The Bornean Species of Eugenia, Schefflera, 



and Saurauia, represented in the 



Singapore Herbarium.

Through the kindness of Mr. I. H. Burkill, Director of the 

 Botanic Garden, Singapore, I was recently loaned the Bornean 

 material of the genera Eugenia, Schefflera, and Saurauia in the 

 herharium of that institution for study. My original request for 

 this material was prompted chiefly by the idea that through a 

 study of it I would be able specifically to determine a number of 

 specimens of these three genera in the herbarium of the Bureau 

 of Science which were inadequate or incomplete. On receiving the 

 material, however, I found that although most of it comes from 

 Sarawak, from the same general regions whence I have received most 

 of my own Bornean material, comparatively few of the specimens 

 match unidentified material in the herbarium of the Bureau of 

 Science, and a number of sheets represent species entirely different 

 from any of the named species in the latter herbarium. This fact 

 impresses me with the belief that as yet the extant Bornean botani- 

 cal material represents a relatively small part of the species that 

 actually occur in Borneo, and that intensive field work in botany 

 will add several thousand species to the list of those already record- 

 ed from this relatively little known Island. The results of my 

 study of the Singapore material of the three genera under discussion 

 are given below. 



Eugenia, Linnaeus. 



An examination of the Bornean material representing this 

 genus in the Singapore herbarium has induced me to propose and 

 describe six new species, and to enumerate the specimens represent- 

 ing other species so far as I have been able to identify them. In 

 addition to the twenty-seven species listed below at least eleven 

 others are represented, but in most cases the material is scarcely 

 sufficient to determine whether or not the}* represent described 

 forms, and if described to which species they appertain. There 

 are now about eighty-five species of the genus credited to Borneo ; 

 but the list will certainly be greatly extended. There are, in addi- 

 tion to the eleven Bornean species in the Singapore herbarium
