NEW PLANTS FROM SORSOGON PROVINCE, LUZON 
By E. D. Merrill * 
{From the Botanical Section of the Biological Laboratory, Bureau of 
Science, Manila, P. I.) 
This paper is based almost wholly on material recently col- 
lected in Sorsogon Province, Luzon, a region in which very little 
field work has been prosecuted in botany since the exploration 
of that province by Haenke, one of the botanists of the Malas- 
pina Expedition, in about the year 1792. The field work was 
done by Maximo Ramos, who spent from July 22, 1915, to 
September 14, 1915, in Sorsogon, working on Bulusan Volcano, 
Mount Kililibong, Mount Pocdal, Mount Bogacaua, Mount Lalao, 
and at Lake Polog. In this time he collected about four hundred 
numbers of flowering plants and ferns, of which a number, on 
examination, prove to be undescribed species. In addition to 
the forty previously undescribed forms considered in this paper, 
Mr. Elmer has indicated nineteen additional sheets of this col- 
lection as representing new species, presumably in those cases 
where material collected by Ramos matches material collected by 
himself in his exploration of Sorsogon subsequent to Ramos’s 
trip. Some material, on account of inadequate specimens, im- 
mature flowers, or lack of flowers or fruits, still remains to be 
considered at a later date when the species shall have been col- 
lected again. The novelties in the collection as a whole approx- 
imate 15 per cent, which must be considered rather a high one, 
in view of the fact that field work has been actively prosecuted 
in the Philippines for about thirteen years, and that the collector, 
on whose material this paper is based, has no botanical training
