is very slender, 2-5| inches long, the pedicels 1 line long, the 
sepals 1 line long ; the fructiferous raceme is 4-5 inches long, 
on a very slender rachis ; the pedicels divaricated, 5 lines long ; 
the putamen, compressed, 41 lines long, 2^ lines broad, is denti- 
culated at both extremities, as in the typical species, deeply 
hollow on the ventral face, and radiately striated on the margin, 
as Poppig describes his species. The structure of the seed is 
quite similar to that already detailed.

This species was found by Gardner growing among bushes. 
The leaves, though somewhat polished and deep green above, 
are covered with numerous minute tubercular hairs, scabrid to 
the touch ; they are 2 inches long from the summit to the point 
of insertion of the petiole, beyond which the basal lobes extend 
1 j inch, thus making the leaves altogether inches long and 
3 inches broad, the petiole being about inch long. The spe- 
cimen is without flower or fruit.

folds late cordatis, acutiusculis, sinu baseos profundo, sub- 
7-nerviis, membranaceis, ciliatis, supra nitidis, subtus prse- 
sertim in nervis pubentibus ; petiolo longo, cinereo villosulo. —

The above characters, given by Von Martins, when thus trans- 
posed, render the diagnosis more intelligible : a plant, the root 
of which is sometimes parasitic and filipendulous, cannot be an 
erect shrub. The tuberous kind of root here described is like 
that known in the East Indian genus Tinospora, of which Odon- 
tocarya is the representative in the New World. The form and 
membranaceous texture of the leaves accord with no other 
Brazilian genus ; and it seems nearly allied to the last-mentioned 
species.
