3_4 acute florets, outer glumellas silky at the keel and marginal 
nerves glabrous between them, upper sheath longer than its 
leaf, upper ligule long and acute, leaves all flat narrow linear 
acuminate. P. flexuosa Sm. : E. B. t. 1123. — «. panicle some- 
what erect, florets connected by a web, outer glumella with two 
intermediate glabrous nerves. P. minor Gaud. — /?. panicle 
lax slightly drooping, florets without a web, outer glumella 
without intermediate nerves. P. laxa Pam. Gr. t. 38 (and 
most others). 
Ben Nevis, Loch-na-gar, and Clova mountains. I/.. 7, 8. — 
Very slender, scarcely able to support the weight of its own panicle , 
slightly glaucous. Leaves more numerous than in P. alpina, and 
much narrower. Florets very obscurely ribbed, all very acute, green 
and purple, with diaphanous margins, sometimes connected by a web, 
sometimes free, often viviparous. Glumes nearly equal. Both vari- 
eties have been found in each of the above localities. 
15. P. nemoralis L. ( Wood M.) ; tufted or slightly creep- 
ing, panicle slender, spikelets ovate or lanceolate of 2 — 5 
florets, florets silky at the keel and marginal nerves, uppermost 
sheath usually as short as its leaf, ligule obtuse or truncate. — 
a. upper sheath as short as the leaf, ligule extremely short 
truncate, florets slightly webbed. E. B. t. 1265: Pam. Gr. t. 
36. — [3. uppermost sheath usually longer than its leaf, ligule 
extremely short truncate, florets free. P. glauca Sm. (partly). 
P. Parnellii Bab.: E. B. S. t. 2916: Pam. Gr. t. 93. — y. 
uppermost sheath as short as the leaf, its joint about the middle 
of the culm, ligule prominent obtuse, spikelets greenish, florets 
free. P. montana Pam. Gr. t. 39. — 8. uppermost sheath as 
short as its leaf, its joint near the base of the culm, ligule pro- 
minent obtuse, spikelets purplish, florets free. P. glauca Sm. 
in E. B. t. 1720? — f. uppermost sheath as short as its leaf, 
ligule prominent obtuse, florets webbed. P. Balfourii Pam.

Common in woods and thickets. — 0. Upper Teesdale. — y. Ben 
Lawers. — S. and e. Mountain-tops in Upper Teesdale, Wales, and 
Scotland. If.. 6, 7. — A very variable species, to which we have no 
hesitation in referring all the above as varieties : and, indeed, although 
we have arranged them as such, in order that our readers may see 
the differential characters assigned to them, we remain of the opinion 
stated in former editions, that there is no valid reason for distinguish- 
ing any of the mountain forms. As to P. ccesia of Smith, referred by 
Smith himself to his P. glauca, there is some doubt, the figure in 
E. B. t. 1719 being rather ambiguous ; Mr. Borrer informs us that 
he has never seen it except in gardens, and perhaps it is merely the 
fertile form of P. alpina , the root, which, according to Smith, is 
tufted, agreeing with that species ; what is usually so called is re- 
ferable chiefly to our var. 5., and sometimes to e. ; Mr. Mackay’s speci-
