An examination of the botanical literature covering the 

 Malay Peninsula, Java, and the Philippines reveals the fact that 

 several hundred species are definitely known to occur in these 

 three regions, which have not as yet been reported from Borneo, 

 and do not occur in the Bornean collections available to me for 

 study. It is highly probable that all or most of these will 

 eventually be found in Borneo, as they are largely the 

 characteristic weeds and weed-like plants as well as cultivated 

 and semi-cultivated species that have for the most part been 

 disseminated purposely or inadvertently by m.an; doubtless 

 many of them are represented in Bornean collections already 

 made, but not having been definitely credited to Borneo in 

 botanical literature they are not included in the present list. I 

 do not consider the statement as to geographic distribution 

 " India to Malaya " or " Malaya " sufficiently definite to warrani 

 including a species as Bornean in the absence of other data, 

 although unquestionably most species thus indicated probably 

 occur in Borneo. 



As already noted by me*, no references to Borneo have 

 been found in pre-Linnean botanical literature except a few 

 in Rumphius's Herbarium Amboinense (1741-1755) but written 

 between the years 1655-1701, and none have been detected in 

 the post-Linnean literature before the year 1839, except a 

 single doubtful reference to Borneo in Volume five of de 

 Candolle's Prodromus (1836) sub Pluchea indica Less. The 

 reason for the lack of references to Borneo in early botanical 

 literature is that no collections were made in Borneo prior to 

 Korthals's pioneer work in about the year 1836. Since that time, 

 however, very extensive botanical collections have been made 

 in various parts of Borneo, but apparently no single large 

 collection has been thoroughly worked up. Among the numerous 

 collectors may be mentioned Korthals, Beccari, Low, Motley, 

 Barber, Lobb, Burbidge, Teysmann, Ridley, Creagh, Fraser, 

 Haviland, Hose, Grabowski, Brooks, Shelford, Hewitt, Moulton, 

 Hallier, Nieuwenhuis, Jaheri, Amdjah, Schlechter, Winkler^ 

 Brooks, Foxworthy, Mrs. Clemens, Miss Gibbs, Topping, Yates, 

 VillaniiK and Agama. To Dr. O. Beccari's pioneer work in 

 Sarawak, more than to any other single individual, we are 

 indebted for our present knowledge of the Bornean flora, 

 his collections probably exceedin&__iii extent and value those 

 of any other single collector yt^ has worked in- Borneo. 



As indicated above extensive botanipal collections, notably 

 those of Haviland, Hallier, Jaheri, certain groups in Beccari's 

 large collection, and others have been only partly worked up, 

 so that the present enumeration of Bornean plants is decidedly 

 incomplete in reference to collections already made. The
