266 LEGUMINOS E. DALBERGIA. 
820. (9) D. frondosa (Roxb. :) arboreous: bark smooth: leaflets about 5 
pair, cuneate-oval, emarginate, when very young silky, afterwards glabrous 
or sprinkled on the underside with a few hairs: panicles axillary, pubescent ; 
flowers secund, racemose along the ultimate branches of the panicle: calyx 
hairy ; two upper segments obtuse, lower ones more acute, lowest the nar- 
rowest and longest: vexillum with a large callosity at the base of the limb; 
ale as long as the vexillum, about twice as long as the keel: stamens equally 
diadelphous: ovary very slightly pubescent: legume lanceolate, 1—4- (usual- 
ly about 2-) seeded.— Roxb, hort. Bengh. p. 535 fl. Ind. 3. p. 236 ; DC. prod. 
2. p. 417 ; Wall.! L. n. 5855 ; Wight! cat. n. 918, 921.—D. arborea, Heyne 
in Roth, nov. sp. p. 330; DC. l. c. Courtallum. Travancore. 
Dr Wight’s two numbers are very different in appearance. No. 918. has 
the leaflets approximated and is in fruit, but is obviously taken from an older 
pant of the tree; it is from Travancore: n. 921, from Courtallum, is in 
ower only, and corresponds with D. arborea of Heyne; it has the leaves 
tender, and the leaflets more distant; the specimens have been apparently 
taken from young shoots, and have a drooping aspect. Dr Wallich conjoins 
both. We have some doubts, judging from the description, if D. lanceolaria, 
Linn., be not this very species ; the leaflets, however, are said to be hirsute: 
it is only yet known as a Ceylon plant, the Malabar station being taken from 
Rheede, whereas Rheede’s plant is D. seandens. 
821. (10) D. spinosa (Roxb. :) shrubby, erect, glabrous: ultimate branches 
distichous, horizontal, rigid, and almost spinescent: leaves fascicled ; leaflets 
3—4 pair, alternate or nearly opposite, very small, elliptic or cuneate-oblong, 
retuse : racemes fascicled, secund, recurved, glabrous: calyx glabrous; seg- 
ments oblong, obtuse: vexillum longer than the keel and ale, without callo- 
sities: stamens equally diadelphous: ovary stalked, 4-ovuled.—Roab. fl. Ind. 
3. p. 233; Wight ! cat. n. 798.—D. horrida, Graham in Wall. L. n. 5877. 
xburgh says the legume is oval and l-seeded ; we have not seen it, and 
as Dr Wallich feels uncertain that ours is the same with Roxburgh’s plant 
(from Chittagong), we have derived the above specific character from the 
specimens before us alone. 
LXHI. PTEROCARPUS. Linn.; Lam. ill. t. 602. 
Calyx 5-cleft, somewhat bilabiate. Corolla papilionaceous, glabrous: 
keel-petals distinct or slightly cohering. Stamens 10, variously combined. 
Ovary long-stalked’ Legume indehiscent, irregular, somewhat orbicular, 
surrounded by a wing, woody and often rugose in the middle, 1-3-celled. 
Seeds solitary in each cell, reniform.—Unarmed trees or shrubs. Leaves Wn- 
equally pinnated. Racemes axillary or forming terminal panicles. 
822. (1) P. santalinus (Linn.:) arboreous: leaflets 3 (rarely 4 or 51) 
roundish, retuse, glabrous: racemes axillary, simple or branched: pe 
long-clawed, all waved or curled on the margins: stamens triadelphous 
(5, 4, and 1): legume stalked, 1-seeded ; the wing somewhat membrana- 
ceous, waved.— Linn. suppl. p.318 ; Willd. sp. 3. p. 906 ; DC. prod. 2. p. 419; 
Spr. syst. 3. p. 192; Wall.! L. n. 5844; Wight! cat. n. 908.—— Paulghaut 
mountains ; Koenig. 
We have never seen more than 3 leaflets: the specimens with 4 or 5 may 
belong probably to the next species. 
, 823. (2) P. marsupium (Roxb.:) arboreous : leaflets 5-7, alternate, ellip- 
tical, usually deeply emarginate, glabrous: panicles terminal: petals 1 
clawed, all waved or curled on the margins : stamens combined into a sheath, 
split down to the base on the upper side, and half way down on the lower : 
legume long-stalked, surrounded by a broad membranaceous wing; obtuse r 
the base, 1- or rarely 2-seeded.— Roxb. Cor. 2, t. 116; ft. Ind. 3. p. 234;
