differs from it in its introrse 4-lobed anthers, the want of petals, 
the greater number of its sepals, and in the character of its in- 
florescence. Detandra is distinct from it in its anther-cells, a

its peltate leaves, with another kind of venation. Sarcopetalum 
also differs in the number and form of its sepals, and in the 
globular shape of its larger fleshy petals.
