PREMNA Linn. 



Iii F.-Villar's Novissima Appendix to the third edition of Blanco's 

 Flora de Filipinas, 11 species of Premna are ('numerated. Of these 

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

 used by F.-Yillar. Premna adenosticta Schauer and /'. cumingiana 

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

 factorily to reduce live species, /'. foetida F.-Vill.. noti Reinw. ; P. pubes- 

 cens F.-Vill., non Blume; /'. vestita Schauer; P. tomentosa F.-Vill., non 

 Willd.j and P. mucronata F.-Vill., non Roxb., while judging from the 

 native names cited the species enumerated as Premna viburnoides Wall., is 

 P. nauseosa Blanco. Premna philippinensis Turcz, is a species of Vitcx, 

 V. turczaninowii Merr. 24 Premna gaudichaudii Schauer is enumerated 

 by F.-Villar, but is not credited to the Philippines, this with P. marian- 

 narwn, the remaining species of Villar's list, should be excluded from 

 the Philippine flora, unless at some future time material is collected that 

 agrees with the descriptions of these species.
