ribs and faint concentric ribs.
Ecology / Cultivation
Cleome viscosa is a weed, very tolerant and ruderal, and occurs on fallow lands and fields, along roadsides, on rubbish heaps, often on sandy, but sometimes on calcareous soils, both under seasonal dry and ever-wet conditions, from sea-level up to 500 m altitude.
