26 PHANEROGAMS AND FERNS OF SOUTH ARDGOIL. 
among short grass, and easily escaping observation on account 
of its drooping habit; in grassy places, rock ledges up to 
summits of Saddle and Tom nan Gamhna, and within a few 
feet of the true summit of Cnoc Coinnich. 
Pale Sedge (Carex pallescens, Linn.)—In sheltered places up 
to 1000 feet, and especially up the wooded allts. 
Yellow Sedge (Carex flava, Linn.)—Near to the star-headed 
carex in frequency, but in drier places up to 1600 feet. 
Tawny Sedge (Carex fulva, Good.)—One occurrence in ’ 
pasture above Lochgoilhead at 150 feet. : 
Green Ribbed Sedge (Carex binervis, Sm.)—About as com- 
mon as C. echinata and C. flava, and much commoner on the 
drier parts in grassy places, becoming tall and handsome on 
banks and in rocky hollows at considerable elevations; from 
low levels up to 1800 feet. 
Pink-leaved Sedge (Carex panicea, Linn.)—Frequent from 
300 up to 1800 feet, being especially a mid-level carex. 
Wood Sedge (Carex sylvatica, Huds.)—Occasional in wooded 
parts up to a few hundred feet. 
Bottle Sedge (Carex ampullacea, Gooden.)—The steep nature 
of the lower slopes prevents the formation of habitats to suit this 
carex, hence it is found almost wholly at mid levels from 
1000 feet upwards to 1500 feet. it is a dominant in the 
moss at 1500 feet north of the Cnoc, and elsewhere at the 
same elevation. 
Sweet Vernal-grass (Anthowanthum odoratum, Linn.) — 
Forms a constituent in almost all grass associations, from low 
levels up to 1800 feet on both Cnoc Coinnich and Ben Reithe. 
Wherever grass is well developed this one is a dominant, and 
equally so at low and mid levels; at high levels it occurs more 
sparsely. 
Timothy Grass (Phlewm pratense, Linn.) — Apparently a 
casual only. 
Floating Fox-tail Grass (Alopecurus. geniculatus, Linn.)—At 
low levels only. 
Bent Grass (Agrostis alba, Linn.), (Agrostis vulgaris, With.) 
—After Anthoxanthum odoratum this is the most common 
grass, and its two extreme forms, alba and vulgaris, are about 
equal in frequency. A. alba is the commoner grass at con- 
siderable altitudes, and A. vulgaris at low levels, where it is 
usually a dominant form in the fields. A. vulgaris is also the 
form usual in the rush associations, but both forms are found
