This species has .long been represented in a fragmentary 

 form in the Kew herbarium, and the specimens which allowed a 

 description to be drawn up were recently communicated by 

 M. Chevalier. The following interesting field note accompanied 

 the specimens: '^ Petit arbre de 12 m, a 20 m. de haut; tronc de 

 5 m. a 8 m. sans branches et de 15 cm. a 35 cm. de diametre. 

 Ecorce brune s'enlevant en plaquettes epaisses. Les feuilles 

 tombent a la fin de la floraison, Fleurs blanches, se detachant 

 facilement et jonchant le sol en quantite au moment de la floraison. 

 Nom. vera. Dianbalaka (Kassonkes du Senegal). Interieur du 

 Senegal: croit en assez grande abondance a travers les savanes 

 incendiees annuellement de la province du Niani-Ouli et dans le 

 sud du Bondou.^^
