Culm smooth and round, furnished with 2 or 3 Jeaves, 
about 4 or 5 inches high, Leaves flat, subulate, and 
‘somewhat hairy, 1 to 2 inches in length, and about 2 
lines wide; sheathes shorter than the internodes, very 
Hairy around the stipules. Spikes 2 or 3, somewhat oval, 
subtended by a single leaf, with which they are at first 
sheathed; rachis compressed, margined, spikelets 6 to 8, _ 
by pairs, inclined to one side. Calix 2-valved, 2 or 3-flow- . 
ered, valves very unequal, each with a single nerve and — 
carinate, the larger oblong-ovate, mucronulate. Outer _ 
_ valve of the corolla oblong-lanceolate, entire, 3-nerved, 
smooth, and membranaceous, longer than the calix; inner 
2-nerved, nearly the length of the outer. Anthers linear, 
entire, fulvous, exserted. Styles filiform, pubescent. 
This species appears on the one hand, allied to..4the- 
ropogon, and on the other to Dactylis. Though rather a 
Sesleria than any other genus, it recedes from it in hav- — 
ing the valves of the corolla entire at the apex, and thus — 
it approaches Dactylis, at least, the D. glomerata. a 
With the exception of the: present species, the genus 
Sesleria is’ confined to the alpine regions of Northern’ 
Europe. es,
