Pterocarpus. DIADELPHIA DECANDRIA, 235 
tal, numerous, extending far. Leaves sub-bifarious, alter- 
nate, pinnate with an odd one, eight or nine inches long. 
Leaflets five, six or seven, alternate, elliptic, emarginate, firm, 
above shining, and deep green ;_ below less so, from three to 
five inches long and two or three broad. Petioles round, 
smooth, waved from leaflet to leaflet, five or six inches long, 
Stipules none. —Panicles terminal, very large, ramifications 
bifarious, like the leaves. Peduncles and pedicels round, a 
little downy. Bractes, a small caducous one below each di- 
vision and sub-division of the panicle. Flowers papilionace- 
ous, very numerous, white, with a small tinge of yellow. 
Banner with a long slender claw, very broad ; sides reflexed, 
waved, curled, veined. Wings with B ving as aboye, oval, 
waved, curled, veined. Keel two-petalled, adhering slight- 
ly for a little way near their middle, waved, &c. as the ban- 
ner. Filaments ten, united into one body near the base, but 
soon splitting into two bodies of five each, Anthers globose, 
two-lobed. Germ oblong, pedicelled, hairy, generally two- 
celled ; cedds transverse, and to the anterior margin the single 
oyulum of each cell is attached. Style ascending. Legume, 
the under three-fourths orbicular, the upper side, which ex- 
tends from the pedicel to the remains of the style, straight, 
the whole surrounded with a waved, veined, downy, mem- 
_branaceous wing, swelled, rugose, and woody in the centre, 
where the seed is lodged, not opening ; generally one, though 
sometimes two-celled. Seed solitary, kidney-shaped, 
From wounds in the bark, there issues a red juice, which 
hardens in the open air into a dark red, very brittle, gummy 
resin, on being powdered it changes toa light brown, not un- 
like powdered peruvian bark. Inthe flame ofa candle it burns 
with difficulty, and without cracking, swelling, noise, or any 
peculiar smell, into fine white chen In the mouth it melts 
away like the simple gums. Its taste is strongly, but sim- 
ply astringent ; asmuch so, | think, as that of the gum of the 
Butea, which it resembles much. It t Hinges, the Pius, but 
little ; heat does not soften it.
