No Inga, hitherto described, appears to agree with this, which has also been sent us by Mr. Millett. The 

 petiole is quadrangular, the pinna? being inserted on each side of the upper angle, on the sharp edge of 

 which, therefore, are seated the glands. The leaflets resemble those of what we possess under the name of 

 I. fagifolia. 



3. Inga bigemina ? inermis, foliis conjugato-pinnatis, pinnarum foliolis 3-4-jugis oblongo- 

 lanceolatis supra nitidis, glandula sessili ad medium petioli communis et inter omnia foliola, 

 unica pedicellata in dichotomia, florum capitulis paniculatis, legumine torto. — Willd. Sp. 

 PL v. 4. p. 1007 ? 



If the figure of Rheede, Hort. Mai. 6. 1. 12, which is usually referred to, be considered a correct representa- 

 tion, then our plant must be a different species : our character is therefore drawn up from the specimens in the 

 Collection. Willdenow does not notice the gland about the middle of the common peduncle, otherwise 

 his description accords pretty well. Vahl, however, (Symb. 2. p. 103.) says, " glandula in petiolo communi 

 ad basin, partialium et inter singulum par pinnularum," which seems to imply that he had observed it. 



1. Acacia frondosa. Willd. Sp. PL v. 4. p. 1076? 



We have so named this on the authority of our friend Dr. Wight, the specimen in the Collection being 

 exceedingly imperfect. We have, however, quoted Willdenow with doubt, as the leaflets are smooth beneath, 

 and only pubescent on the margin, and as we have not been able to discover a gland between the lower 

 pinna;; but we observe glands between the lower leaflets. 



1. Caesalpinia Millettii ; pinnis 7-jugis, foliolis 15-18-jugis oblongis obtusis basi obliquis 

 subtus puberulis, aculeis parvis subtus inter pinnas, caule superne petiolisque dense pubes- 

 eentibus, panicula elongata, calyce glabro. 



Although we do not possess the fruit, we believe this species will be found to belong to the section 

 " Sappania." The specimen in the Collection is destitute of leaves,, and is only in bud, so that we have had 

 recourse to specimens sent long ago by Mr. Millett, after whom we have named it. 



2. Caesalpinia Chinensis?; pinnis bijugis, foliolis bijugis elliptico-oblongis utrinque obtusis 

 coriaceis glabris supra lucidis, racemis axillaribus pedunculatis recurvis, petiolo communi 

 ultra pinnarum par inferius sparse minute aculeato. — Roxb. Ft. Ind. 2. p. 361 ? 



Roxburgh's plant had not flowered, but he describes the stem as scandent, (a point we cannot determine 

 in the specimen in the Collection) and the " pinnai and leaflets of from two to three pairs." In the two or 

 three leaves in our specimen, they are constantly two pairs. It probably belongs to the section " Nugaria." 

 The leaflets are precisely as in C. Sumatrana, Roxb.
