MiNDORO, Mount Halcon, Merrill 5725, 
Widely distributed in the highlands of north-central Luzon, at altitudes of 
from 1,500 to 2,250 m, also at high altitudes on other mountains in southern 
Luzon and in Mindoro. It has been collected several times in Formosa.

This species was originally described and figured from material collected on 
Mount Kinabalu, British Nortli Borneo, and soon afterwards was collected in 
northern Luzon by Whitehead and reported from the Philippines by Rendle. I 
have examined the type of the species in Herb. Kew, and can see no valid reason 
for distinguishing the Philippine form even as a variety. Judging from the 
description and figure, the Formosan species G. itoana, recently described by 
Hayata, is quite the same as the Bornean and Luzon form. G. horncensis, as 
noted by Stapf, is allied to Gauliheria antipoda of Tasmania and New Zealand. 
Other species confined to Formosa, Luzon, and Borneo are Boea sicinhoii Hance, 
Euphrasia horneensis Stapf, and Mallotus playfairii Hemsl.

An endemic species like the preceding, widely distributed in the Philippines at 
higher altitudes. The species described by me as D. scandens, is certainly only 
a form of D. luzonica, with somewhat thinner leaves and rather more hairy 
branches and leaves than the type.
