+ var. dentata Koch. The typical glabrous form, and f. 



hirta, among rocks by the west side of Tingwall Loch, Scalloway. 



Suseda maritima Dum. var. procumbens Syme. U. 



Abundant by the north shore of Balta Voe. 



J Atriplex patula L. U. A maritime form by Balta Voe. 

 Var. erecta. S. Corn-field near Scalloway. 



A. Babingtonii Woods. U. Shores of Balta Voe. Yell, 

 shore at Gutcher. S. Scalloway. 



% var. virescens Lange. (t. Lange) With the last in the 

 two first-named localities, and apparently the more common form. 

 Both are, doubtless, general along the coast line. It seems pro- 

 bable that the var. virescens is the " A glabriuscula " Ed- 

 mondston. Watson includes A. hastata, and Edmondston states 

 that A. deltoidea Bab. is abundant"; but I did not meet with 

 either, although my gatherings were somewhat numerous. 



Rumex obtusifolius Auct. U. At Baliasta, on waste ground. 

 S. Somewhat frequent about roadsides at Scalloway. Not 

 common, and always looking starved, and as though unsuited to 

 the climate ; thus in strong contrast to the three following species. 

 The plant from Scalloway I had thought might be var. silvestris 

 (Wallr.), and Dr. Lange writes " probably ; " but the plant was 

 not sufficiently mature to allow of certainty. 



R. crispus L. Generally distributed, and rather common. 



R. domesticus Hartm. This is the commonest Dock of the 

 islands, and grows in luxuriance in all suitable spots, both by the 

 sea and inland. (R. aquaticus Edm.) 



t R. conspersus Hartm. U. About Baltasound and Bali- 

 asta. S. Scalloway, about the coast, as well as inland in many 

 places. So far as I have seen, as generally distributed as the last, 

 and perhaps not much less common. This is probably R. acutus 

 Edm. (at least in part). I did not see R. acutus L. (pratensis), 

 but it may occur, as it is recorded from Orkney by Dr. Boswell. 

 Some, botanists have thought that R. conspersus is a hybrid be- 

 tween domesticus and obtusifolius ; Dr. Lange considers it to be a 

 hybrid of R. domesticus and acutus. 



A curious form occurs at (U.) Baliasta growing with R. obtusi- 

 folius. This plant, Dr. Lange thinks, may be i: R. conspersus 

 *platypkyllus Aresch. (?) " which " seems to be a hybrid between 

 domesticus and aquaticus" The perianth is much like that of 

 conspersus ; but the leaves are very different, resembling closely
