AsPLENiUM Ruta-muraria, Linn, (name confirmed by 

 Arthur Bennett). — Clefts of rocks on hillside, 480 feet 

 above sea-level, Rousay, 30th August 1916, H. H. Johnston. 

 Native. Rare. This species is, no doubt, the plant 

 erroneousl}^ recorded from Orkney as " AcROSTlCHUM 

 Septentrionale. Clefts of rocks," in " History of the 

 Orkney Islands," by Rev. Dr. Barry, ed. ii, p. 288 (1808), 

 and which latter species, under the name of " Asplenium 

 septentrionale," is included among the " Omitted Species " 

 in H. C. Watson's " Florula Orcadensis," published in 

 "Journ. Bot.," No. xiii, January 1864, pp. 11-20. My 

 record of A. Ruta-muraria, Linn., from Rousay, confirms 

 the record of this species from Orkney in " Journ. Bot.," 

 No. xiii, January 1864, p. 17. See "Scot. Nat.," No. iii, 

 new series, January 1884, p. 112; and Spence, '.'Flora
