With this plant botanists have confounded Cissampelos con- 
volvulacea, DC., Pericampylus incanus, and other Indian plants; 
in habit it bears a general resemblance to them. It appears con- 
flned to the islands of the Madagascar group. De Candolle 
states, on the authority of Thouars, that the leaves are peltate in 
the ^ and palate in the $ ; but this is contradicted by the 
drawings of the latter, and I have not found any such sexual dif- 
ference. They are almost as broad as they are long, inches 
in diameter, the depth of the basal sinus being from 3 to 5 
lines; the petiole is inches long in the and l|-2 inches 
long in the ? , and is inserted | line within the margin of the
