thick, with a few very prominent shghtly rough cartilaginous ribs, 
bright green, not glaucous; ligule short, blunt. Panicle oblong- 
cylindrical, subtruncate at the base, abruptly rounded at the apex, 
broadest near the base ; panicle -branches with 2 to 6 spikelets. 
Spikelets oval-oblong. Glumes united at the base for about one-fourth 
of their length, subconnivent at the tips, gradually acuminate and 
acute, as long as the pales, submembranous, densely or thinly silky- 
pubescent, greenish-white, with a dark green or dark purple narrow 
stripe on each side of the keel, and another parallel to the inner 
margin extending nearly to the base ; keel not winged, ciliated (as are 
also the ribs) with very long silky hairs throughout. Awn absent, or 
from a little below the middle of the pale, and extending beyond the 
glumes for about half their length, and often much less. Anthers

Yar. 3, Watsoni. 
Panicle rather lax, usually longer than that of var. a. Glumes 
connivent at the tips, more gradually acute than those of var. a, with 
lead-coloured or purple lines, and frequently also tinged with purple. 
Awn extending beyond the glumes for one-third or one-fourth of 
their length. 
In wet places on mountains. Local. IS^ot unfrequent in the glens 
of the Clova Mountains, reaching up to Canlochan Glen, Forfar. 
Abundant on Loch-na-gar, and sparingly above Loch Kander, at the 
head of Glen Callater; in which coimty it is said to occur also on 
Ben-mac-dhui, and Braeriach. I possess a specimen with the label 
" Ben Lawers, W. H. Campbell," but I never could find the plant 
on that mountain, though I searched for it carefully. In the Cybele 
Britannica," Ross and Moray are given as counties in which it occurs, 
but I have not seen specimens from either. Yar. 3, Canlochan Glen 
(Mr. H. C. Watson) ; above Loch Kander, head of Glen Callater, and 
on Loch-na-gar, growing with var. a. 
Scotland. PereJinial. Summer, Autumn. 
Yar. a has the stems 6 to 18 inches high. Leaves of the barren 
shoots 4 to 9 inclies long, those of the tiowering stem considerably
