Ct. cordata, nob.—This curious plant was gathered by Dr. 
Krauss at Port Natal, and is No. 186 of his collection. It 
may take its place near Acalypha, but is abundantly different 
from that and every other genus with which I am acquainted. 
The singularly slender, almost cobwebby filaments, and the 
linear rigid anthers of the male flowers, with the curiously 
cut segments of the female perianth, are its striking charac- 
ters. The generic name is compounded of «res and pepis, 
in reference to the latter peculiarity. Some other new genera 
of Euphorbiacee are in my possession, but as my specimens 
are not complete I defer noticing them for the present. I 
may remark, however, that Phyllanthus verrucosus of Thunberg 
cannot be referred to that genus, having an uncertain number 
(5-6-7) of free stamens, springing irregularly from a number 
of glands which cover the bottom of the calyx without order. 
No. 468 of Krauss’s Herbarium is very near Microstachys, 
Juss, if it be not a species of that genus.
