APPENDIX A.—REPUTED DISCOVERIES. 123 
Triticum caninum, var. biflorum, JJitten. 
“The present is one of those Some seals by the late 
Mr. G. Don which appears to have bee erlooked by other 
botanists. His label in Mr. Borrer’s hesbaritith runs thus:— 
‘Triticum alpinum, nova spec. It differs from the caninum by 
its short arista and upright = and from the repens by 
not running at the roots.’ No date is piaronge It is thus 
clearly evident that he diGtingulanel it as a new species. The 
only British Triticum with which it can i confounded is 7. 
caninum, from which it may be distinguished by its leaves 
smooth on both sides, its usually two-flowered spikelets, and 
its want of the long awn; it also appears to be a more slender 
plant, with narrower leaves. Rocks on Ben Lawers. Mr. 
Mitten, in Hooker’s Lond. Journ. Bot., vii. (1848), Pp. 533.”

There is a specimen in Miss Palmer's collection labelled 
“Rocks, Ben Lawers (summit of).” 
It was rediscovered on Ben Lawers by Dr. Buchanan White 
and Mr. F. te Hanbury, and has been named Agropyrum 
caninum, Beauv., var. Donianum, by Dr. F. B. White, so there 
is no longer aie ambiguity” respecting it. 
The foregoing list of Don’s Reputed Discoveries may be divided 
into several groups :— 
1. The first consists of eight plants, four of which I suggested 
in the Scottish Naturalist, 1884, p. 269, were really discovered by 
Don and which might probably be refound; they were :— 
Sagina alpina. Carex ustulata. 
Juncus tenuis. Hierochloe borealis. 
In the nineteen years which have since elapsed all of these have 
been found; Sagina alpina by myself on the Cairngorms, /uncus 
tenuis scattered through Great Britain, Carex ustulata on Ben 
.Lawers in Don’s own station, and Hierochloe borealis in Kirkcud- 
brightshire. 
Besides these there aré four others which have been refound, 
viz. :— 
Salix Doniana. Caltha radicans. 
Lychnis alpina. Alchemilla argentea. 
Salix Doniana in Perthshire, Lychnis alpina and Caltha radicans
