274 LEGUMINOS. ACACIA. 
in the suppl. pl. belongs to it: we think it the same as Roxburgh’s Mim. 
dumosa. The true M. cornigera was taken up by Linnæus from a figure, 
and without seeing a specimen: it is an American plant.—From some un- 
known cause, the tree at a certain stage ceases to elongate: the branches 
then increase horizontally to a considerable extent in all directions, forming 
a flat umbrella-like top: in one extensive jungle of it, near the foot of the 
Madura hills, every tree has assumed this remarkable form. 
* 846. (5) A. dumosa (W. & A.:) shrubby: branches terete, glabrous, 
armed; thorns numerous, subulate, stipulary, white, united at the base: 
leaves bipinnated, small; pinnæ 2-3 pair, with a hollow gland between the 
last pair ; leaflets about 4 pair, obovate-oblong, obtuse, glabrous, very small : 
spikes axillary, somewhat in pairs, peduncled, much longer than the leaves, 
many-flowered.—Mimosa latronum, Linn.! suppl. p. 438 (as to the spec. 
char.)—9M. dumosa, Roxb. fl. Ind. 2. p. 559. 
The fruit is unknown. 
$ 2. Unarmed : heads of flowers globose. 
+ Leaflets numerous, small. 
847. (6) A. stipulata (DC.:) arboreous, unarmed : young shoots irregularly 
angled, and the petioles tomentose: leaves bipinnated ; pinnze 6-20 pen 
with a gland on the petiole, and between each of most of the upper pairs ; 
leaflets numerous, very unequal-sided, semihastate, acute: stipules and the 
bracteas large, semicordate, acuminated : peduncles aggregated, panicled ; pa- 
nicles terminal and in the upper axils: heads of flowers globose : corolla tubu- 
lar, 5-cleft : stamens about 20, very long, monadelphous at the base : legumes 
flat, thin, linear-lanceolate, glabrous, 6-12-seeded.—DC. prod. 2. p. 469;

_In the Bengal plant the stipules are more persistent ; in ours they are - 
ciduous, although the bracteas remain on for a long time: we can, however, 
see no other difference. We can point out no character between this and 4.

848. (7) A. amara (Willd. :) arboreous, unarmed : branches terete ; IUE 
shoots, petioles, peduncles, and under side of the leaflets, clothed with y el- 
lowish tomentum: leaves bipinnated ; pinnze 8-10 pair, with a gland on the 
petiole and between the last pair; leaflets 20-30 pair, when old somewhat 
glabrous: stipules laneeolate : peduneles solitary or aggregated, long and fili- 
form, in the axils of the upper leaves, and racemose from the abortion of the 
leaves: flowers small, in globular heads: corolla 5-cleft: stamens long, nu- 
merous, monadelphous: legumes flat, thin, broadly linear, 3-6-seeded.—

Our specimens are from Klein’s herbarium, and were named “ Mim. to- 
mentosa, Willd.,” a circumstance the more remarkable, because it was from 
Klein that Willdenow had his specimens of the true A. tomentosa. 
849. (8) A. Wightii (Graham:) arboreous, unarmed: branches terete; Y oung 
shoots nearly or quite glabrous: leaves bipinnated ; pinnee about 9 or 10 pat 
with a gland on the petiole below the lowest pair and between the upper bs 
pair; leaflets 15-25 pair, oblong-linear, obtuse, glabrous, glaucous on t 
under side: petioles pubescent: stipules subulate: peduncles solitary; 6- 
bearing a capitate head of flowers: legumes thin, broadly linear, about 
seeded.— Grah. ! in Wall.! L. n. 5259; Wight! cat. n. 592, 595.—Mimos*
