leaves when pressed. It differs from Martynia not only in 
the presence of the two membranous bracts already men- 
tioned, but also in two of its stamens being abortive ; never- 
theless, as I see no particular necessity for separating it on 
these accounts, I leave it in the genus where it has hitherto 
stood. 
The drawing was made in September, 1836, from a plant 
raised by Mr. George Mills, in the garden of the late Mr. 
Rothschild at Gunnersbury.. It requires the treatment of 
a cockscomb, or any similar tender annual. 
Fig. 1. shews the form of the ovary, style and stigma ; 
2. is a cross section of the ovary, representing the two 
double revolute parietal placente ; and fig. 3. exhibits 
the two perfect stamens, the two imperfect ones, and the 
fifth, which is only rudimentary, all growing from the tube 
of the corolla.
