I. Schrankia aculeata. Willd. — DC — Schkcht. in Linn. 5. p. 593. 



1. Prosopis horrida. Kunth, Mini. p. 1 16. t. 33. 



The spines in our plant are strong, about an inch in length. 



1. Acacia JiUcina? Willd.— DC— Mimosa filicioides. Cav. Ic. \.t. 78?— Hab. Talisco. 



2. A. revoluta. Kunth, Mini. p. 34. t. 26. 



3. A. Acajmlcencis. Kunth, Mini. p. 78. t. 24. 

 Leaves only of this plant are in the herbarium from Acapulco. 



1. Brongniartia glabrata ; foliolis 3-4-jugis lato-ellipticis obovatisve retusis mucronatis 

 supra ramisque glaberrimis subtus (oculo armato) minutissime pubescenti-scabris, stipulis 

 nullis aut deciduis, carina maxima. 



In general habit this species very much resembles the B. podalyrioidcs of H. B. K. t. 588 ; but the leaflets 

 are fewer and almost entirely glabrous, the stipules are wholly wanting or they soon fall away, and the carina 

 is remarkably large in proportion to the rest of the flower. There can be no doubt of its belonging to this 

 genus, which again, perhaps, as De Candolle suggests, should be united with Peraltea of H. B. K. 



1. Caesalpinia exostemma ? Fl. Mex. Ic. ined. DC. Prod. 2. p. 483. 



1. Cassia puberula? H. B. K. Nov. Gen. 6. p. 341. 



Our specimens have no perfect flowers, and no fruit. The leaflets are many of them 4 inches long. 



2. C. pauciflora ? II. B. K. Nov. Gen. 6. p. 360. 



If ours be the true plant, it is glandular and viscid in every part, very woody, with much branched stems. 

 Leaves copious. Leaflets obovate. Racemes few-flowered, reddish-orange coloured. Legumes oblongo- 

 lanceolate, compressed, hirsute or almost hispid, 1 -celled, about 5-seeded. 



3. C. fabaginifolia. H. B. K. Nov. Gen. 6. p. 363. — DC. — Hab. Talisco. 

 1. Bauhinia Lunaria. Cav. Ic. 5. t. 407. — Hab. Acapulco. 



Obs. We are obliged to omit the insertion of two other species of Bauhinia, and several Leguminosa, 

 on account of the very insufficient specimens. 



Ord. XXX. ROSACEA. Juss. 



Of this Order there are two species in the collection, but both appear to have been placed there by acci- 

 dent, and were probably gathered at Loo Choo or Bonin. One is Photinia serrulata, Lindl., a variety with 

 oblong-obovate rather obtuse leaves, the serratures of which are bluntish, and may almost be called crenatures. 

 The other is our Rhaphiolepis integerrima ; but in the specimen now before us, although many of the leaves 

 be quite entire, others are crenato-serrated. This appears, therefore, to be Crataegus lavis of Thunberg, 

 which is usually considered a Photinia, but has certainly not the calyx or fruit of that genus. 



Ord. XXXI. LYTHRARIE^E. Juss. 



1. Heimia salicifolia. Link et Otto. — Neessea salicifolia. H. B. K. Nov. Gen. 6. p. 192. 

 From this we scarcely think that H. siphilitica, De Cand., specifically differs.
