DOUBTFUL SPECIES 



Leucas pubescens Benth.; Usteri Beitr. Ken. Philip. Veg. (1905) 124. 



I have seen no specimens of this species, which is definitely known only 

 from India; the identification of Usteri's specimen is probably wrong. 



Leucas marrubioides Wall.; Ceron Cat. PL Herb. Manila (1892) 135. 



The record is based on Vidal 3468 from Panay, which is perhaps a form 

 of Leucas mollissima Wall.
