MOMs ON MOSSES: 
By WILLIAM STANLEY. 
(Concluded from page 219.) 
Pseudoleskea catenulata, the filiform Feather Moss, grows in dense 
patches about half-inch in height, on alpine and sub-alpine rocks ; 
the leaves are very minute, being scarcely visible to the naked eye ; 
widely ovate ; acute, entire, concave, margin reflexed below ; nerve 
broad, ceasing a little more than half way up ; fruit not found in 
Britain. 
Plagiothecium latebricola, the lurking Feather Moss, fruits in 
winter on moist shady woods on decaying trunks, and also old 
stocks .of Aspidium filix mas growing generally in company with 
HI, denticulatum, in yellowish or bright green tufts, with slender 
stems about quarter-inch in height ; leaves ovate-lanceolate, taper- 
ing to an acute point, faintly two-nerved at the base; capsules 
elliptic-oblong, turbinate when dry; lid short, acutely conical. 
Two rare species of Plagiothecitum are P. Miihlenbeckit, found on 
alpine rocks in Scotland ; and P. Svlestacum, found only in Kent 
and in Yorkshire. 
Amblystegium serpens, the creeping Feather Moss, is very 
common on walls, moist banks, trunks of trees, &c., and is known 
from its allies by its small size and slender habit, and by the small 
acutely tapering leaves, usually nerved half way ; capsules oblong- 
cylindrical or obovate, cernuous, ripening in April and May; lid 
conical, acute. A. radicale, the long-stalked creeping Feather 
Moss, is found on moist ground amongst grass. A. zrriguum, the 
rigid brook-side Feather Moss, is found on stones in rivulets and 
streams. A. fluviatile, the soft brook-side Feather Moss, is found on 
rocks and stones in mountain streams ; and A. 77farzum, the short- 
beaked Water Moss, on stones near pools, sometimes in water. All 
fruit in April and May. 
Four species, very rare, being found only on rocks, near the 
summit of Ben Lawers, are Zhuidium decipiens, Brachythectum 
plicatum, Fleterocladium dimorphum, and Hypnum Hallert. 
With the exception of the first six species, the leaves of which 
are squarrose, the sub-genus, ypxum, is distinguished by its falcato- 
secund character and narrowly linear areolation. 
Of the squarrose section still unmentioned, and all fruiting in 
May, are 4. polymorphum, the dwarf starry Feather Moss, found 
on limestone walls, banks and rocks, and in wet swampy places 
and bogs. . elodes, the fine leaved marsh Feather Moss, and Z. 
polygamum, the cluster-flowered Feather Moss. 
In section II. the stems are pinnately branched ; leaves falcato-
