DOUBTFUL OR EXCLUDED SPECIES 
DERRIS FERRUGINEA Benth; Ceron Cat. Pl. Herb. Manila (1892) 66. 
The Philippine record was based on Vidal 2576 from Isabela Province, 
Luzon; I suspect that the identification is erroneous. 
DERRIS DISCOLOR Benth.; Ceron Cat. Pl. Herb. Manila (1892) 66. 
The Philippine reference was based on Vidal 2665 from Basilan. The 
species is an Indian one, and I suspect the Vidal specimen to have been 
erroneously identified.
