of Marcgraaf and Piso. It differs from G.fastuosa in its terminal congested raceme 

 laro-er flowers, winged ovary and fruit, both crowned by 6 broadly triangular sepals.

its leaves are 4-6 in. long, l|-2-2- in. broad, on a petiole 3-4 lines long, with about 12 

 pairs of nerves ; the pedicel is 1 in. long ; the ovary is 3 lines long, not costate, as Berg 

 affirms, crowned by a short ring formed by the united sepals, which are 3 lines long ; tlie 

 petals are 6-10 lines long, 4-6 lines broad ; the fruit is globular, greyish, smooth, U 

 lines in diam., by abortion 4-5-locular, each cell containing a single oval seed 9 lines 

 long, 4 lines broad, suspended by a thick fleshy funicle of equal length. 



This species was established by "Willdenow upon the materials furnished by Aublet. 

 Dr. Berg was quite unjustified in confounding it with another very distinct species, well 

 figured and described by Poiteau [G. pterocarpcC) : its chief distinguishing features 

 are its alternate flowers, their smaller size, the acutely 6-lobed limb of tlie calyx, 

 the wings of the ovary vanishing at base, and its much smaller smooth greyish fruit

by abortion 4-5-locular, with monospermous cells. Berg's diagnosis of the species is 

 therefore rejected, and its characters are remodelled above, in unison with Aublet s 

 materials.
