(DCjftnttlia quadrieeta Benth., to which F. -Millar reduces China frfiformis 

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

 pines by F. -Miliar, Nov. App. (1SH;J) 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. -Millar.)
