(From the Botanical Section of the Biological Laboratory, 
Bureau of Science, Manila, P. I.) 
The second paper under the above title was published in 1914,’ 
and the present one is in all respects similar to it, being based 
primarily on botanical material collected by Mr. C. A. Wenzel, 
in Leyte. In the first two papers seventy-one new species were 
proposed, while in the present one twenty-one new species are 
described and the new genus Wenzelia of the family Rutaceae. 
The genera Trigonopleura and Sarcostigma are new to the Philip- 
pine flora. New forms are described in the following families: 
Rutaceae, Euphorbiaceae, Moraceae, Commelinaceae, Urticaceae, 
Fagaceae, Burseraceae, Araceae, Symplocaceae, Myristicaceae, 
Flacourtiaceae, Caprifoliaceae, Lauraceae, Melastomataceae, and 
Icacinaceae. A few notes on nomenclature are included.
