NOTES ON MOSSES. 257 
Section X. has stems simple, more or less pinnate, erect or pro- 
cumbent ; leaves patent, thinly nerved or shortly two-nerved ; 
areolce linear ; capsules incurved, cernuous. 
HZ. cordifolium, the heart-shaped Feather Moss, inhabits marshes 
and ditches, fruiting in April and May. ‘The stems are from three 
to six inches, erect, bright green above; reddish-brown below ; 
leaves convolute and cuspidate at tip of branches ; cordate-ovate, 
obtuse or slightly apiculate, strongly nerved almost to apex ; cap- 
sules oblong, suddenly horizontal, not tapering at base ; lid conical. 
HI. stramineum, the straw-like Feather Moss, although rare in 
fruit, is common in marshes amongst Sphagnum. 
HZ. trifarium, the three-ranked Feather Moss, is found only in 
Scotland on alpine bogs and rills where the soil is turfy. 
HT. scorpioides, the scorpion Feather Moss, frequents bogs, but is 
not common in fruit. It is one of the largest species of the genus, 
having stems four inches long or more ; leaves crowded, imbricate, 
falcato-secund, large, roundish-ovate, apiculate, entire, nerveless or 
faintly two-nerved ; capsules short, oblong curved, cernuous on a 
fruitstalk two inches long ; lid conical, pointed. Fruits in May. 
LTylocomium splendens, the glittering Feather Moss, is frequent 
on grassy banks, in woods, &c., but rare in fruit, which ripens in 
April. The stems are two to six inches in length, erect, and 
bitripinnate ; leaves roundish-elliptical, with long wavy points, 
serrate, shortly two-nerved, margin recurved below ; capsules ovate, 
curved, cernuous ; lid convex, tapering into a long beak ; dioicous. 
Leckera pennata, the feathered Neckera, is distinguished from the 
other British species by the immersed capsules, and by the in- 
florescence. It is very rare, being only found on the trunks of a 
beech tree at Fotheringham, near Forfar, and at Colin Glen, near 
Belfast. 
Another Moss, with concealed capsules, is Cryphea heteromalla, 
the lateral Cryphzea ; it is found on trunks of trees; a variety, B, 
aquatilis, has been found on stones in running water. Stems one inch 
in length, sparingly branched, sub-pinnate ; leaves spreading, im- 
bricate, slightly recurved, broadly ovate, concave, margin reflexed, 
nerved above half-way ; capsules unilaterally inserted, oblong ; lid 
conical, pointed : synoicous.
