"Habitat in Mindanao insula prope Samboangan" Cavanilles. 



Apparently not a Philippine plant; credited to South America in Index 

 Keuensis. 



Although the above four species described by Cavanilles are figured by him, 

 1 have seen no Philippine specimens that match his figures and descriptions. 

 As it is probable that the specimens on which the species were based were 

 not from the Philippines, I have enumerated them here as doubtful ones.
