mon in Finlarig Burn ravine, otherwise rare ; very rare on 

 the hills, but occurs in a few places on Creag-an-Lochan, 

 1700-1900 ft. 



Jungermania cordifolia, Hook. — Common in springs and 

 sides of streams on Ben Lawers, from 2500-3300 ft. ; 

 frequent on Cam Chreag and Creag-an-Lochan ; fruit 

 common, and usually in abundance when present ; Finlarig 

 Burn, at 700 ft. and at 1200 ft. /. j^umila, With. — 

 Very common on wet rocks at the side of Finlarig Burn 

 in the ravine ; Kiltyrie ; Creag-an-Lochan, on wet rocks, at 

 1800 ft. J. atrovirens, Schleich. in JJvm. Syll.\ confirmed 

 by Herrn Kaalaas and Stephani. — In quantity on wet 

 rocks, Creag-an-Lochan, 1800-2000 ft.; Ben Lawers, 

 3200 ft.; Cam Chreag, 2700 ft.; Creag-na-Caillich, 

 2600 ft. I cannot satisfy myself as to the position of 

 this plant. In its dioicous inflorescence and flagelliform 

 stems it agrees with J. ri'paria, but it difi'ers much from 

 that species, as I have seen it from rocks on the low 

 ground, where it is of a dirty green colour, and with 

 perianths which are pyriform and deeply plicate. J. riixiria, 

 however, occurs also in stoney marshy ground on the hills, 

 and in these positions it is occasionally dark green in colour, 

 and the perianth sometimes oblong-ovate. J. atrovirens 

 agrees with J. jnimila in its colour, shape of leaf, and to a 

 large extent in its perianths, for although the perianth 

 of J. pumila is typically fusiform and hardly plicate, it is 

 not unfrequently oblong-ovate and plicate to the middle. 

 Flagellffi are also sometimes present on the stem, but not 

 as a rule, and are very few when they do occur. The 

 difference in the inflorescence is important, J. inimila 

 being paroicous. The perianths of these plants being 

 examined when they are at the same stage of growth, 

 when it is mature, but before the egress of the capsule, 

 it will be found that even under those conditions there is 

 a considerable variation to be seen. On the whole, I am 

 inclined to regard J. atrovirens as an alpine variety of 

 J. riparia. J. riparia, Tayl. — Eather common in wet 

 places, both on the low ground and on the hills, ascending 

 to 3200 ft. J. splicer ocarpa, Hook. — Bare; near the 

 exposed summit of Creag-na-Caillich, at 2900 ft., as typical 

 J. lurida, Dum.; on more sheltered ground, at 2700 ft..
