Limpr. — Frequent on the low ground and on the hills ; 

 above 2700 ft. it becomes commoner than the preceding, and 

 ascends to 3300 ft. At the sides of small lills, on the high 

 ground, an undulate form of FclUa is abundant, which belongs 

 to both species, but mostly to the latter, as far as I found, 

 from the specimens examined, which had inflorescence ; in 

 the barren state they cannot be distinguished with certainty. 

 P. calycina probably occurs on the low ground, but I did 

 not see any specimens which I could distinguish with 

 •certainty. 



Aneiiva palmafa (Hedw.) — -On logs in Finlarig Wood. 

 A. ambrosioides (Xees), Pears. — Common among wet rocks 

 in Finlarig Burn ravine ; frequent in marshes, ascending 

 to 2700 ft. A. pinguis (L.) — Common on wet ground to 

 3300 ft.; fr., 3000-3200 ft. 



Metzgcria pubescens (Schrank.) — Very common on Creag- 

 an-Lochan, on rock ledges ; frequent on Ben Lawers to 

 4000 ft.; not seen on the low ground. M. hamata, Lindb. 

 — Eather common in Finlarig Burn ravine, rare otherwise ; 

 Oreag-an-Lochan, 1800 ft. M. conjugata, Lindb. — Common 

 in Finlarig Burn ravine ; occasionally on the hills, noted to 

 2600 ft. M. furcata (L.) — This does not appear to be as 

 €ommon as the preceding species, but sutticient material 

 was not brought home to give its distribution with any 

 exactitude. The two last plants requii-e to be in good 

 -condition to be distinguished from each other unless 

 inflorescence be present. 



Marchantia polynKrrpha (L.) — Seen only in one locality. 

 Ben Lawers, on moist ground, beneath boulders, in the west 

 •corrie, at 3200 ft. (c. fr.). 



Conocephalus conicus (L.) — Common on the low ground, 

 rare on the hills ; Creag-an-Lochan, 1800 ft. ; above Lochan 

 Chait, 2700 ft.; Ben Lawers, 3200 ft., with the preceding. 



liehoiilia hemisphcerica (L.) — Bare ; on limestone wall by 

 roadside between Killin and Kiltyrie. 



Preissia commv.tata (Lindenb.) — Common on the low 

 ground, frequent on the hills, ascending to 3300 f t. ; fruit 

 common. The plant on the high ground has smaller and 

 narrower fronds than the low ground plant has, but I was 

 unable to find any constant difference in the fruiting 

 parts.
