1 68 ANNALS OF SCOTTISH NATURAL HISTORY 



The only form I have as yet seen from the Outer Hebrides. 

 Dr. Shoolbred records A. vulgaris, L., from North and South 

 Harris, but I have not seen specimens. 



A. ALPINA, Z. On Ceartaval at 1800 feet, Duncan, sp. "High- 

 lands at 450 feet," Watson, " Comp. Cyb. Brit." p. 166, 1870 ; 

 "300 feet in Westerness," Macvicar, "Trans. Bot. Soc. 

 Edin." p. 179, 1899. Not recorded for Orkney a curious 

 absentee. 



A. ARVENSIS, L. Fields in Scarp, W. S. Duncan. 



SAXIFRAGA OPPOSITIFOLIA, L. Harris mountains in the east, middle, 

 and west. North gully just behind stream, Ulladale, at 600 

 feet. On Husival More (1603 feet), but a short way above 

 the base with Oxyria reniformis. 700 feet in Westerness, 

 Macvicar. 



This saxifrage remains 151 days in flower in Norway. 1 



S. STELLARIS, L. At 400 feet in Glen Ulladale, W. S. Duncan. 

 700 feet in Westerness, Macvicar. 450 feet in Wales, Watson, 

 "Comp. Cyb. Brit." p. 180, 1870. Less than 600 feet in W. 

 York, Lees, " Fl. W. York." p. 788, 1888. 



CHRYSOSPLENIUM OPPOSITIFOLIUM, L. W. Tarbert, Harris, W. S. 

 Duncan, sp. Not recorded from Shetland. 



CAUCALIS ANTHRISCUS, Hitds. Harris, W. S. Duncan. In E. 

 Sutherland, but not in W. Sutherland, Orkney, or Shetland. 



VALERIANA OFFICINALIS, L. - - North and South Harris, W. S. 

 Duncan. 



CARDUUS HETEROPHYLLUS, L. Obbe, Duncan, sp. This is the 

 ordinary form of the species, with undivided finely dentate 

 leaves. The form with the leaves much cut into segments 2 

 seems rare in Britain. There is a sp. in the " Brit. Mus. Herb." 

 (Forster's herb) from the Isle of Mull ; and I have it from 

 Inverness (W. A. Nicholson, sp.\ and a very extreme form (or 

 a hybrid with lanceolatus?) from Forfar (E. S. Marshall, sp.}. 

 In this the anthodes (5) are agglomerated at the apex of the 

 stem, which is leafy up to the lowest anthode, and the leaves 

 are all cut into narrow segments to within two lines of the 

 midrib. Dr. Williams ("Prod. Fl. Brit." 2, p. 50, 1901) says 

 "ascends to 500 metres," but it certainly grows up to 2500 feet 

 in Perthshire. 3 



ACHILLEA MILLEFOLIUM, L. Some of the Hebridean specimens of 

 this seem as much referable to the var. lanata, Koch, as to 

 alpestris. Koch refers the A. Seidleri, Presl., to alpestris

2 Var. laciniosum, Norrl. (sub. Cirsium), "Herb. Mus. Fenn.'' 103, 1889.
