Arbor 25-pec!alis, corona parvil. Flores 
semper octandri, suaviter odorati. I^etala 
alba, conduplicata, marginibus villo-sis. Sta- 
mina 4 sepalis, 4 petalis opposiia et his per

maxima, 2| pedalis, sul venucosa. 
This appears to differ from R.MangleofLin- 
neus, a native or the vvestern hemisphere, in 
the form of the leaves. The habit of these two 
species is very distinct, as is likewise the form 
of their anthers, 'fhefactof the fruit of R-ma- 
crorrhiza being pendulous, results of course 
from the greater length of the peduncle. This 
in R. Candelaria isso short, that thegermina- 
ting fruit, which is at first erect, subsequently 
becomes curved downwards by itsown weight. 
II. Kandelia. Wight and Arnott. 
Rhizophora § Kandelia. Dec. 
The character of the ovarium, as given by 
Wight and Arnott, is at variance with the 
usual structure of the order, and with my 
own observations. 1 have found it to have 
the ordinary structure.

with my plant, wliich is distinct from Rox-
