slightly creeping. St. slender, 1—2 feet high. Sheaths smooth. 
—B. angustifola ; st. and panicle very slender, 1. long and nar- 
row, uppermost knot near the panicle, spikelets few 1—2-flow- 
ered.—y. glauca; st. slender, panicle with many long-stalked 
spikelets, plant glaucous.—d. P. montana (Parn.); spikelets few 
of 2 or 3 free fi., knots 4 or 5, uppermost rather above the middle 
ee P. 39.—Shady places. y. and 6. Mountains. P. 
8. P. Parneilii (Bab.) ; panicle erect large rather close oblong, 
spikelets ovate of 2 or 3 acute free /fl., outer pale with 5 nerves 
the dorsal and marginal 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, | 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.

9. P. Balfourii (Parn.) ; panicle erect rather spreading, spike- 
lets ovate of 3 or 4 webbed fl., outer pale with 5 nerves the dorsal 
and marginal 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 ap- 
peared.—Tops of mountains. P. VII. E. 8. 
+tt Lower branches of the panicle subverticillate. Dorsal 
nerve of the outer pale hairy; marginal glabrous. 
10. P. trivialis (L.); panicle diffuse, spikelets ovate of 2 or 3 
acute webbed fl., outer pale with 5 nerves, upper sheath much 
longer than its leaf, ligule acute long. —E. B.1072.  P.35.—

webbed fi., outer pale with 5 prominent nerves the dorsal and 
marginal hairy, upper sheath much longer than its leaf, ligule 
prominent obtuse.—E. B. 1073. P. 31—34.—Very variable in
