230 THANSACTKmS AND I'KOCEEDINGS OF THE [Sess. Lxvi. 



Mr. Pearson, in his "Ilepaticse of the British Isles," mentions 

 as being, in his opinion, different from A. variant, but 1 

 think that the fine specimens from Ben Lawers show it to 

 be the same plant. A. corallioides (Nees) — Bather common 

 on boulders in the western corrie of Ben Lawers, from 

 2800—3200 ft. Fruit seen only in one place. Uncommon 

 on the east side of the hill. A. concinnata (Lightf.) — 

 Common on the higher parts of Ben Lawers, from 2800— 

 4000 ft., generally on earthy or gravelly soil : on earthy 

 soil, at 1300 ft. Frequently in fruit. Occurs also on the 

 other hills, but is not as common as the following : — 

 A. obtusa (Lindb). — Common on boulders and rocks on Ben 

 Lawers, frequent on the other hills ; fruit frequent. 



Saccogyna viticulosa (Mich.) — Bather common in Finlarig 

 Burn ravine. 



Fossomhronia Dumortieri, Lindb. — On the sandy shore of 

 Loch Tay, at Ardmore, in some quantity, in hollows in 

 which there is decayed vegetable matter. This locality 

 was shown to me by Mr. W. Young, from whom I had 

 previously received specimens with spores. Mr. P. Ewing 

 also sent me specimens, gathered by him in 1883, which 

 he informs me were distributed under another name. It 

 is an interesting addition to the flora of Scotland. This 

 is the commonest species of the genus in Scandinavia, and 

 should be looked for in other parts of Scotland on damp 

 sandy heaths. 



Pallavicinia Bli/ttii (Moerck.) — Ben Lawers, in several 

 places, on small peaty banks on grassy slopes, from 3100— 

 3400 ft. The bracts of the female flowers, which were 

 present in all my gatherings, at once distinguished this 

 species from Pcllia. The frond is also more lobed than in 

 Pellia, and the colour different ; when fresh, it bears a good 

 deal of resemblance in colour to Salix herbacca, which occurs 

 on the same kind of ground ; fruit not seen. 



Blasia pusilla, L. — Common in wet gravelly places on 

 the low ground, Finlarig- Burn, etc. ; only seen on the hills 

 at Creag-an-Lochan, 1900 ft., on moist gravelly soil, and 

 Meiller Bog, at about 1800 ft. 



Pcllia epiiihylla (L.) — Common on the low ground, and on 

 the hills to about 2700 ft., ascends to 3000 ft.; but not 

 identified with certainty above this. P. Neesiana (Gottsche),
