NOTES ON MOSSES. 133 
Capsule oblong-ovate, black-brown, pale at base. Male inflore- 
scence gemmiform. Fruiting June and July. Three varieties of 
this species are found. f /régéda, plants more robust ; y amata, 
leaves rather lax and glossy ; 6 falcata, more slender, back ; leaves 
falcato-secund from a broadly ovate base. 
Closely resembling the last species is A. crassinervis. It is 
readily recognised by the subulate point or excurrent nerve, which 
is bordered with a single row of cells having the appearance of 
papillze when seen by reflected light. Fruits July and August. 
While in all the previous species the leaves and _pericheetial 
bracts, that is the bracts surrounding the base of the fruit-stalk, 
show considerable difference in shape, &c., in A. nzvalis, the tall 
slender Andrea, they are alike in form. The capsule is also deeply 
cleft into 4, 6, or 8 valves. 
It is a dioicous Moss in soft, blackish green, widely spreading 
tufts. Stems 3-4in. high, slender, reddish, branches forked. 
Leaves patent, secund, the lower, smaller ovato-lanceolate ; the 
upper, falcato-secund, acute, densely papillose on both sides ; 
nerve narrowed, and lost in the apex; capsule a little exserted, 
oblong ; calyptra very small, conical. ‘This fine species, fruiting 
in July and August, appears to attain its fullest development on 
the Grampian range, its habitat being the higher mountains of 
Scotland, on dripping rocks, at the limit of perpetual snow. 
Found with the typical form on Ben Nevis and Ben Macdhui 
is a variety B fuscescens, with stems more flexouse and flabby, 
and strongly falcate leaves of a brown colour. 
A rather minute plant is the small-mouthed beardless Moss, 
Gymnostomum microstomum with stems 4-jin. high, and fruiting 
in spring on banks and in fields. 
Weissta crispula, the curly leaved Weissia, is found fruiting in 
June and July on mountainous rocks, where also is found 
Lhabdoweissia denticulata, the toothed streak Moss. 
A very small and pretty series of plants, greatly resembling each 
other and requiring care to distinguish, is the genus Seligeria, 
Bristle Mosses, named in honour of the Silesian pastor Seliger. 
Found growing on rocks ; the leaves are in many rows, lanceolate 
. or subulate, nerved, cells minute and quadrate above, large and 
rectangular at base, sometimes with coloured angular cells, see 
Dicranum, calyptra cucullate, capsule ovate or globose with a 
distinct neck; peristome of 16 lanceolate, flat, smooth, rigid 
teeth, rarely cleft, sometimes none; spores smooth. Inflorescence 
monoicous. 
Distinctly separated from the rest of the species, being without 
a peristome, is S. Doniana or Donit Don’s bristle Moss. It is 
one of the most elegant of our minute Mosses, and probably often 
overlooked from its inconspicuous appearance. Of a gregarious
