The following paper was in greater part written at Kew, in i^o\-enil3er 
and December, 1907, while Mr. ^lerrill was at the Kew Herbarium study- 
ing the types of Philippine plants preserved there, and comparing tlie 
recently collected material with the rich Philippine collections, and 
the very extensive series of Tndo-]\Ialayan and Chinese plants preserved 
at Kew. Through the kindness of Lieutenant-Colonel D. Prain, Direc- 
tor of the Eoyal Gardens, Kew, ]\Ir. E. A. Eolfe, assistant in charge 
of the Philippine collections in the Herbarium, was allowed to assist 
at this work during a part of each da}'. 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 \vere encountered during the progress of the 
work, which had apparently not been hitherto described, the descriptipns 
of man}" of these being included in tlio following paper. Various species 
previously described from other regions were found in the inaterial 
examined, and wlienever these species had not been reported from the 
Philippines, they have l)eeu included. A certain number of errors were 
met witli in tlic work of the several botanists who have published papers 
on the Philippine flora, and whenever possible, these have been corrected ;
