THE FLORA OF MOUNT IIALCON.

evidence is not confined to the higher altitudes of Mindoro, for the char- 
acteristic Malayan or Indo-Malayan genera represented by Clirysophyllum 
roxburghii and Ocliiocharis javanica, both species of low elevations, are at 
present known in the Philippines only from this island. However, as 
other Bornean and Australian types are known in the Philippines only 
in Luzon, the botanical evidence alone is not conclusive. 
In the present paper and in those by Copeland , Brotherus and Ames 
on the Halcon flora, considerably over 600 species are considered, for 
the greater part collected on two short expeditions, both made under 
very unfavorable conditions for collecting and preserving botanical ma- 
terial because of the prevailing rains, Mr. Merritt’s expedition having 
been made in June, and my own in November. Considering that in 
this region plants flower throughout the year, different species at different 
seasons, it seems very probable that we at present know considerably less 
than one-half the species actually growing on Halcon, and that future 
exploration will yield much material and many data of value. Halcon 
then, like Kinabalu, must still be considered to be very imperfectly known 
botanically, the former rather better than the latter, for in Stapf’s paper 
on the flora of the latter only about 450 species are enumerated.

Borneo. 
This species was previously collected on Halcon (Dulangan) by Whitehead, 
and reported by Rendle: The above specimens exactly match fragments of No. 
1697 Beccari, from Mount Mattang, Sarawak, Borneo, kindly supplied me by 
Dr. Beccari, except that the leaves of the Halcon specimens are slightly smaller 
than in the Borneo plant. An interesting Bornean type in the Philippine flora.
