as the larger glume. — Summits of mountains. Perth and Forfar 
shires. P. VII. S. 
6. P. compressa (L.) ;• panicle slightly unilateral spreading 
(when in fl. otherwise close), spikelets ovate or oblong-ovate, fl. 
5 — 7 obtuse slightly webbed at the base, upper palea with 3 hairy 
nerves, upper sheath about as long as its leaf, ligule short obtuse. 
— E. B. 365. Par. 3/. — Root creeping. St. decumbent at the 
base, then erect, very much compressed, 1 — ljfoot high. Upper- 
most joint at about the middle of the stem. — Dry situations. P. VII. 
** Flowers not webbed. 
7. P. pohjnoda (Par.) ; panicle erect ovate-lanceolate, spikelets 
ovate or ovate-lanceolate, fl. 4 — 5 obtuse not webbed, outer palea 
with 5 nerves dorsal and marginal ones hairy, upper sheath not 
longer than its leaf, ztppermost joint above the middle of the st., 
ligule short obtuse. — Par. 39. — Root creeping. St. decumbent 
at the base afterwards erect, compressed, 1 — 1^ foot high. Joints 
7 or 8, second at about the middle of the stem. L. acute. Pa- 
nicle with short branches. Lowest fl. not longer than the larger 
glume. — Dry stony soil. Edinburgh. P. VI. VII. S. 
8. P. Parnellii; panicle erect large rather close oblong, spike- 
lets ovate, fl. 2 or 3 acute not webbed, outer palea with 5 nerves 
dorsal and marginal hairy, upper sheath longer than its leaf, upper 
joint at about the middle of the stem exposed, ligule very short obtuse. 
— St. ascending, 1 foot or more high, compressed. Joints 5 or 6, 
the uppermost not above the middle. Very different in appear- 
ance although closely allied in characters to the preceding, but in 
my opinion truly distinct. I name it in compliment to Dr. R. 
Parnell, the author of a valuable work on Scottish Grasses, who 
first pointed out to me its claims to distinction. — High-force in 
Teesdale. P. VII. E. 
9. P. caisia (Sm.) ; panicle erect slender, spikelets ovate of 3 
or 4 acute fl., outer palea with 5 nerves the dorsal and marginal 
hairy, vpper sheath not longer than its leaf, uppermost joint near 
to the base of the st. concealed, ligule short obtuse. — Par. 40. — 
Root fibrous. St. 6 — 12 in. high. The lower fl. longer than the 
large glume. The want of any web and the acute fl. are the only 
distinctions between this and P. Balfourii. I consider it quite 
distinct from P. nemoralis. — Mountains. P. VII. E. S. 
10. P. montana (Par.) ; panicle erect close slender, spikelets 
few lanceolate-ovate of 2 or 3 fl., outer palea with 5 nerves the 
dorsal and marginal hairy, upper sheath not longer than its leaf, 
7ippermost joint at about the middle of the stem, ligule prominent 
obtuse. — Par. 40. — Root creeping. St. 12 — 18 in. high. Joints 
4 or 5, highest rather below r than above the middle. In my 
rather imperfect specimen the upper joint is exposed. Panicle
