“Habitat in Mindanao insula prope Saniboangan” Cavanilles. 
Apjiarently not a Philippine plant; credited to South America in Index 
Kewensis. 
Although the above four species described by Cavanilles are figured by him, 
I 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.
