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; pinniB two or 

 three pair, opposite. Leaflets from eight to twelve pairs 

 minute, smooth, possessing much sensibility, I think next 

 to that of JM. pudica. Stipules cordate, caducous. Pe- 

 duncles axillary, single, longer than the leaves, support- 

 ing an oblong head of fertile and neuter florets. Bractes 

 solitary, lanceolate, one-ilowered. 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. 



Note. It agrees pretty well with Miller's figure of M.
