NOTES ON PHILIPPINE BOTANY. 



By ElMER D. INlERRiLL and R. A. Rolfe. 



{From the Botanical Section of the Biological Laboratory, Bureau of Science, 



Manila, P. I., and from the Kew Herharium, London, England.) 



The following paper was in greater part written at Ivew, in November 

 and December, 1907, while Mr. Merrill was at the Kew Herbarium study- 

 ing the types of Philippine plants preserved there, and comparing the 

 recently collected material with the rich Philippine collections, and 

 the very extensive series of Indo-Malayan and Chinese plants preserved 

 at Kew. Through the kindness of Lieutenant-Colonel D. Prain, Direc- 

 tor of the Poyal Gardens, Kew, Mr. E. A. Eolfe, assistant in charge 

 of the Philippine collections in the Herl)arium, was allowed to assist 

 at tliis work during a part of each day. The Kew Herbarium con- 

 tains more than 25,000 specimens of Philippine plants alone, includ- 

 ing the duplicate material forwarded by the Bureau of Science, which is 

 by far the largest collection of Philippine plants extant, with the excep- 

 tion of that of the Bureau of Science. 



A number of species were encountered during the progress of the 

 work, which had apparently not been hitberto described, the descriptions 

 of many of tliese being included in the following paper. A^arious species 

 ])revious]y descril)ed from other regions were found in the material 

 examined, and whenever these species had not been reported from the 

 Pliilippines, they have been inchided. A certain mimber of errors were 

 met with in the work of the several botanists who have published papers 

 on the Pliilippine flora, and whenever possible, these have been corrected;
