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 pap is based almost wholly on material recently col- 

 lected in Sox ogon Province, Luzon, a region in which very little 

 field work has been prosecuted in botany since the exploration 

 of that pro\ uce 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
