MACllOLOBIUM bijugum. 

 Tab. XVII. 

 Flowers triandrous. Six sterile filaments. Leaves two-paired. 



Whence or how introduced into the botanical garden at Cal- 

 cutta, where a solitary plant has long been, is uncertain. It 

 flowered there for the first, and, so far as is known, the only 

 time, in 1813, in the hot season ; the tree being about eight feet 

 high ; and ripened a single legume in September. 

 Trunk arborescent, erect. Bark gray, smooth. Branches spread- 

 ing, dichotomous, drooping towards the extremity. Leaves 

 alternate, pinnate, two-paired. Leaflets obliquely' elliptic, fal- 

 cate, wavy, polished: 4 — 5 inches long; 2 — 2^ broad. Pe- 

 tioles swoln at the base ; upper edge channelled. Stipules none. 

 Cort/mbs terminal, compound ; primary ramifications dichoto- 

 mous. Pedicels articulate : upper part gibbous, fistular. Flow- 

 ers white, inodorous. Bractes none. Perianth four-leaved. 

 Leaflets round, concave, downy. Corol irregular. Petal one, 

 vcxilliform, round-cordate, wav}'. Claw linear, downy on both 

 surfaces. Wings and Keel none. Filaments nine : three anthe- 

 riferous, filiform, thrice as long as the corol, incurved : six ste- 

 rile, (a pair on either side of the vexillum, and solitary ones al- 

 ternating with the fertile;) less than a quarter of tlie length of 

 the fertile ones : all united at the very base, and free above, 

 dark chesnut-coloured, beset towards the lower end with thinly- 

 scattered white hairs : tips of the sterile filaments hooked, white. 

 Anthers linear, incumbent. Ge77« linear-oblong, compressed,
