On the continent of India this plant is an exotic, and has 
been introduced from the Malay Islands, Probably first from. 
South America to the Philippine Islands, a route by which 
several plants have found their way from the new world, to 
the eastern parts of Asia, and from thence the useful kinds soon 
find their way to the westward. See Rumphius’s account of 
the plant, at page 373 of the 5th volume of his Herbarium 
- Amboinense, — 
Root tuberous, not in bundles but single, varying og eneks in 
shape, and with high culture, growing to a very great size; 
outside white, inside much like that of aturnip, Stem ramous, 
sometimes perennial, twining to a great extent. Young parts 
tolerably well clothed with reflexed soft hairs. Leaves ter- 
nate. Leaflets, the pair nearly triangular, the interior one of a 
rhomb-reniform shape; inall, the interior margins are serrate- 
dentate, and somewhat villous on both sides ; size various, the 
largest often six inches each way. Petioles channelled. Sti- 
putes of the petioles ensiform,* those of the leaflets filiform. 
Racemes axillary, from one to two feet long, sub-erect, bear- 
ine numerous fascicles, of large, short, pedicelled, beautiful, 
violet blue flowers inserted on large glandular knobs. Brae- 
tes of both pedicel and calyx small, and caducous. Calyx 
four-parted, the upper lip, or division, broad, emarginate, 
Vexillum sub-rotund; wings semilunate, with a long filiform 
projection at the base. Filaments alternately shorter. Germ 
with a crenulate nectarial ring round the base ; apex of the 
style spirally incurved, almost as in the Phaseoli, Stigma 
large. Legume linear, straight, compressed, laterally con- 
tracted between the seeds, of a dark blackish brown colour;. 
* Can Loureiro’s plant be the same ? he says his is without sti- 
pules, and here they are pretty large, and conspicuous.
