After dehiscence of tbe anthers, 0"^'ing to the posterior cells, 

 which are slightly longer and broader than the anterior, becoming 

 flattened ont by the opening of the valves, there appears to 

 be a stont membranous terminal extension of the connective, but 

 this is no true appendage, and I believe that the case is similar 

 in Apeiha itself, in some species of which this appearance is very 

 marked.

A single specimen in the Ilookerian Herbarium, in fruit only, 

 collected by Mr. Barter in 1857, and described by him as a small 

 tree with long weak branches and showy white flowers belongs to 

 this genus, and may be a third species.
