near the pan., spikelets few 1 2-flowered. y. glauca; st. 

 slender, pan. with many long-stalked spikelets, plant glaucous. 

 d. P. montana (Parn.) ; spikelets few of 2 or 3 free fl., knots 

 4 or 5 uppermost rather above the middle of the stem. P. .39. 

 Shady places, y. and 8. Mountains. P. VI. VII. 



8. P. Parnellii (Bab.) ; pan. erect large rather close oblong, 

 spikelets ovate of 2 or 3 acute free fl., lower pale with 5 veins 

 but only 3 hairy, upper sheath usually longer than its leaf, upper 

 knot at about the middle of the st. exposed, ligule very short 

 truncate. E. B. S. 2916. P. 93. St. ascending, 1 ft. or more 

 high, compressed ; knots 5 or 6, uppermost not above the middle 

 of the stem. Ligule 6 times as broad as long, but longer than 

 that of P. nemoralis, to which this is perhaps too nearly allied. 

 Occasionally there is a slight trace of a web to the florets. Higli

9. P. Balfourii (Parn.) ; pan. erect rather spreading, spikelets 

 ovate of 3 or 4 webbed fl., lower pale with 5 veins but only 3

 the stem without knots, ligule prominent obtuse. P. 66. E. B. 

 S. 2918. Root creeping. St. 315 in. high; knots about 3, 

 uppermost within the lower third of the stem. Lower fl. as long 

 as the larger glume. I cannot join this to P. nemoralis without 

 more proof of their identity than has vet appeared. Tops of
