Perhaps in strict justice the specific name (rugata) given by Lamarck 
ought be retained. As to the genus, we have some doubts if it ought to be 
left in Acacia; but the legume being dehiscent and the valves not jointed, it 
cannot be placed in Mimosa. A. rugata, Wall. L. n. 5251, is very closely 
allied, and has precisely the same kind of legume. se 
862. (21) A. cesia (W. & A.:) shrubby, diffuse, armed with numerous 
scattered small prickles: leaves bipinnated ; pinnæ 10-14 pair, with one or 
two convex oblong or roundish glands on the petioles and one between each 
of the last 3—4 pairs; leaflets 15—40 pairs, oblong-linear, somewhat falcate, co- 
riaceous, glabrous and shining above, pale and pubescent (or at length near- 
ly glabrous) beneath : panicles terminal: heads of flowers globose, numerous: 
stamens numerous, distinct: legume linear, flat.— Wight! cat. n. 573, 585.—

We have not seen ripe fruit; in our specimens the legumes appear as if 
they would be of a thickish texture and narrow linear; we therefore quote 
M. pennata of Roxburgh's drawings (not of the fl. Ind.) and M. cesia of the 
fl. Ind. with doubt, as he represents the legume broadly linear, and thin. M. 
tenuifolia is omitted by Roxburgh in the fl. Indica ; perhaps he meant to re- 
unite it with his M. cæsia—Linnæus has misled all his followers by quoting 
Pluk. t. 330. f. 3, in place of f. 1, although he refers correctly to the letter- 
ress from which the name cæsia was derived: and to add to this error, he 
taken his character from a specimen of A. Zntsia, not in the least like 
either figure. In his Species Plantarum, he established his Mim. Zntsia from 
Rheede's figure, and of course characterised it in nearly the same terms as 
his M. cesia. 
863. (22) A. Intsia (Willd. :) shrubby, diffuse, procumbent or climbing: 
branches angled, armed with numerous small recurved prickles: leaves bi- 
innated ; pinnz 5-8 pair; leaflets about 9 pair, linear-oblong, shining, gla- 
rous: petioles armed with recurved prickles on the under side, with a large 
convex gland near the base and a small one between each of the 1-3 last pairs 
of pinn : panicles lage, terminal ; peduncles 3-4 together : heads of flowers 
lobose : corolla 5-cleft : stamens numerous, distinct : legumes broadly linear,

The figure by Plukenet, from which the species has been taken up and all "e 
synonyms depend, exhibits the leaflets (at a) much larger than in our plan " 
we have, however, referred them here rather than to Prosopis specige™@, 1 
the supposition that the bodies he has represented at the base of the pono 
may have been stipules. The only specimen we have seen is very imperieC
