margins, concave, suborbicular, acute at the apex, and imbri- 
cated ; they are adnate upon an externally pilose deeply 5-lobed 
fleshy torus : the petals are elliptic, with an internal carinated 
nervure, three times longer than the sepals; the stamens are 
two-thirds the length of the petals, and as long as the ovary and 
style, which are quite glabrous*.

This and the following species are vei’y dissimilar in appear- 
ance to any of the preceding, bearing somewhat a resemblance 
to the genus Leretia ; but their floral structure is quite in accord- 
ance with Villaresia, and some have the same porous glands in 
the axils of the nervures that characterize the genus. The leaves 
are 7^ inches long, 3^ inches broad, on a petiole 10 lines long : 
the radiating divisions of the inflorescence, in my specimen, 
are 2 inches long ; but as they are in a young state, they pro- 
bably would be double that length when fully matured; the 
lateral branchlets are 1 line long, quite patent, and bear three or 
five sessile flowers at their apex : the flower expanded is 2^ lines 
in diameter ; the sepals are obovate, somewhat acute, imbricate, 
and pilose ; the petals are laueeolate-oblong, neai'ly three times 
as long as the sepals, with a prominent internal keel ; they are 
imbricated in aestivation, with their apices inflected : the stamens 
are three-fourths the length of the petals, and longer than the 
pistil : the ovary is obovate and pilose, 1 -celled, with two sus- 
pended ovules t-
