least 1 cm long, the glumes ovate-lanceolate to lanceolate, slen- 
derly acuminate by the excurrent midrib, pale, 2 to 3 mm long. 
Utricles about 3 mm long, prominently ribbed, glabrous or nearly 
so, somewhat flask-shaped, prominently beaked. Achenes 3- 
angled, 2 mm long, rather prominently beaked, narrowed below 
and above, the beak thick, cylindric, truncate, about 0.3 mm long. 
Kwangtung Province, Loh Fau Mountain (Lofaushan), Merrill 10985, 
August 12, 1917, on dry banks in ravines, in dense bamboo thickets, altitude 
about 1,000 meters; very rare. 
I was at first disposed to refer this to Carex rhynchachaenium Clarke, 
of Luzon, which it closely resembles and to which it is closely allied. It 
differs constantly from our full series of Philippine specimens in the 
characters indicated in the diagnosis and is, I believe, specifically distinct.

Kwangtung Province, Loh Fau Mountain (Lofaushan), Merrill 10971, 
Levine 1494, August 13, 1917, in swampy places in the shade of coarse 
grasses and sedges, altitude about 1,050 meters; rare. 
Although the spikelets are at most 1.5 cm long, I believe that this form 
is referable to Sprengel’s species, which extends from India to Japan. 
Kiikenthal does not recognize this form as specifically distinct, but treats 
it as a variety of Carex japonica Thunb.

Kwangtung Province, Loh Fau Mountain (Lofaushan), Merrill 10178, 
October 28, 1916, on moss-covered boulders in shaded stream beds in ravines, 
locally very abundant, altitude about 1,100 meters. 
The specimen cited above was referred by me to the allied Carex brunnea 
Thunb., but Mr. Tutcher has called my attention to the fact that it is not 
the same as Thunberg’s. species and suggested its identity with Boott’s 
species. I have not seen the original description, but the specimen conforms 
with Kiikenthal’s description and figure, and with Khasia specimens col- 
lected by C. B. Clarke. The species occurs in India, with a variety in 
Japan, but has not previously been reported from China. The plants 
were very abundant and ' conspicuous in October, 1916, but none were in 
evidence as late as August 27 the following year; they probably develop 
very rapidly after the close of the rainy season.

The specimen is of considerable interest from the standpoint of the 
history of this species. It agrees perfectly with the descriptions and figures 
of Schott’s species. The type ( Gaudichaud ) was supposed to have been 
collected in Luzon, but although the regions that Gaudichaud visited in the 
Archipelago are now all thoroughly well known botanically, this species
