The commonest representative of this well-marked section in the Philippines 

 seems to be E. vulpina Reichb. f. This and E. jusca Bl. were the only Tricho- 

 tosias credibly reported from the Islands before the American occupation. Recent 

 collections have added four species before unknown, two of them herein described 

 for the first time. In proposing fresh additions to the section, it must be con- 

 fessed that t he elimination of such older species as have never been pictured, or 

 of which some representation other than verbal has not been available, has often 

 been difficult. The descriptions of the earlier botanists are now inadequate; more- 

 over, even the very detailed diagnoses of present writers have sometimes proved 

 ambiguous, owing no doubt to the comparative characterlessness of the species 

 of this section. It is imperative that authors of new species of § Trichotosia 

 publish figures exhibiting distinctive characters.
