(Deyeuxia quadriseta Benth., to which F.-Villar reduces China piiformis 

 Llanos, Frag. PI. Filip. (1851) 9, non Link., has been reported from tlie Pliilip- 

 pines by F.-Villar, Nov. App. (1883) 319. As this species is known only from 

 Australia and New Zealand, it is probable that the Philippine record was based 

 on an erroneous identification on the part of F.-Villar.)
