SCIRPUS Linn. 
Scirpus pulogensis Merrill sp. nov. 
Species 8. pauciflorae Lightf. valde aftinis, differt culmis subrigidis, 
usque ad 60 em longis, dense caespitosis, spiculis lanceolatis, 8 ad 10 mm 
longis, setis perichaetii glabris. 
A perennial, densely caespitose plant, the culms terete, slender, rigid 
or subrigid, reaching a height of 60 cm, glabrous, leafless, the basal 
portions supplied with few, short, striate sheaths, tipped with linear, 
rigid, 2 to 8 mm long laminae, the sheaths of the innovations rather lax. 
Bract subtending the spikelet ovate to ovate-oblong, 4 mm long or less, 
prominently acuminate, the acumen often 1.5 mm long. Spikelets lanceo- 
late, brown or pale-brown, 8 to 10 mm long, 2 mm wide, the first two 
glumes empty, ovate, about 3 mm long, 2 mm wide, 1-nerved, brown, acute 
or slightly acuminate, the 7 or 8 succeeding glumes bearing perfect 
flowers, 4 mm long, lanceolate, acuminate or merely acute, the margins 
in the upper parts sometimes obscurely lacerate. Achene oblong, brown, 
shining, smooth, 2 mm long, 1.6 mm in diameter, trigonous, apex slightly 
acuminate, base acute; style 3.5 mm long, continuous with the ovary ; 
anthers 2 to 2.5 mm long, hypogynous bristles 4 or 6, white, slender, 
quite glabrous, equaling or slightly exceeding the achene. 
In wet depressions of the summit grass lands, altitude about 2,700 m, Merrill 
6550 (type), 6616, C. M. Z. 16134. 
This species is manifestly very closely allied to Scirpus pauciflorus Lightt., 
which is widely distributed in Europe, northern Asia south to the western Hima- 
layan region, and in North America, but appears to be distinguishable by the 
characters mentioned in the diagnosis.
