which it strongly resembles in habit. The latter species was found in abundance 
in the open grass lands above the limits of the mossy forest, and on’ the return 
trip, a few specimens of the plant above described were gathered, chiefly on 
account of the habitat, it being so entirely different from the usual habitat of 
Agrostis elmeri. In making the preliminary identifications of the Mount Pulog 
material, this number was referred to Agrostis elmeri, but in working over the 
material more carefully the number was found to consist of both the Agrostis, 
and the genus above described. 
CALAMAGROSTIS Roth. 
1. C. filifolia Merr. in Philip. Journ. Sei. 1 (1906) Suppl. 179, 375. 
i The most common grass on the open slopes above the mossy forest, C. M. Z. 
e 16180, Merrill 6610, 6611, McGregor 8891, also in the upper pine region at the ; 
lower limits of the mossy forest, 0. M. Z. s. n. : ' 
} Known only from the higher mountains of the Benguet-Lepanto region, and 
most closely allied to species of South America and New Zealand. 
DESCHAMPSIA Beauv. 
1..D. flexuosa (Linn.) Trin. in Bull, Acad, Sci. St. Pétersb. 1 (1836) 66. 
Aira flecuosa Linn. Sp. Pl. (1753) 65. : 
In open grass lands of the summit, rather common, C, M. Z. 16155, Merrill 
6354, McGregor 8904. 
A striking addition to the northern element in the Philippine flora, no species 
of the genus being previously known from the Archipelago. Deschampsia flexuosa 
is widely distributed in northern Asia and Europe, and in North America, from 
Greenland south along the mountains to.North Carolina and Tennessee, also in 
Japan, and on Mount Morrison, Formosa; it is not reported from the Himalayan 
~ region, nor from China, although Deschampsia caespitosa (Linn.) Beauv. is 
found in both regions. The identification of the above species has been kindly 
verified by Doctor Hackel. 
ELEUSINE Gaertn. 
1. E. indica (Linn,) Gaertn. Fruct. 1 (1788) 8. 
In stream depressions, lower pine region, 0. M. Z. 16211. 
Abundant and widely distributed in the Philippines at low and medium alti- 
tudes; Tropics of the Old World, now widely distributed in temperate and tropical 
regions in America. 
ERAGROSTIS Host. 
1, E. distans Hack. in Govt. Lab. Publ. (Philip.) 35 (1905) 81. 
Steep slopes in the pine region, C. M. Z. 16160. 
Known only from medium altitudes in the Benguet-Lepanto region.
