of nomina conservanda as adopted by these two congresses. 

 Such changes in nomenclature as have been proposed in the 

 following list are in accordance with the rules of the Inter- 

 national Code. While certain necessary new combinations have 

 been made, and certain new names have been proposed, this 

 bibliographic enumeration has not been made a vehicle for the 

 publication of new species, but includes only those that have 

 elsewhere been described. 



While the genera are arranged according to the sequence in 

 de Dalla Torre and Harms's Genera Siphonogamarum, the 

 species under each genus have been arranged alphabetically 

 under their accepted names. No attempt has been made to 

 compile a complete list of synonyms, even of those names based 

 on Indo-Malayan specimens and references, but all synonyms 

 that I have detected that are based on Bornean specimens have 

 been included. Otherwise only sufficient synonymy has usually 

 been added to explain the accepted name. In general the 

 original place of publication has been indicated for each species. 



Considerable attention has been given to form and 

 uniformity in bibliographic citation, but it has not always been 

 possible for me to cite volume numbers and dates of publication 

 for certain periodicals, as in numerous cases these are not 

 indicated in the literature available to me, and can only be' 

 determined by actual examination of the original publications. 

 In such periodicals as the Gardener's Chronicle and Curtis's 

 Botanical Magazine there is great lack of uniformity in their 

 citation, in botanical literature, and the older volumes of these 

 two series are not available in Manila. 



In the preparation of this list, as I have not had an 

 opportunity to examine more than a very small percentage of 

 the specimens on which the actual Bornean records were 

 originally based, I have, of necessity, been obliged to accept the 

 reported identifications as correct in most cases. It is very 

 certain, however, that were it possible to assemble most of the 

 extant Bornean botanical material in one place, and make a 

 direct comparison of the actual types, a certain number of 

 reductions would have to be made; again a critical comparison 

 of Bornean types with material from the Malay Peninsula, 

 Sumatra, Java, the Philippines, and other islands in the Malayan 

 region will probably show that an appreciable percentage of 

 Bornean species that are now indicated as endemic, are really 

 the same as those occuring in other regions. It will doubtless 

 be found to be true that where species have been credited to 

 Borneo in general works without the citation of specimens, that 

 the identifications of the Bornean specimen as representing a 

 certain extra-Bornean species will on re-examination prove to 

 be approximate rather than exact.
