B. roseum.. 
W. cruda, the alpine glaucous Thread Moss; W. albicans and 
B. pseudotriqguetrium, fruit in June and July on mountainous banks 
and rocks. W. carnea, the pink-fruited Thread Moss, fruits in 
May on moist clay banks ; while W nutans, the silky pendulous 
Thread Moss, and #&. /acustre, the small round fruited Thread 
Moss, frequent moist sandy places. &. neodamense is found on 
Southport sands, where it is liable to inundation ; it is also reported 
as occurring in the East Highlands. 
A very rare fruiting species although frequent on sub-alpine 
moist rocks is B. alpinum, the alpine purple Thread Moss. ‘This 
is one of our most elegant species, and is usually known by the 
brilliant coloured foliage. ‘The capsule becomes deep red as it 
ripens. 
B. Muhlenbeckii is a doubtful species, and &. Stirtonz or barbalum, 
found by Dr. Stirton, is only recorded from Ben Ledi. 4. Sautert 
is another very rare and doubtful species. 
The drooping Thread Moss, &. Zendulum, is not infrequent on 
walls and rocks; and &. zzclinatum, the small-mouthed Thread 
Moss, on walls, banks, and decayed trees: both fruiting in May. 
Fruiting in June are B. sorguescens, the twisting Thread Moss ; 
B. obconium, the obconical Thread Moss ; 2. Dontanum, Don’s 
Thread Moss; B. provincale; B. murate; B. erythrocarpon ; B. 
atropurpureum and B. Funkit. 
Conspicuous for their large size and broad leaves, being amongst 
the largest of the acrocarpous Mosses, is the genus A/nzum, grow- 
ing on the ground or on rocks in shady situations. They are 
distinguished from the Bryums by the mode of innovation of the 
stems, which is from the lower part; by the filiform paraphyses of 
the barren flower ; by the texture of the leaves; and in general by 
the larger size of the species. 
The leaves vary much in shape and disposition, often roundish— 
elliptical, spathulate, ligulate or more or less lanceolate, and are 
either serrated or entire, and with or without a cartilaginous border. 
A. Leaves sharply serrated a margin cartilaginous.
