34 ANNALS OF SCOTTISH NATURAL HISTORY 



6 1. Rub-its chamcBmorus, L. Ascends to 1067 m. on the 

 mountains of the Rannoch district, in peaty places (" Fl. Perthsh." 

 124). "Upon the mountains about Loch Rannoch" (Lightfoot, 

 "Fl. Scotica," 266). Ascends to the summit of Glas Maol, on the 

 Aberdeenshire side (J. Barton, 1859, in Herb. Brit, ex herb. 

 Trimen); and to 1160 m. on Ben-na-Bourd (F. B. White in "Scot. 

 Nat." i. 119 [1871]). 



Fam. 21. ONOTHERACE^. 



62. Epilobium alpinum, L. Ascends to 1 190 m. on Ben Lawers, 

 by alpine springs, rills, and damp places (F. B. White). " Found 

 near the snow upon Ben More in Breadalbane, July 2, 1771; 

 more than 2500 feet above the sea" (Wm. MacRitchie, in Herb. 

 Brit.). " Tops of the hills between the head of Clova and Invercauld 

 in Aberdeenshire" (R. Brown, 1794, in Herb. Brit.). 



63. Epilobium alsinifolium, Vill. Ascends to 1037 m. on the 

 mountains of the Breadalbane district, as on Ben Lawers, "in 

 little rills at very great heights east side of Ben Lawers " (R. Brown, 

 1794, in Herb. Brit.); in or near alpine and subalpine rills and 

 streams, or among damp rocks, but not very common. "This 

 species seems not to descend along the rivers, like some other 

 mountain plants, to any great extent" ("Fl. Perthsh." 156). On 

 the margins of alpine rivulets high up on Ben Nevis (Alexander 

 Murray, about 1820). Descends to 305 m. on the limestone cliffs 

 of Glenade, in Leitrim, growing in the springs and at the foot of 

 small trickling waterfalls, just sufficient to keep the rocks thoroughly 

 wet (Barrington and Powell, in "Journ. Bot." 1884, 247); the 

 only locality known for this plant in Ireland. 



Fam. 22. SAXIFRAGACE^;. 



64. Saxifraga autumnalis, L. Common in the Highland area. 

 Ascends to 1175 m. on Ben Lawers in marshy places, chiefly alpine 

 and subalpine. Sides of rills on Ben Lawers (Wm. Gardiner, 1842, 

 in Herb. Brit.). This name does not seem to have been taken 

 up in English floras. Whether S. aiitumnalis, L., is conspecific with 

 S. aizoides, L., I cannot say, but S. autumnalis is the earlier name 

 of the two (for those who insist on actual priority) ; and all the 

 Scottish alpine examples under the name of S. aizoides which I have 

 examined agree with the Linnean description of S. autumnalis, and 

 not with that of S. aizoides the differential characters of the form 

 and margin of the leaves are very obvious. I may also point out 

 that specimens named aizoides in the Linnean Herbarium also 

 obviously belong to S. autumnalis. This, however, counts for little, 

 as Linnaeus was notoriously indifferent to the critical naming of 

 specimens in his herbarium, and based his species mainly on
