In vol. iv., part 2 (pp. 226-230), of the Proceedings of this 

 Society, there is an interesting paper on a visit to Coll in 1879 

 by Mr. Thomas Scott, now Naturalist to the Fishery Board for 

 Scotland. In addition to giving an account of the island, several 

 plants are mentioned, most of which I also saw there during a 

 visit last summer. The species of Papaver queried in the paper 

 are Papaver- duhium, Linn., and P. Argemone, Linn. The species 

 of Utricularia are, as Mr. Scott thought they might be, Utricularia 

 minor, Linn., and U. intermedia, Hayne. Cladium is still in the 

 loch mentioned, and also grows in another loch about two miles 

 distant. Fesiuca rotthoellioides, Kunth, does not now grow on the 

 old castle where Mr. Scott found it, but I saw it in another locality. 

 The more interesting plants seen during my visit were Ranu7icidus 

 Baudotii, Godr., Draba incana, Linn., a small form growing on sand 

 dunes, as it does in West Sutherland and on the west coast of 

 Ireland ; Viola Curtisii, Forster, Anthyllis Vulner'aria, Linn., var. 

 maritima, Koch, Erythrcea Centaurium, Pers., var. cajntata, Koch, 

 Melampyrum pi'atense, Linn., var. hians, Druce, Atri'plex laciniata, 

 Linn., Orchis pyramidalis, Linn., 0. incarnata, Linn., Scilla verna, 

 Huds., Potamogeton coloratus, Hornem. { = P. ^:>/a?z^a^mez(S3 Du 

 Croz). The Kubi observed were Etcbus plicatus, W.&N., P. dumnon- 

 iensis, Bab., B. villicaidis (sp. collect.), var. Selmeri (Lindeb.), and 

 R. danicus, Focke. Specimens of these were named or verified by 

 the Eev. W. Moyle Ilogers, F.L.S. A few Hazel, Oak, and Kowan 

 trees, or rather bushes, occur, all being prostrate; also a few Aspens 

 on the faces of cliffs. The only erect indigenous trees seen were 

 two specimens of Betula 2^ubescens, Ebrh. It is an interesting 

 coincidence that this species, which has become extinct in the 

 island of Eigg within the last fifty years or so, was for many of its 

 last years limited also to two erect trees. Salix aurita, Linn.,
