NOTES ON THE FLORA OF PERTHSHIRE 235
Poa annua, Z., var. supina (Schrad.). On Glas Thulachan at 3000
feet, and on Ben Lawers at 3500 feet, Ben Heasgarnich, and
Ben Laoigh.
P. alpina, L. On Ben Heasgarnich. Recorded by Mr. Stewart
in Light. " Fl. Scotica" (1777), p. 96, on the side of Craig-
Challeach above Finlarig.
P. glauca, Sm., has now disappeared from the locality near Lawers,
at a low elevation, to which it was carried down by water or
wind. It is a characteristic plant of Ben Lawers, which is
curiously omitted from the list of localities given in the " Flora
of Perthshire."
P. cenisia, AIL, var. fiexuosa (WahL).
I think it will be safer to
withdraw this name, notwithstanding it was passed by Mr.
Fisher as well as by Professor Hackel. This Poa differs by its
leaf characters from both P. pratensis and P. flexuosa, but
until it has been more completely studied it will be well to
defer naming.
P. Balfouri, Parnell. Ben Lawers, Herb. Parnell, with var. rigida,
Parnell. On Ben Laoigh a form approaching P. nemoralis also
occurs. P. Balfouri is recorded from Ben Voirlich in " Ann.
N. H. S.," 1842, p. 122.
P. nemoralis, Z., var. Montana, Gaud. Ben Laoigh. and a form
approaching it on Creag-an-Lochan.
P. pratensis, Z., var. humilis (Ehrh.). On Ben Heasgarnich, Ben
Laoigh, and Ben Lawers. A very interesting variety, which
appears to be an alpine form of P. subccerulea, Smith.
Panicularia fluitans, var. subspicata (Gfyceria fltdtans}. Under the
name of Poa fluitans, var. subspicata, Parnell, from Perthshire,
is contained in Herb. Parnell.
Festuca elatior, Linn., var. intermedia, Hackel ("Monograph," p.
151). On the shingle bordering Loch Tay, at Ardtalnaig, opposite
Lawers, this variety, which is an approach to arundinacea,
occurred. It has not been previously recorded as British. It
is known from Northern Europe.
Festuca sylvatica, Vill. Under the name Poa sylvatica, var. subari-
from Perthshire in
stata, Parn., there is a form of this plant
Herb. Parnell.
Festuca rubra, Z. From 3900 feet on Ben Lawers, 3200 feet in
Isla, and 3200 feet on Ben Heasgarnich.
var. barbata (Hackel), Ben Lawers, Ben Heasgarnich, and
Glas Thulachan.
var. grandiflora (Hackel), Ben Lawers, Ben Laoigh.
