than its leaf. Glumellas distinctly nerved, not spotted. 
Stem rough towards the top.—b. rubescens Rent. (Lake

15. L.-sheaths shorter than the internodes, the upper one 
shorter than its 1., the nodes, in consequence, not

2—1 fls. The form exposed to the sun (b. firmula Gaud.) 
stiffer, the spikelets containing 3—5 fls; the mountain

rarely (d. glauca Gaud.) the Is glaucous.—Woods, walls, 
rocks; everywhere. 6 nemoralis L. 2479.
