JJ nder " Ceratophyllum, demersum" for "Loch of Ay re, 

 Kirbister," read Loch of Ayre, Hohn. See ' The Scottish 

 NaturaHst," No. 1, New Series, July 1883, p. 22, where 

 Mr. W. Irvine Fortescue has recorded the late Mr. Robert 

 Heddle's two stations for this species as " Loch of Ayre, 

 Hubbin at Kirbuster." The foinner station is in the parish 

 of Holm, and the latter one in the parish of Orphir, both 

 in Mainland and seven miles apart. 



With reference to " Zannichellia jpaliistris, Linn. — 

 Kirbister Loch, 1850, Syme," this species is recorded from 

 that station by Mr. John T. Syme (afterwards Dr. J. T. I. B. 

 Boswell) in " Trans. Bot. Soc. Edin.," vol. iv, part i, p. 48 

 (1850); but, on 31st December 1878; the late Dr. Boswell 

 informed me that the above-mentioned name was an error, 

 and that the correct name of the plant he found in the 

 Loch of Kirbister is Z. polycarpa, Nolte, var. b. tenuissirna, 

 Fries. Z. palustris, Linn., has never been seen in Orkney 

 by Dr. Boswell, and " 111 Orkney, Syme sp.," under this 

 species, should, therefore, be omitted from H. C. Watson's 

 " Topographical Botany," ed. ii, p. 424 (1883). The " Syme 

 sp." probably refers to the specimens collected by Mr. Syme 

 in 1849, and at that time erroneously labelled by him 

 as "Zannichellia palustria, Linn.," as already explained 

 above. 



Luzula pilosa, Willd, has never been seen in Orkney by 

 Dr. Boswell, Dr. Foi-tescue, Mr. Magnus Spence, nor by me, 

 although I have specially looked for it during the present 

 year in Mainland and Hoy, where L. sylvatica, Gaud., is 

 common in many different localities. Mr. Patrick Neill, 

 in his " Tour through Orkney and Shetland," in 1804, 

 p. 186 (1806), records this species under the name of 

 " Juncus pilosus, Hairy Rush," from Rousay. 



Under " Festuca bromoides, Linn.," for " Skail " read 

 Skaill. 



Equisetum palustre, Linn., var. midum, Newm., was 

 recorded from Orgill, Hoy, by the late Rev. E. S. Marshall, 

 in " Journ. Bot.," vol. xxxix, August 1901, p. 275. 



Under " Ophioglossum vulgatum, Linn., var. amhiguum, 

 Coss. et. Germ.," for " Miss P. Deuche " read Miss P. 

 Deuchar.
