ner, 1445 bis). 
This is easily distinguished from all its allied species by its 
very long and erect petioles, geniculated upon very rounded 
leaves ; its petiole approaches that of the following species, but 
is longer and palately (not peltately) fixed upon the blade. The 
root is nodose, sometimes throwing out two stems : these are 
erect, 15-20 inches high, and 1^ line thick; the leaves, in the 
S , are 1-3 inches apart, 1^-2 inches long, 1|— IJ inch broad, 
on a somewhat slender, very erect petiole 10-15 lines long. 
The very slender peduncles, about 6 lines long, have three alter- 
nate branches 3 lines long, each bearing a head of subcorymbose 
minute flowers. I have referred here the C. ebracteata of St. 
Hilaire as the $ plant of this species, as it agrees in the form of 
its leaves, their tomentose covering, and in the greater length of 
their petiole. This plant differs from all others of this section 
in the absence of the usual raceme-like $ inflorescence in the 
axils of its leaves; the pedicellated flowers are fasciculated at 
the origin of the petioles of the superior leaves only, just as they 
are placed in the axils of what are considered bracts in the ordi- 
nary raceme ; and in this point of view the $ inflorescence here 
is a terminal raceme, with leaves instead of bracts. We find this 
occurring also in C. Amazonica ; but in that species there is at 
the same time a superabundance of the ordinary flowering ra- 
cemes, there being three in each main axil instead of the ordi- 
nary single one : a similar mode of $ inflorescence is found in 
C. mallophylla. The leaves are orbicular oval or broadly elliptic, 
subacute, cinereo-tomentose beneath, 2^ inches long, 2 inches 
broad, on a slender petiole 6 or 8 lines long; the pedicels are 
H line long; the spathulately oblong sepal, pubescent outside, 
is j line long ; the minute orbicular petal, one-fourth of that 
length, is scarcely visible.
