This species is annual; it is found growing on pools 
and: lakes of sweet water, or where water has stood. 
Flowering time the wet and cold seasons. 
Branches or stems round, jointed, flexuous piped, 
tufts of radical fibres from the joints, between the joints 
spongy bodies are formed, which prevent the plant from 
sinking, the roots have not any connection with the earth, 
except when the water leaves it, and then it soon perishes. 
Leaves alternate, bifarious, bipinnate ; pinne two or 
three pair, opposite. Leaflets from eight to twelve pairs 
minute, smooth, possessing much sensibility, I think next 
to that of M. pudica. Stipules cordate, caducous. Pe- 
duncies axillary, single, longer than the leaves, support- 
ing an oblong head of fertile and neuter florets. Bractes - 
Solitary, lanceolate, one-flowered. Fertile flowers above, 
decandrous. Calyx five-toothed. Corol five-petalled. 
Legumes falcate, acute, smooth, from six to eight-seeded, 
torose. Neuter flowers below the fertile ones. Calyx and 
Corol as in the genus, but the ten stamens are here ten, 
linear, lanceolate, waved, yellow petals. iy eee
