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

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

 — S. P. montana (Paru.); spikelets few of 2 or '6 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 (Bah.) ; pan. erect large rather close oblong, 

 spikelets ovate of 2 or 3 acute free fl., lower pale with 6 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.— i;. 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. — High 

 Force and other parts of Upper Teesdale. P. VII. E. 



9. P. Balfourii (Paxn.) ; pan. erect rather S])reading, spikelets 

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

 hairy, upper sheath about as long as its leaf, upper two-thirds of 

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

 S. 2918. — Root creeping. St. 3 — 15 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 yet appeared. — Tops of 

 mountains. P. VII. E. S. 



ttt Lower pan.-branches suhverticillate. Dorsal vein of 

 the lower pale hairy ; marginal glabrous. 



10. P. trivialis (L.) ; pan. diffuse, spikelets ovate of 2 or 3 

 acute webbed fl., lower pale with 5 veins, upper sheath much 

 longer than its leaf, ligule acute long. — E. B. 1072. P. 36. — 

 Root tufted. St. 1^2 ft. high. Sheaths shghtly rough. — /3. par- 

 viflora (Parn.) ; spikelets small I — 2-flowered, plant slender. — 

 Moist and shady places. P. VI. 



*** Boot creeping by long stoles. 



11. P.pratmsis (Ij.); pan. difi^use, spikelets ovate of 3 or 4 

 wehbed fl., lower pale with 5 prominent veins but only 3 hairy, 

 upper sheath much longer than its leaf, ligule prominent obtuse. 

 — iJ. B. 1073. P. 31 — 34. — Very variable in size. St. com- 

 pressed and sheaths nearly always smooth. Fl. strongly webbed= 

 — /3. subcterulea ; spikelets broader, 1. broad and short, upper 1.
