Anonesr a fine collection of Guiana plants in the herbarium 
of A. B. Lambert, Esq. there are several specimens of a plant 
with velvety branches, rigid pinnate leaves, and papilionaceous 
flowers; the calyx bilabiate with the limb reflected, its upper 
lip supporting the vexillum, being two-lobed, and the lower lip 
three-parted : the stamens ten, separate, dilated towards the base, 
and alternately longer: the style incurved and ciliate, bearing 
two truncated unequal stigmas, the uppermost of which is largest, 
and incurved towards the other. The germen is ovate and pu- 
bescent, containing five seeds; the fruit a short oblique woody 
pod, opening with two valves, and containing in general only one 
perfect seed, but is also occasiopally found with two: these are 
large, nearly oval, of a fine scarlet colour with a large black spot 
on one side. From these singular characters, noticed some time 
ago by Mr. Lambert, I was induced to examine some surround- 
ing genera of the order, to endeavour to discover its congeners, 
affinities, and proper place in the series; and a plant with similar 
scarlet and black seeds being enumerated in the Flora Guianen- - 
sis of Aublet, as a species of Robinia, but without.any further 
description, a reference to the Pseudo-acacia ingens, fructu coccineo,
