THE HIGH ALPINE FLORA OF BRITAIN 37 



157. Lastrea dilatata, Presl. Ascends to 1052 m. on rocks on 

 the mountains of the Rannoch district ("Fl. Perthsh." 369). 



Var. alpina, T. Moore, " Ind. Filicum " (1857). Ascends to 

 1130 m. on the Grampians of Inverness-shire (Watson in herb.; 

 Hooker / " Stud. Fl. Brit. Isl.") ; and to the summit of Ben Ime 

 (J. R. Lee). 



158. Lastrea montana, T. Moore. A dwarf specimen on the 

 extreme summit of Ben Ime, near the cairn (J. R. Lee in "Ann. 

 Andersonian Nat. Soc." iii. 124 [1908]). 



159. Athyrium alpesfre, Rylands (1857). Ascends to 1065 m. 

 in damp shaded places on the mountains of Breadalbane district 

 ("Fl. Perthsh." 371); Ben Lawers (G. Don, 1794, in Herb. Brit., 

 but no height given); Corrie Sneachda, on Cairn Gorm, at 1005 

 m. (E. S. Marshall, 1898, n. 2190, in Herb. Brit); Corrie-an- 

 Lochan, on the north side of Braeriach, up to 1065 m. (E. S. Mar- 

 shall, 1898, n. 2191, in Herb. Brit.). "In July 1841 I gathered 

 two fronds of this fern in the great corrie of Ben Alder" ("Cyb. 

 Brit." iii. 253); Ben Macdhui (A. Croall, PI. of Braemar, 1854, n. 

 68 in Herb. Brit, and Herb. Kew.). Among stones and on rocks 

 in alpine districts, frequently on Highland mountains up 1220 m. in 

 Inverness-shire (Watson). Ascends to 1065 m. on the mountains 

 round Braemar (Crombie, "Braemar," p. 61). Most or probably 

 all these records refer to the var. obtusatum, Syme, " Engl. Botany," 

 ed. 3, xii. 114 (1886). This fern does not seem to develop sori so 

 freely in Perthshire as it does in Aberdeenshire (Prof. Trail). 



1 60. Athyrium flexile, Syme (1886). Ascends to noo m. in 

 damp shaded places on the mountains of the Breadalbane district 

 ("Cyb. Brit. Comp." 412). 



161. Asplenum septentrionale, G. F. Hoffm. (1795). The earliest 

 record of this fern as a British plant is by Lloyd in Gibson's edition 

 of Camden's "Britannia" (1695). He found it on the summit of 

 Carnedd Llewelyn : and it certainly grows now near Llanrwst (J. E. 

 Griffith, 1895). I n support of this, we find in Hudson, "Fl. 

 Anglica," ed. i (1762), p. 383, and ed. 2, p. 450 "ad cacumen 

 montis Carndedh Lhewelyn prope Lhan-Lhechyd in agro Arvoni- 

 ensi invenit D. Lhwyd." Smith, " English Flora," iv. 295, merely 

 repeats Lloyd's record "on the mountains of Carnarvonshire." 

 Watson, "Cyb. Brit. Comp." 414, says that the fern ascends there 

 to 3000 feet. In Scotland it is not an alpine plant. The amended 

 spelling of the generic name is adopted here as given by Ascherson 

 and Graebner, who point out that " Asplenium " is wrong and 

 meaningless and for this reason preferred by nomenclaturists. 



162. Blechnum spicant, Smith in " Mem. Acad. Roy. Sc. Turin." 

 v. 411 (1793). This reference is three years earlier than the one 

 attributed to Withering (1796) in all recent British plant-lists.
