AR1STIDA Linn. 
1. A. cumingiana Trin. & Rupr. in M6m. Acad. St. Petersb. VI 7 (1849) 141. 
In the pine region at an altitude of about 1,500 m, C. M. Z. 16158- 
At low and medium altitudes in central and northern Luzon, not common; 
northern India to China. 
SPOROBOLUS R. Br. 
1. S. indicus (Linn.) R. Br. Prodr. (1810) 1810. 
Habitat not given, probably in the pine region, C. M. Z. 16206. 
Widely distributed in the Philippines at low and medium altitudes ; Tropics 
of the world. The form enumerated above is apparently the one described by 
Robert Brown as 8, elongatus. 
AGROSTIS Linn. 
1. A. elmeri Merr. in Govt. Lab. Publ. (Philip.) 29 (1905) 7. 
In open grass lands of the summit, McGregor 8832, Merrill 61/92, and in the 
mossy forest, Merrill 6483a. 
Widely distributed at high altitudes in the Benguet-Lepanto region, but un- 
known outside of this area. The species is manifestly allied to Agrostis perennans 
(Walt.) Tuclcerman, of the eastern United States, Japan, Korea, and central 
China.' For a full discussion of the latter species and its forms, see Hitchcock 
“North American Species of Agrostis” 47-50, pi. 31-33.°
