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, op- 

 posite 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- 

 stata, Parn., there is a form of this plant from Perthshire in 

 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.
