Rhigiocarya racemifera, n. sp. ; — glaberrima, ramulis teretibus, 
striatis, cortice resiliente; foliis amplis, late oblongis, pro- 
funde cordatis, sinu rotundato, e medio angustioribus et gra- 
datim acutis, imo 5-nerviis, nervis teneribus, membranaceis, 
supra pallidis, subtus cano-glaucis, valde reticulatis ; petiolo 
tereti, striato, nitido, fuscescente, limbo breviore; racemo 
simplici, supra-axillari, glabro, petiolo longiore, pedunculo 
flexuoso, compresso, pedicellis fructiferis, simplicibus ; drupis 
uviformibus. — Ad fluv. Quorra, v. s. in herb. Hook. (Barter, 
n. 3325). 
The branchlets, twistedly striated, are 1| line in diam., some- 
what thicker at the nodes, where the bark scales ofFj the leaves 
are 6| inches long, or 5^ inches long from the sinus to the apex, 
and 5 inches broad, on a petiole 3^ inches long, which is tortuous 
at the base; the rachis of the raceme is 4^-5 inches long, 
flexuose, black, polished, marked from near the base with alter- 
nate cicatrices of the fallen pedicels, 2-3 lines apart ; pedicels 
3 lines long; drupes 8 lines long, 6 lines in diam.; putamen (in- 
cluding spines 1-1^ line long) 7 lines long, 5 lines broad; con- 
dyle roundly scutiform, very prominent, 4 lines long, lines 
broad. 
14. Anomospermum. 
The type of this genus is a scandent shrub which I found in 
the Organ Mountains in 1837 ; other species exist in Guiana 
and Northern Brazil. They have all oblong, stiff, glabrous, 
subcoriaceous leaves, sometimes reticulated, with rigid petioles 
articulated on the branch in a prominent cup. The inflorescence 
is in axillary racemes issuing from a hairy tuft a little above the 
petiole. The male raceme, in some species, is the length of, 
or longer than the leaf, its alternate branches bearing one to 
three flowers, or sometimes the inflorescence is reduced to a 
solitary pedicellated flower in each axil. The female raceme is 
much shorter and few-flowered. The flowers are of similar size 
in both sexes, measuring, when expanded, 2 or 3 lines in dia- 
meter : they consist of six fleshy sepals, alternate in two series, 
the outer three being much smaller and bracteiform ; they have 
six petals, also biserial, smaller than the inner sepals, rounded, 
extremely fleshy, the edges folded inwards so that each thus em- 
braces aud almost conceals a stamen fixed on its claw ; each fila- 
ment bears two small anther-cells half imbedded in its substance. 
A single sterile ovary is sometimes seen in the centre of the male 
flower, being columnar, somewhat ventricose, and terminated by 
a fungiform stigma : this I found of usual occurrence in the 
typical species, but I have not met with it in the few flowers
