THE HIGH ALPINE FLORA OF BRITAIN 233 



128. Carex pilulifera, L. On alpine pastures ascends to 1005 

 m. in the Scottish Highlands ("Cyb. Brit. Comp." 377), but not 

 so high in Perthshire (see "Fl. Perthsh." 333). 



Var. longebracteata, Lange " Handb. Dansk. Fl." 694 (1864). 

 Found up to 1067 m. on Ben Avon (E. S. Marshall and W. A. 

 Shoolbred, 1905, in "Journ. Bot." 1906, 160). This plant is not 

 identical with var. Leesti, Ridley, according to Mr. Druce, though 

 Lange himself said he could see no difference between the two. 

 Lees's specimen in Herb. Brit, does not seem readily separable 

 from the Danish plant. 



129. Carex binervis, Smith. First recorded by James Beattie 

 as " very common on the driest moors about Aberdeen." Ascends 

 to 1000 m. on the Grampians of Aberdeenshire (Hooker, f.). The 

 blackish-fruited form frequent in mountain localities (the species 

 varies greatly) should most probably be referred to var. alpina, 

 Drejer, "Rev. Crit. Car." 474 (1841). Descends to sea-level in 

 Cork. 



[In ed. 9 of Babington's " Manual," p. 455, C. rHpestris, Bellardi, 

 is stated to occur on lofty mountains. As far as I know, however, 

 the highest level reached by the plant is only 793 m., on Ben 

 Heasgarnich (White). C. rariflora, Smith, is stated to have been 

 discovered by Don " among the mountains of Clova, Angus, near 

 the limits of perpetual snow." As no point on the Clova hills is as 

 high as 1000 m., and much less reaches "the limits of perpetual 

 snow," an entirely unknown phenomenon on any part of the 

 Grampian Mountains, more recent and confirmatory evidence is 

 necessary before accepting this record.]

130. Nardus stricta, L. Ascends to 1005 m. on dry pasture 

 in Aberdeenshire (Watson). Descends to sea-level in Kerry. 



131. Festuca ovina, L. Summit of Ben Macdhui (Watson, 

 1832), and of Ben-na-Bourd (Watson, 1844). "On the ledges of 

 the highest rock of Snowdon " (Banks, 1773, m Herb. Brit). Near 

 the top of Ben Lawers (G. C. Druce in "Ann. Scot. Nat. Hist." 

 1900, 235). Summit of Ben Inie (J. R. Lee in "Ann. Andersonian 

 Nat. Soc." iii. 121 [1908]). Summit of Cam Tual ("Cyb. Hib." 

 ed. 2, 429). Descends to sea-level in Cork. 



Var. duriuscula (L.), Hackel. Ascends to the summit of Been- 

 keragh (Hart, iSSi, in " Proc. Roy. Irish Acad." 1882, p. 578). 



132. Festuca rubra, var. arenaria (Retz), Fries, " Fl. Halland." 

 28 (1817). Ascends to 1065 m. on the mountains of the Breadal- 

 bane district (MacVicar in "Ann. Scot. Nat. Hist." 1905, 173). 



Var. grandiflora, f. alpina, Hackel. Ben More (E. S. Marshall).
