CONTRIBUTIONS TO A FLORA OF THE OUTER HEBRIDES 167 



ed. 2, 1883, was a record of an aggregate species ; there is no 

 doubt that a second species occurs on the islands in addition 

 to T. dunense, Dum., but it is probably T. collinum, Wallr. 

 ANEMONE NEMOROSA, Linn. Mr. Ewing gives this l as vouched 

 for by Mr. A. Somerville, but I do not know where it was 

 recorded. 



RANUNCULUS TRICHOPHYLLUS, var. DEMERSUS, N. E. Brown. Dr. 

 Williams makes this the R. aquatilis, var. eradicatus, Laest. 2 

 With this I cannot agree ; I had a specimen of Laestadius' 

 plant, which is a very delicate form, not seen by me from else- 

 where. He describes it as " sub-aquaneus, caule bi-l-3-pollicari, 

 filiformi ; floribus minutissimis, ante explicationem vix semine 

 cannabis majoribus ; foliis non proprie capillaribus, sed 

 abbreviatis ; radice filiformi, fibrosa. Hab. in stagnis vadosis, 

 ex. gr. Karavuopis et Saxajerfvi ad Karesuando Lappon. 

 Tornensis." Fries included eradicatus in his Batrachium con- 

 fervoides, " Bot. Not.," 1845, p. 141, and "Sum. Veg.," 1846, 

 p. 139; and C. P. Laestadius 3 also quotes L. L. Laestadius' 

 habitats for B. confervoides, Fr. Mr. N. E. Brown seems to 

 think 4 that the eradicatus (quoted from Hiern) is something 

 different from Fries' plant. No doubt it is not the same, 

 but it is a delicate form or variety of it. 



I have a series of the Perth plant, gathered by Mr. A. 

 Sturrock. It does not seem to be mentioned in the " Flora of 

 Perth" (1898). A succulent form of Fries' plant occurs in 

 thirteen of the botanical provinces of Finland. It is B. 

 admixtum, W. Nylander. 



Hartmann 5 quotes " R. paucistamineus, Tausch, var. 

 borealis, Beurling ("Bot. Not," 1852), as a synonym of Fries' 

 plant. 



Laestadius at the end of his paper remarks " R. aquatilis 

 eradicatus, a, subaquaneus. Hujus forma minima, p. exsiccata 

 vix pollicaris ad ripas lacuum exsiccatas post defluxum aquas 

 florens caule filiformi depresso, foliis filiformibus, peltatis nullis, 

 obvenit. circa Karesuando." Specimens referable to Mr 

 Brown's plant I have from Harris, Duncan, sp. 



RANUNCULUS HEDERACEUS, Linn. Loch Boisdale in South Uist. 



TROLLIUS EUROP^US, Linn. In all floras species supposed to be 

 absent are almost as interesting as recorded ones. This is a 

 case in point. Why does Trollius grow in West Sutherland,

 until 1839.
