This is described by Aublet as a fine tree 50 feet high with a 
co])ious branching summit ; his original specimen, which exists 
in the British Museum, accords well with the drawing given in 
his work, only that the leaves being lower are somewhat larger ; 
they answer however with his description, being 7^ inches long, 
2^ to 3 inches broad, on a petiole of 3 lines.

Guiana Batava. — v. s. in herb. Hook, et Mus. Brit. Surinam 
[Hostman, no. 1209). 
This species appears to me distinct from the former, the leaves 
being much broader with a thicker and much longer petiole, and 
a more lengthened and more branching panicle; its leaves 
measm-e 6| inches long, 3^ inches broad, on a fleshy petiole | inch 
in length ; the panicle is 3|^ inches long, composed of many di- 
varicating branchlets*. 
3. Poraqueiba sericea, Tulasne, loc. cit. p. 172; — excelsa, foliis 
latissime ellipticis ve] ovato-ellipticis, basi rotundatis, vel ab- 
rupte breviterque in petiolum longum validum decurrentibus, 
apice mucronatis, supra glabris, subtus pilis minutissimis 
sericeo-pubentibus, nervis venisque prominulis; panicula ra- 
cemosa, axillari, cinereo-pubescente, folio breviore, floribus 
approximatis, minOribus, imo bibracteolatis, et cum pedicello 
bre\issimo articulatis, in alabastro ovato-globosis, petalis ovato- 
lanceolatis, imo 2-locellatis staminibus duplo longioribus, intus 
pilis brevibus patulis albo-lutescentibus vestita. — Brasilia 
aequatoriali, ad Egam Fluv. Nigri. (Popp. pi. no. 2597). 
The leaves of this species are much larger and proportionally 
broader than the former, being from 6 to 10 inches long, 4 to 
7 inches broad, on a petiole 1^ to 1| inch in length. The 
axillary panicle is from 4 to 6 inches long, and the flowers are 
barely 2 lines in length.

plate 10.
