68 SCHOMBURGK’S GUIANA PLANTS. 
specimen before me belongs to T. ovata, or T. montana, or 
whether it may not be distinct from both, not exactly agreeing 
with éither in foliage. 
Gardner's n. 1537, from Ceará, is a new species allied to 
T. myriantha, but distinguished as follows :—T. pubescens, 
foliolis: 6—9 lato-ovatis obtusis retusisve coriaceis supra - 
glabris nitidis, subtus ad nervos petiolis rachi et ramulis fer- 
rugineo-pubescentibus, cymis axillaribus paniculatis multi- 
floris.—This is the first, out of hundreds of specimens of - 
various species, in which I have seen the young fruits with the 
flowers that produce them. I now perceive that I was mis- 
taken in considering the genus as unisexual, the fertile flowers 
. being precisely similar to those which from their constant 
abortion I had considered as males. 
- M. Guillemin has ascertained that it is chiefly the several 
species of Trioptolemea, which are known in Brazil under the — 
name of Jacaranda, and furnish the Rosewood of our cabinet- 
makers. 
Of the genera Miscolobium and Platymiscium, Y have as ye * 
seen no Guiana specimens; but it is probable they may both 
be hereafter detected in that country, as the former has an $ 
extensive range in Brazil, and is also found in tropical Africa, - 
from whence M. Guillemin has communicated to me three 
 Senegambian species; and I have seen Platymiscia, generally | 
very bad specimens, from the West Indies, as well as from - 
various parts of Brazil. Vogel’s genus Platypodium (Callis- 
ema of my memoir), appears to be confined to Brazil. : 
183. Deguelia scandens, Aubl. Pl. Guian. Yl. p. 150. t. 300. 
DC. Prodr. Yl. p. 422, —On the high banks of the Quitaro- 
Schomburgk, n. 564.— These specimens, being in flower : 
only, cannot further elucidate the affinities of the genus. I 
have however a specimen with ripe fruit gathered by Mr — 
Parker in Demerara, which has so nearly the foliage and in- —— 
florescence of Aublet's plant, that although perhaps specifi- - 
. cally distinct, it appears to be a congener; and if that be the — - 
case, Deguelia is scarcely to be distinguished from my. t: JS 
section of Andira.
