The fact that types are stored in a part of the building far 

 removed from the general herbarium has materially added to 

 the difficulties in making current identifications, and much 

 time is lost in going from the general collection to the type 

 collection. This, however, cannot be safely remedied until 

 proper fireproof quarters are supplied for the entire collection. 



Publications. — A list of papers which have been published 

 in Section C, Botany, of the Philippine Journal of Science is 

 given elsewhere. A paper entitled "Philippine dipterocarp 

 forests," by W. H. Brown and D. M. Mathews, prepared during 

 the year, was published in, and fills the last two numbers of, 

 Section A, Chemical and Geological Sciences and the Industries, 

 of the Philippine Journal of Science. This paper is a very 

 extensive and most important physiological and ecological study 

 on the distribution, composition, effect of cutting and clearing, 

 and management of the chief dipterocarp forests of the Phil- 

 ippines. Mr. Merrill has prepared an extensive paper entitled 

 "A contribution to the bibliography of the botany of Borneo," 

 containing over 500 titles, which has been submitted to Mr. J. 

 C. Moulton, Sarawak, for publication in the Sarawak Museum 

 Journal. Other papers by Mr. Merrill and Doctor Brown are 

 in press, and still others are ready for the printer and in 

 preparation. 



Uncompleted work. — There are three especially extensive 

 collections of extra-Philippine botanical material from Borneo, 

 from China, and from Amboina, which have not been worked 

 up, although considerable work has been done on the Borneo 

 collection. Our most important project on extra-Philippine ma- 

 terial is the one from Amboina, which was interrupted by the 

 sad death of Doctor Robinson. His collections are now at the 

 Bureau of Science. The collection as it stands is one of the most 

 important that has been made in the Malay Archipelago- — 

 important, not so much from the fact that new species are to be 

 expected, but because the bulk of the species represented will 

 be of great value in interpreting the species of the older authors 

 that by reference are based on the figures in Rumphius's 

 Herbarium Ambolnense and not on actual specimens. The ma- 

 terial has been arranged in two series : First, those specimens 

 that could be definitely referred to plants described or figured 

 by Rumphius in his Herbarium Amboinense ; and secondly, those 

 that are apparently not described by Rumphius. The first series 

 has been distributed into sets under the title 'Tlantae Rum- 

 phianae Amboinenses," the Rumphian name and reference being 

 added to each label. It is planned, before distributing the ma-
