Syn. — Spondias Lakonensis Pierre, Fl. For. Coch. t. 3756 (Sept. 1898). 



« This plant was made the type of a new section Allospondias of the genus 

 « Spondias by Pierre. The author, who did not know the fruit, remarked, 

 « however, that it differed in certain characlers from Spondias, and that it 

 « might have to be referred to a new genus when the fruit should be known. 

 « The Kew collections do not contai n complète fruits, but several stones (puta- 

 « mina) deprived of their fleshy covering, which is, according to Balansa, 

 « edible. The structure of those stones with their large cavities occupying the 

 «. angles and much wider than the seed-containing cells, with their considerably 

 « reduced stony substance, and the absence of the terminal pits so characteristic 

 « of Spondias, appear, in connection with the thin leaflets and their nervation, 

 « to justify the raising of the section Allospondias to generic rank. Dr. Pierre, 

 « to whose kindness we owe a spécimen of the type of his Spondias Lako- 

 « nensis, lias confirmed this view after having seen a sketch of the fruit which 

 « I had sent to him». (Stapf).
