gland between the pinne and between the pairs of leaflets: petiole shorter 
than the leaflets: flowers capitate; heads shortly peduncled, racemose, the 
racemes panicled: legumes turgid, twisted : seeds glabrous and smooth, im- 
bedded in a firm pulp.—Willd. sp. 4. p. 1005 ; DC. prod. 2. p. 436 ; Spr. syst.

Roxburgh says it was introduced into India from the Philippine islands ; 
it is now a tree of very frequent occurrence, particularly towards the coast. 
830.. (2) I. geminata (W. & A. :) shrubby: branches simple, pubescent, 
filiform, flexuose, with stipulary spreading spines: leaves conjugately pin- 
nated, with a gland between the pinne : leaflets 3-5 pair, with an odd one 
on the outside below the pairs, oblong-obovate, unequal at the base, gla- 
brous, without glands between the pairs: petioles pubescent: flowers capi- 
tate; heads small, globose, few-flowered, on axillary slender peduncles.—

Our specimen is from Ceylon, but we believe it has also been found in the 
Be provinces of the Peninsula. It forms a shrub from 8 to 12 feet 
igh. 
831. (3) I. xylocarpa (DC.:) arboreous, unarmed : leaves conjugately pin- 
nated, with a gland between the pinnee ; leaflets 2-4 pair, with an odd one 
on the outside below the pairs, ovate-oblong, acute, with a gland between 
each pair: peduncles in pairs, axillary, long : flowers globose-capitate : le- 
gume ovate-oblong, hatched-shaped, woody, many-seeded.—DC. prod. 2.

1832. (4) I. Koenigii (W. & A.:) thorns stipulary, stout, straight, very pa- 
tent : branches flexuose, and petioles and peduncles pubescent : leaves bipin- 
nated ; pinne 2 pairs, with an orbicular gland between the pairs; leaflets 4 
pair, with an odd one on each side below the lowest pair, obliquely oblong, 
mucronate, shining on the upper surface: peduncles axillary, in pairs, the 
length of the leaves, each with a single globular head of 8-10 flowers.—Mi- 
mosa nitida, Vahl, symb. 2. p. 103.—Acacia nitida, Willd. sp. 4. p. 1086; DC.

With this we are unacquainted. We have referred it to Inga from the 
pinne having a leaflet more on the outside than on the inner, a peculiarity 
unknown, we believe, in Acacia: it has no relation. with I. nitida, Willd. 
May it not be an accidental variation of I. geminata with 2 pair of pinnee ¢ ; 
every other character agrees very exactly. Vahl received it from Koenig. 
833. (5) I. bigemina (Willd. :) arboreous, unarmed : leaves conjugately or 
bipinnated ; pinnæ 1-2 pair, with a gland between each pair; leaflets = : 
pair, short-petioled, ovate-lanceolate, acuminated, glabrous, shining, ud 
a gland between each pair: racemes panieled, terminal, many Howes ; 
flowers in small globose heads: legumes spirally twisted.— Willd. E ; 32
