tinguish from that plant. JV. compressa (Hook.) — Submerged 

 in a small loch, Creag Mhor, Glenlochy ; P. Ewing, July 1898. 

 A form with the leaves markedly squarrose. N. scalaris 

 (Schrad.) — Common everywhere to 4000 ft. N. silvrctice 

 (Gottsche) — A small alpine form on Creag-na-Caillich, 

 2500 ft. 



Mai'Siqjella emarginata (Ehrh.) — Common on the hills ; 

 ascending to 3200 ft. M. Funcldi (Web. & Mohr.) — On 

 a disused road, Kiltyrie ; on gravelly soil, Bein Ghlas, 

 1000 ft.; Ben Lawers, 1300 ft. This species has been 

 reported as occurring on the hills, but I failed to find it 

 there. Fruit is fairly common on the west coast, but I did 

 not see it in Perthshire. M. usUdata, Spruce. — Creag-an- 

 Lochan, 2000 ft., on rocks; Ben Lawers, in a few places, 

 from 2700-3900 ft., on gravelly soil; fruit common. 

 \M. condensata (Angstr.), Kaalaas own Lindb. — In abundance 

 on bare moist humus on the east side of Ben Lawers, at 

 3200 ft. Determined by Herr Kaalaas. This interesting 

 addition to our flora forms a brown carpet on parts of the 

 hill where little else grows, except Conosfomum boreate. 

 The shallow lunate sinus, without a hyaline border to the 

 leaf, is characteristic, but the specimens were so luxuriant 

 that I thought it could not be this species. Herr Kaalaas, 

 however, mentions that he has seen similar large specimens 

 from a few places in Norway. It is a high alpine species, 

 confined to Xorth Europe and the Austrian Alps. It is 

 considered by Herr Kaalaas to be the same plant as 31. 

 cemula (Limpr.), with which opinion Prof. V. Schiffner 

 agrees. A full account of the species, with excellent 

 figures, will be found in Kaalaas's " Beitriige zur Leber- 

 moosflora Norwegens," 1898. 



Acolea crassifolia (Carr.) — Ben Lawers, 3900 ft. In 

 quantity, on gravelly soil, near a snow patch (c. fr.). This 

 species has been previously found in the district by 

 C. J. Wild and G. Davies. A. varians (Lindb.) (Sarcoscyphus 

 confcrtus, Limpr.). — Frequent in many parts of Ben Lawers, 

 from 2800 ft. to at least 3400 ft., forming large patches 

 on gravelly soil, and fruiting freely. This plant bears a 

 close resemblance to A. crassifolia, and I find much difficulty 

 in distinguishing them in the field. It has previously only 

 been gathered on Ben Xevis as a few scattered stems, which
