The branches are terete with a smooth bark; the axils are 1^ 
to 2 inches apart ; the leaves are quite smooth, thick, and coria- 
ceous, 8 inches long, 2^ inches broad, on a petiole of i to | inch 
iu length ; a raceme about li inch long springs out of each axil, 
sending out from the base upwards several alternate branches at 
nearly right angles, which are again divided; the branchlets and 
pedicels are slightly pubescent and furnished at their base with 
a shoi’t, obtuse, fleshy bract, covered with short fine hairs ; the 
ovarium is 4 lines long, 1| line diameter ; the stigmatiferous disk 
is about one-third of the diameter of the ovarium ; the calyx and 
petals are quite glabrous; the latter are linear, submembranaceous, 
marked with three parallel nervures, and are of a reddish -yellow 
colour when dry*. 
Emmotum. 
This neglected genns was proposed by Desvaux in 1825 upon 
a plant from Guiana. By Endlicher it was referred to Leretia 
of the ‘ Flora Fluminensis,^ with which it neither accords in the 
appearance of the leaf nor the mode of its inflorescence : Hamil- 
ton's character as given in his ‘ Prodi’omus,’ notwithstanding its 
brevity, is snfficiently well marked to show that it does not difi'er 
from Pogopetalum, founded by ]\Ir. Bentham in 1840 ; indeed the 
Emmotum fagifolium, Desv., corresponds with Pogopetalum acu- 
tum, Benth., both from Guiana, so as to leave no doubt of their 
identity : according fherefore to the austere rule of science, the 
latter name must give way to the former. IMr. Bentham in 
establishing his genus recorded two species, and has since de- 
scribed two others, and I have now to add a fifth. All the spe- 
cies, which are from Guiana and intertropical Brazil, seem to 
form good-sized trees, with very thick coriaceous leaves of a 
peculiar appearance ; their inflorescence is in axillary crowded 
fascicles of rather small flowers, which are distinguished by 
having petals densely beset on their inner face with long red 
silky hairs arising from an elevated costal nervui-e. Their chief
