NEW OR NOTEWORTHY PHILIPPINE PLANTS, XVI 



By Elmer D. Merrill 

 Director and Botanist, Bureau of Science, Manila 



The sixteenth paper of this series is essentially like its prede- 

 cessors, the last number having been published in 1919.^ The 

 present paper contains the descriptions of about one hundred 

 presumably hitherto undescribed species of flowering plants, 

 with some notes on nomenclature and some proposed changes 

 in generic and specific names, as well as the records for a few 

 species previously described from extra-Philippine material now 

 found for the first time in the Archipelago. The genera Fihrau- 

 rea of the Menispermaceae, Phyllochlamys of the Moraceae, Eil- 

 rycoma of the Simarubaceae, and Ixonanthes of the Linaceae are 

 new to the Philippine flora, the last two being represented by 

 previously undescribed species. 



A large number of the new species described in the present 

 paper is from the eastern coast of Surigao Province, Mindanao, 

 and the neighboring islands of Dinagat, Siargao, and Bucas 

 Grande, regions in which no intensive botanical collecting has 

 hitherto been done. Extensive collections were made in these 

 regions by Messrs. M. Ramos and J. Pascasio, April to June, 

 1919; and, as is usual in previously unexplored regions in the 

 Philippines, their material contains a high percentage of pre- 

 viously undescribed species. Doubtless any general collection 

 made in the same regions, but at a different time of the year, 

 would yield an equally high percentage of novelties,
