ancipitate, and almost winged, showing an approach to the 

 winged petiole. The name Arthrophyllum being preoccupied 

 by a plant of Blume, De Candolle changed the appellation to 

 what we have here adopted. Our garden at Kew owes the 

 possession of this rarity to that of Mauritius, where it has 

 been introduced by M. Bojer, and long cultivated. It flowered 

 with us in the month of August.
