of the others, (three inches in both ways,) and on a petiole 
half its own length, the lateral ones just above the middle 
of the common petiole, on short, partial footstalks ; common 
etiole from its base to the terminal leaflet full three inches 
Gi, channelled above. Stipules lateral, subulate. Ra- 
cemes a foot in length, terminal or axillary, branched. 
Flowers in pairs, on pedicels nearly as long as themselves, 
the panicle branching from between them, but many of the 
branches shewing no more than their terminal flower-bud. 
Calyx four-cleft, opposite ; Segments equal, ovate, subacute, 
concave, spreading, and on the outside, as well as the pe- 
duncle and pedicels, hairy. Corolla of an uniform delicate 
lilac colour, gaping ; vexillwm erect, flattish, subrhomboid, 
notched, faintly striated, and marked in the middle with a 
deeper purple spot, the lower part of which is green; un- 
guis inversely conical ; ban depressed, about as long as 
the vexillum, and nearly forming right angles with it, 
lower edges in contact in the anterior half, open behind, 
abruptly cut down to narrow, flattened, linear claws, which 
are continuous with their lower edges ; keel rather paler 
than the rest of the flower, and somewhat more distinctly 
striated, shorter than the wings, notched at its apex, and 
split from the base to nearly half its length, having two 
linear claws, above which it is gibbous on both sides, and 
adheres there to corresponding depressions of the wings ; 
it shuts the aperture between the claws of these, so as with 
them to give the form of a boat to the lower half of the 
flower. Stamens monadelphous, straight, being scarcely 
curved at their apices; anthers yellow. Germen long, 
linear, slightly hairy, indistinctly lobed ; style bent at right 
angles to the germen, conical, smooth ; sé¢gma terminal, 
small, cleft, in contact with the vexillum. 
This plant was brought to the Royal Botanic Garden, 
Edinburgh, in 1823, under the name here adopted, from 
the Botanic Garden of Calcutta, by Dr. Macwuirrer ; and 
it has flowered in the stove every summer since. The early 
fall of the blossoms, and the small number of them which 
expand at a time, are prejudicial to the beauty of this spe- 
cies ; but its raceme is large, the hue of the flowers beau- 
tiful, and the drooping branches are remarkably graceful. 
No fructification has been perfected. :
