fleshy connective bearing two oval separated anther-cells dor- 
sally adnate upon it, and each bursting introrsely by a longitu- 
dinal furi’ow. The position of the genus is yet quite uncertain. 
Dr. Eichler places it near Tinospora, probably on account of the 
resemblance of its leaves to those of Jateorhiza : it differs from 
it and all the genera of the Heteroclinea in having only three 
stamens ; in the monadelphous character of the stamens it re- 
sembles Chasmanthera, Parabcena, and Odontocarya, belonging 
to that tribe, which have six united filaments; while in its 
three monadelphous stamens it approaches Sarcopetalum, De- 
tandra, Syrrhonema, Rhaptonema, Desmonema, and Somphoxylon.

I have not seen this plant, which is very peculiar in its habit.
