description, in which respects the plants I have referred to that 
species tally admirably. Dr. Eichler gives a correct sketch of 
the $ inflorescence ; but he does not seem to have noticed the 
existence of flowers intermixed with ? and their preponderance 
in the same fascicle, which is not surprising where the flowers 
are so very minute. There is something unusual in the incised 
state of the petal in the male flower, though it is sometimes en- 
tire ; but the condition of the $ flower is altogether abnormal, 
where four pilose scales form the external envelope, appearing 
like four distinct sepals; but I have considered only one of 
them to be the sepal, and the three others encircling bracts : the 
petal, always open on one side and sometimes entire, is fre- 
quently incised into two, three, or four segments, which do not 
extend to the base. This species has many points of resemblance 
to C. andromorpha, but is certainly very distinct. The leaves 
are inches long, 1|-3| inches broad, on a petiole lf-2^ 
inches long. The rachis of the racemes is 6-8 inches long, 
with axils 4-6 lines apart, and the branches, when present, are 
1^ inch, diminishing to 3 lines in length; the peduncles 2-3 
lines long, with branches half that length; the pedicels f line 
long; the sepals cuneately oblong, 1 line long, with hyaline 
margins, and dark in the middle, with glandular patches ; the 
turbinate petal is I line long, with the stamen included. In the 
2 raceme the rachis is stouter, shorter, about 2^ inches long, 
with branches about 4 inch long, the petiolulated leaf-like bracts 
being about 2 lines long.

A very distinct species, with large orbicular leaves, somewhat 
like those of C. Caapeba, but differing in being more glabrous, 
of thinner texture, otherwise shaped at base, with a more slender 
and longer petiole : it is very dissimilar in its peculiar inflores- 
cence, both S and ? . The leaves are 3-4 inches long, 2|- 
4| inches broad, with a basal sinus, in the ^ , 3-5 lines deep;
