quaque dichotomia, ramis ultimis spicatim pedicellatis ; floribus 
minutis; sepalis4, obovatis, hirsutissimis ; petalo cyatliifbrmi, 
piloso ; antbera 4-loba : racemis $ geminis, axillaribus, tomen- 
tosis, folio paulo longioribus, imbricatim bracteatis, rachi

The specimens are not in very good condition, and certainly 
bear no resemblance to C. Pareira-, they constitute a very distinct 
species, with decided differential characters, one of the chief pe- 
culiarities consisting in having the petal in the female flower very 
deeply cleft, but entire at the base, with a single point of inser- 
tion within the claw of the sepal : in this respect it differs from 
Dissopetalum, which has two distinct petals, with a wide interval 
between the points of their insertion : in the form and size of its 
leaves it approaches C. Orinocetisis. The leaves are 2-2^ inches 
long. If inch broad, on a petiole 2 inches long, which is in- 
serted 2^-3 lines within the basal margin. The ^ panicles, 
with capillaiy branches, are 9-12 lines long, 9 lines broad, the 
peduncle measuring 4 lines, the primary rays 3 lines, the secon- 
dary ones 1-2 lines, the solitary pedicel in the principal bifurca- 
tions being 2 lines long. The $ raceme is 2-3 inehes long, the 
bracts 6 lines in diam., diminishing upwards to a breadth of 
1 line ; the pedicels are 1 line long, the sepal the same length, 
the petals half that length.
