 District of Lepanto, Mount Data (4531 Merrill) November, 1905. On dry grassy 

 slopes in thin pine forest above 2,000 m. A second Philippine species is repre- 

 sented by No. 0592 Elmer and No. 4414 Merrill from Benguet Province. Prom

 to separate these two numbers from the Australian Galium gaudichaudii DC, 

 as determined by Mr. Elmer.
