90 NATURAL HISTORY OF PLANTS. 
compressed oblong-falciform coriaceous pod. The seeds have winged 
edges and are surmounted by a sort of falciform blade, and contain 
within their coats a fleshy embryo thinly surrounded by albumen. 
The only known species of this genus’ is a large Brazilian tree,. 
Pouacapoua americana.

covered with rust-coloured down; its leaves are alternate impari- 
pinnate, and its flowers form a large terminal ramified raceme. 
The flowers of Zhylacanthus’ resemble those of Batesia : we find 
the same imbricated perianth, with the petals tapering towards their 
base ; the same androceum of ten stamens, with inflexed filaments ; 
the same central gyneceum, with a pauciovulate ovary. But the 
style is long and slender, revolute in the bud, and ends in a broad 
peltate stigmatiferous dilatation; and the flower, axillary to a caducous 
bract, is accompanied, as in the Amkerstiee,’ by two pretty thick 
lateral bractlets of nearly equal size, and which by touching edge to 
edge form a complete envelope to the flower-bud. They separate at 
the apex on anthesis to free the flower. The inflorescence consists 
of ramified racemes towards the end of the branches. 7. ferrugineus 
Tor., the only species of this genus at first known, is an unarmed 
tree from North Brazil, with alternate paripinnate leaves. 
Dicymbe corymbosa‘ is a small unarmed tree from North Brazil, 
with alternate pinnate leaves, and large pseudo-corymbose flowers, 
whose receptacle forms a deep inverted cone, lined with glandular 
tissue. On its rim are inserted four’ or five imbricated sepals, and
