floribus breviter pedicellatis ; $ racemo paulo breviore^ ramis 
1-3-floris, divaricatis ; drupis uviformibus, breviter stipitatis,

The branches are slender, less than a line in diameter, with 
internodes of 3 inches; the leaves are 5 inches long from 
base to apex, or 4| from basal sinus to apex, and 3^ inches broad, 
on a slender petiole 4 inches long ; the 6 raceme is slender, 
5-7 inches long ; its branchlets, 3 lines long, bear one to three 
flowers, which in bud are 1 line in diam. ; the fructiferous slender 
raceme is 4 inches long; its filamentous branches, 2-4 lines 
apart, are 2-4 lines long ; the pedicels, 3 lines long, bear generally 
a single oval drupe f inch long; the putamen (very much com- 
pressed) is 6 lines long, 4 lines broad.

This is the only South- American form, as Calycocarpum is the 
sole Norih- American genus, of the Heteroclinieae hitherto known, 
all the other eleven genera of this tribe belonging to Asia or 
Africa, The plant on which this genus was established was 
found by me in the Organ Mountains as far back as 1828, and 
again in 1837, but only in fruit; this enabled me to ascertain 
its peculiar carpological structure — an investigation that after- 
wards led me into an examination of the w^hole family. In 1845 
my son sent me, from nearly the same locality, an imperfect 
specimen of another plant, which, from the similar form of ita 
leaves and petioles and the structure of its flowers, appeared 
like a male species, and accordingly, in my “Notes on Meni- 
spermacese,’’ in 1851, I alluded to it under this belief; for its 
floral parts, though in quinary numbers, presented the usual 
biserial arrangement of alternate sepals, and ten stamens, the 
outer five being quite free, with the same number of fleshy 
scale-like petals at their base, while the five internal sta- 
mens were monadelphous for half their length. This so far 
appeared to correspond with Coscinium, Chasmanthera, and Pse- 
lium, except in the number of its parts; but, as I had met with 
the number five in other genera, the whole structure seemed 
conformable with Menispermacece. It is true that I found an 
occasional flower w'htch, with a similar arrangement, presented 
the addition of a single l-cel!ed, 1-ovular ovary in the centre; 
but I had observed a similar occurrence in Anomospermum and 
Tiliacora. A more careful examination of tbe stem of the plant 
afterwards convinced me that it w'as not Menispermaceous, but 
a species of Jatropha, with occasional hermaphrodite flowers.
