THE FLORA OF ISIOI'NT IIALCON. 257 



evidence is not confined to the higher altitudes of Mindoro, for the cliar- 

 acteristic Malayan or Indo-Malayan genera represented hy Chnjsophyllum 

 roxhurghii and Ochtocharis 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 i)aper and in those 1)y Copeland, Brotherus and Ames 

 on the Halcou flora, considerably over GOO 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. MerriU'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 viold much material and many data of value. Halcon 

 then, like Kinabalu, must still l)e considered to be very imperfectly known 

 botanically, the former rather l^etter than the latter, for in Stapfs ])aper 

 on the flora of tlic latter only al)Out 450 species are enumerated.

AGATHIS Salisb. 



Agathis philippinensis Warb. ^ronsnnia 1 (1900) 18.5, t. S. f. E.

DACRYDIUM .Soland. 



Dacrydium falciforme (Pari.) Pilger in Enol. Pllanzenreich 18 (in03) 4.'). 

 PodorariJiis falcifonnis Pari, in DC. Prodr. 16' (1808) ()85. 



In forests at 1,800 m. alt. (No. r,744) ; also collected by Mcrrilt in June, 1000. 

 at 160 m. alt. (No. 4425). 



Borneo. 



This species was previously collected on Halcon (Dulangan) by Whilchcnd. 

 and reported by Rendle.' The above specimens exactly match fragments of No. 

 1(>1)7 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 J^orneo plant. An interesting Bornean type in the Philippine flora.
