NEW PLANTS FROM SAMAR 
By E. D. Merrill' 
{From the Botanical Section of the Biological Laboratory, Bureau of Science, 
Manila, P. I.) 
The present paper is devoted to the description of new species 
of plants from Samar, chiefly from the collections made by M. 
Ramos and G. Edano, of the Bureau of Science, in northern 
Samar in February and March, 1916. Thirty-two new species 
are proposed and described in the families Araceae, Urticaceae, 
Opiliaceae, Aristolochiaceae, Amaranthaceae, Annonacecie, Myr- 
isticaceae, Lauraceae, Burseraceae, Meliaceae, Euphorbiaceae. 
Anacardiaceae, Sapindaceae, Vitaceae, Tiliaceae, Sterculiaceae, 
Theaceae, Guttifercie, Flacourtiacecie, Myrtaceae, Loganiaceae, 
Verbenaceae, and Acanthaceae. 
Perhaps the most interesting single addition to the Philippine 
flora is the genus Petersia of the Lecythidciceae, for which the 
new generic designation Peter sianthns is proposed below. The 
genus was previously known only from tropical Africa, where it 
is represented by two species. The discovery of a third species 
of this caracteristic genus in the Philippines is of special in- 
terest. It was originally described as a species of Terminalia, 
the material on which it was based presenting only leaves and 
old fruits. The recently collected Samar material presents two 
specimens with flowers, so that it has been possible from a study 
of these to determine its proper position.
