13. ERIGERON uniflorum; 
caulibus RES calyce villoso, radio erecto subtubuloso. 
E. uniflorum. Linn. Sp. Pl. 1211. Fl. Lapp. ed. 2. 250. t. 9.53. 
- Grows on Ben Lawers, and on rocks by the side of the river 
Almond, near Lindoch, seven miles from Perth. Mr. Don remarks. 
that the chfef distinction between this and the alpinum, Engl. 
Bot t. 464, is, that in uniflorum the florets of the radius are more, 
slender, and seem to be tubular, always upright, and never be- 
coming patent as in alpinum. They are also of a deeper colour, 
and the disk is constantly of a dark purple approaching to black, 
instead of a light yellow. To this we may add, that the calyx 
is always much more villose, forming, as Linneus says, a hispid 
globe before it opens. The radius seems to be often white, and 
hence he compares it to a daisy. Its erect position remains 
when dry, and a liberty appears to have been taken by the 
draughtsman of the Flora Lapponica, who certainly saw only a 
dried specimen, of making it spread almost horizontally. er 
There can in future be no difficulty in distinguishing these two 
species. Each of them is liable to bear several flowers on a stem 
when cultivated. Both grow in Switzerland as well as in Scot- 
land; but we have seen only the uniflorum from Lapland, though 
it appears by Fl. Danica, t. 292, that the alpinum is found on the 
mountains of Norway and Iceland: and indeed Linnzus in bis. 
Lapland Tour describes his plant with a yellow disk, and sketches 
the radius in a rather spreading posture; so that, though he pre- 
served the uniflorum only, he might possibly gather Both, and at 
that time confound them.
