5. Chasmanthera. 
The typical species collected by Schimper in Abyssinia was 
named Chasmanthera dependens by Hochstetter, who gave an im- 
perfect description of the genus in the ‘ Ratisbon Flora ’ for 1843. 
This plant has a very peculiar habit, having large orbicular cordate 
hairy leaves, on long petioles, and a very elongated slender 
simple raceme. It belongs to the tribe Heterocliniece, as shown 
by the structure of its fruit : its putamen is oval, compressed,
