Canavalia rosea is a species of flowering plant of the genus Canavalia in the pea family, Fabaceae, that has a pantropical distribution.[2] Common names include beach bean, bay bean, seaside jack-bean, coastal jack-bean,[1] and MacKenzie bean.[2]
Description
Coastal jack-bean is a trailing, herbaceous vine that forms mats of foliage. Stems reach a length of more than 6 m (20 ft) and 2.5 cm (0.98 in) in thickness. Each compound leaf is made up of three leaflets 5.1–7.6 cm (2.0–3.0 in) in diameter, which will fold themselves when exposed to hot sunlight. The flowers are purplish pink and 5.1 cm (2.0 in) long. The flat pods are 10.2–15.2 cm (4.0–6.0 in) long and become prominently ridged as they mature. The buoyancy of the seeds allows them to be distributed by ocean currents.[2] The plant seems to contain L-Betonicine.
Habitat and range
C. rosea inhabits upper beaches, cliffs, and dunes throughout the world's coastal tropics. It is highly salt-tolerant and prefers sandy soils.[2]
