some material from Dr. Hubert Winkler from Dutch Borneo, 
miscellaneous Bornean material from the Botanic Garden at 
Buitenzorg, Java, and from the collections of Mr. H. N. Ridley, 
formerly director of the Botanic Garden at Singapore. Recently 
there has been received a small but interesting lot of botanical 
material, chiefly representing the commercial timber trees 
of British North Borneo, collected by Mr. A. Villamil in the 
service of the Forestry Department of British North Borneo, 
and finally very extensive collections from Mount Kinabalu, 
British North Borneo, made by Chaplain and Mrs. Clemens and 
Mr. D. Le Roy Topping, October to December, 1915. This Kina- 
balu collection is probably by far the largest that has ever been 
taken from that mountain by any single expedition, but the 
material, only recently received, has not been available in the 
preparation of this paper. 
It has been known for some years that there is a remarkable 
phytogeographic relationship between the Philippines and the is- 
lands to the south and southeast. Without taking into consider- 
ation cases of special and limited specific distribution, it .is only 
necessary to enumerate some of the striking genera that are 
known only from the indicated regions. Some of these are 
Sararanga, Microlaena, Ascarina, Phrygilanthus, Spiraeopsis, 
Clianthus, Wallaceodendron, Reinwardtiodendron, Strophiobla- 
chia, Koordersiodendron, Oncocarpus, Pleiogynium, Cubilia, Tris- 
tira, Ganophyllum, Euphorianthus, Pimelea, Schuurmansia, 
Eucalyptus, Osbornia, Xanthostemon, Gyrinopsis, Anompanax, 
Lepiniopsis, and Dolicholobium. On the other hand, only four 
genera are known from Borneo and the Philippines and confined 
to them, and two of these hardly extend into the Philippines 
proper. These are Philbornea, Borneo-Palawan ; Eusideroxylon, 
Borneo-Sulu Archipelago; Clemensia; and Hallieracantha. The 
list of species known only from Borneo and the Philippines is 
equally poor when compared with the list known from the Philip- 
pines and Celebes, or the Philippines and the Moluccas as a 
group. In the year 1909 but about thirty species of the limited 
distribution Philippines-Borneo were known 2 and but a single 
genus, Hallieracantha. Some of the species have since been 
found in other regions, so that this list has now been somewhat 
reduced. Additions, however, increase the total, such as Dino- 
chloa ciliata Kurz, Albizzia scandens Merr., Dalbergia subaltrni- 
2 Merrill, E. D. The Malayan, Australian, and Polynesian elements in 
the Philippine Flora. Ann. Jard. Bot. Buitenz. Suppl 3 (1909) 287.
