We can by no means agree with M. Richard in uniting 
this species with the preceding. To us they appear to be 
abundantly distinct at all ages, and we have formed this 
opinion from an extensive series of perfect and imperfect 
specimens of both kinds. Turners figure of F. Phyllanthus 
is certainly drawn from a very much battered individual, but 
it is sufficiently like the plant in its perfect state to be recog- 
nised without much difficulty. We have seen many speci- 
mens similar to it, and possess others from more perfect indivi- 
duals where the frond is young and vigorous; but all are 
alike characterised by having the denticulate margin fringed 
with the racemose receptacles along the whole course of the 
leaf-like branches, which resemble in a very striking manner 
the phyllodia of a Phyllanthus (Section Xylophylla) to which 
Turner compares them. These fruit-bearing branches are 
not, as Richard supposes, denuded of leaves, but perfect, and 
indeed the youngest part of the frond.—As to F, Maschalo- 
carpus, Turner’s figure and description are only defective in 
not representing vesicles, which are often absent and were 
wanting on his specimens. Some of ours produce them. 
When present they are solitary, elliptical, large and apiculate, 
or tipped with a leafy point, and they occupy the place of the 
receptacles, namely, the axils of the distichous leaves. But, 
vesicles apart, C. Maschalocarpus is abundantly different from 
C. Phyllanthus. It is a much coarser plant, of a thicker and 
more opake substance ; its clusters of receptacles are densely 
fasciculate, not racemose, and they are invariably placed in
