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 North 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. horneensis, as 

 noted by Stapf, is allied to GauUheria antipoda of Tasmania and New Zealand. 

 Other species confined to Formosa, Luzon, and Borneo are Boca swinhoii Hance, 

 Euphrasia horneensis Stapf, and Mallotus playfairii Hemsl.
