I collected specimens of this plant in 1836 in a wood on the 
borders of JmnijubaBay, in the harbour of Bio de Janeiro : it 
was found also by Gardner on the maritime skirts of the Corco- 
vado range at Tejuco, and by Padre VeUoz in the maritime woods 
at Tagoahy, in the same province : the specimens collected by 
Moricand in Ilheos, no. 2347, do not appear to me to differ spe- 
cifically from the others. It forms a tree with spreading branches, 
of which the branchlets are aeutely angular as above described. 
Its leaves are 6 inches long, 2^ inches broad, on a petiole f of 
an inch in length : the panicle is from 2 to 3 inches long, ivith 
its branches spreading at right angles to the length of inch : 
the flower-bud is oval, 2 lines in length ; the petals are of a 
greenish yellow colom’, clothed inside with long white silky hairs, 
which become browm in drying : the ovarium is in like manner 
sericeous, so that the lower half of the style, and its basal lobes, 
are concealed. As the name cordata may lead to mistake, there 
being nothing in the form of its leaves or other parts approxi- 
mating a heart-shape, I have dedicated the species to the author - 
of the genus ; — the somewhat truncated base of the kernel of the 
fruit (probably an accidental occurrence) suggested the above 
designation*. 
Mappia. 
This genus, described and figured in the ‘ Hortus Schoenbru- 
nensis ’ by Jacquin in 1797, appears to have escaped the notice 
of all succeeding botanists. The plant upon which it was founded 
was raised in the Imperial Botanic Garden, but the country from 
which it was derived was then unknown. There can be no 
doubt, however, that it is identical with the Icacina dubia of 
M‘^Fadyen, and that it is a native of Jamaica. I have also to 
* This plant, with full generic details, is shown in plate 7 at the end 
of this volume.
