PREMNA l.iiiii. 



In F.-Villar's ISTovissima Appendix to tlie third edition of Blanco's 

 Flora, de Filipinas, 11 species of Preinna are enumerated. Of these 

 eleven species, but two are here enumerated under the same names as those 

 used by F.-Villar, Fremna adenosUda Schauer and F. cumingiana 

 Schauer. From synonomy and other sources I have been able satis- 

 factorily to reduce five species, /'. foetida F.-A"ill., non Eeinw. ; F. pithcs- 

 cens F.-Vill., non Blume; F. reditu Schauer; F. tomentosa F.-Vill., non 

 Willd., and F. mucronata F.-Yill., non Eoxb., while judging from the 

 native names cited the species enumerated as Fremna vihurnoides Wall., is 

 F. nauseosa Blanco. Fremna pliilippiiiciisis Turcz, is a species of Vite.r. 

 y. turczanlnowii ^Merr.-^ Freinna gaudichaudii Schauer is enumerated 

 l)y F.-Villar, but is not credited to the Philippines, this with F. marian- 

 naram, the remaining species of Villar's list, shoidd l)c excluded from 

 the Philippine flora, unless at some future time nuiterial is collected tliat 

 agrees with the descriptions of these species.
