247. A. Sieberiana (DC. Prod. ii. 463), ramulis junioribus 
petiolisque subtomentellis mox glabratis, spinis rectis demum 
eburneis, pinnis 10-30-jugis, glandulis scutellzeformibus pau- 
cis, foliolis 20-40-jugis oblongo-linearibus obtusis glabris supra

248. A. Nubica (sp. n.), ramulis petiolisque albidis molliter 
non, spinis brevibus validis rectis, pinnis 6-10-jugis,

dofan ?) Kotschy n. 407 ofthe Un. Itin.—This species re- 
sembles in many respects 4. Adansonii, and Æ. Sieberiana, 
but the branches, and even the spines, are more downy, 
and the bracts are much below the middle of the pe 
The pod is unknown to me. 
249. A. planifrons (Wight. et Arn. Fl. Penins. Ind. Or. i., 
276), subglabra, spinis brevibus recurvis v. longis rectis subula-

250. A. Hozburghii (Wight. et Arn. Prod. i. 276), or 
Mimosa eburnea Roxb. Pl. Corom. t. 199, non Linn., which I 
have not seen, appears closely to resemble A. planifrons, 
but to differ in the less tumid pod.
