On Some Coll and Tiree Plants.

[Read 29th December, 1896. ] 
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 dubium, 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. Festuca rottbellioides, 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 Ranunculus 
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 Vulneraria, Linn., var. 
maritima, Koch, Lrythrea Centauriwm, Pers., var. capitata, Koch, 
Melampyrum pratense, Linn., var. hians, Druce, Atriplex laciniata, 
Linn., Orchis pyramidalis, Linn., 0. incarnata, Linn., Scilla verna, 
Huds., Potamogeton coloratus, Hornem. (=P. plantagineus, Du 
Croz). The Rubi observed were Rubus plicatus, W.&N.,R. dumnon- 
iensis, Bab., R. villicaulis (sp. collect.), var. Selmert (Lindeb.), and 
. danicus, Focke. Specimens of these were named or verified by 
the Rey. W. Moyle Rogers, F.L.S. A few Hazel, Oak, and Rowan 
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 pubescens, 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,
