 Mainland, 27th September 1921 (plants in unripe fruit),

[Valeriana pyrenaica, Linn. — Plantation of trees, 80 

 feet above sea-level, Binscarth, Firth, Mainland, 2nd June 

 1921, H. H. Johnston. Not native. Plants introduced 

 into Orkney and planted at Binscarth prior to 18S0, since 

 which time the plants have multiplied and spread in the 

 plantation, where they are now common. Plants in flower. 

 —Corolla lilac. This species is recorded from Orkney in 

 "Annals Scot. Nat. Hist.," No. 27, p. 173 (July 1898); and 

 in Spence, "Flora Orcadensis," p. 33 (1914); but having 

 been planted in an artificial plantation of trees, and being 

 still confined to that plantation, it has no claim to be 

 included in the flora of Orkney, any more than the exotic 

 trees in the same plantation.] 



The aggregate species Taraxacum officinale, Wigg., is 

 recorded from Orkney in Watson, "Top. Bot.," ed. ii, p. 236 

 (1883), but the following segregate species are not mentioned

 aged). Corolla yellow, striped dull purplish beneath. 

 Anthers purplish-yellow. Style and its two branches 

 pale brownish-yellow. Plants in fruit on 6tli June 1921.
