soft hairs. Leaves flaccid, plane, narrowly lanceolate, 8 to 11 
cm long, 5 to 8 mm wide, acuminate, conspicuously ciliate on 
both surfaces with scattered, soft, spreading, 2 to 3 mm long 
hairs usually from papillate bases; sheaths with hairs similar 
to those on the leaves, longer than the internodes, the upper 
ones somewhat inflated; ligules less than 0.5 mm long, densely 
and minutely ciliate. Panicles up to 13 cm in length, when 
young more or less inclosed in the uppermost sheath, the branches 
strict, ascending, the lower ones up to 6 cm in length. Spikelets 
narrowly lanceolate, about 6 mm long, usually one sessile and 
one pedicelled at each node, the rachis and branchlets angular, 
scabrid. Empty glumes two, narrowly lanceolate, acuminate, 6 
mm long and about 1 mm wide, 3-nerved, very slenderly acumi- 
nate, sparingly ciliate with long, soft hairs. Flowering glume 
hyaline, lanceolate, 5 mm long, very faintly 1-nerved, slightly 
cleft at the apex, the awn slender, straight when wet, sometimes 
slightly bent when dry, up to 1 cm in length. 
Kwangtung Province, Loh Fau Mountain (Lofaushan), Merrill 10701, 
August 25, 1917, on thin earth over boulders along streams, altitude 900 
to 1,000 meters. 
This species is somewhat allied to Garnotia stricta Brongn. but is readily 
distinguished by its prominently ciliate leaves, sheaths, and more sparingly 
ciliate empty glumes, the hairs being very slender, white or pale, spreading, 
2 to 3 mm in length, and usually from papillate bases. It occurs only 
in a very special habitat, on thin soil associated with mosses covering large 
boulders and ledges which are not subject to overflow in times of flood. 
It must be a short-lived plant, as on August 25, 1917, it was conspicuous 
on boulders at our camp site, the plants a few days previous to this date 
presenting no inflorescences; in October, 1916, the old dried remains of 
the same species was observed in the same locality, but no specimens were 
then prepared as the spikelets had all fallen and the plants were all withered 
and dry.

AGROSTIS ELMERI Merr. in Govt. Lab. Publ. (Philip.) 29 (1905) 7. 
Kwangtung Province, Loh Fau Mountain (Lofaushan), Merrill 1092U, 
August 16, 1917, in the wet sandy bottoms of drained pools, altitude about 
1,000 meters; a few plants observed in a single restricted area. 
The genus is new to Kwangtung Province, and I can see no reason for 
considering the specimen cited above as representing other than a rather 
slender form of Agrostis elmeri Merr., a species previously known only from 
the higher mountains of the Philippines. The spikelets are distinctly 
jointed below the empty glumes, but Mr. Hitchcock, of the United States 
Department of Agriculture, calls my attention to, the fact that this character 
is not uncommon in Agrostis, occurring even in the common Agrostis alba 
Linn. The spikelets of this form are but about one-half as large as are 
those of Agrostis hugoniana Rendle, to which Agrostis elmeri Merr. is 
apparently allied.
