This evidently belongs to the esculent group of Manihots, of 
which the Jatropa Manihot, Linn., may be considered the type- 
Dr. Graham has referred it to the Janipha Leeflingii, Humb. 
(Jatropha Janipha, Linn.) ; yet I think it has no real connexion 
with that species; and I was myself rather disposed to look 
upon it as a var. of the real Manihot (figured in Bot. Mag. Tab. 
3071.) But I now possess several native specimens, all from 
the same locality, and I have seen various cultivated ones 
raised from seeds, gathered on the Parana, and these retain- 
ing all their peculiarities, that I am rather disposed to consider 
it a distinct and a new species. At the same time, it is very 
difficult to define the essential characters. It is scarcely neces- 
sary to compare it with any but Manihot Api, Pohl. (Jatropa 
Manihot. Linn.), M. utilissima, Pohl, (equally the J. Manihot, 
Linn., for they seem to differ only in the poisonous or inno- 
cuous qualities) and the M. flabellifolia. From all these our 
plant differs in the more flaccid habit, in the more numerous 
segments of the leaves, in the entire absence of purple on the 
petioles and nerves and flowers, in the much greater size of the 
perianth, which, both in the male and female flowers, are pale 
yellow green, with two red streaks in the middle of each segment. 
The eye distinguishes the species at once even in the dry state.
