secund, nerve single ; areolze linear, and the following species are 
dioicous, with the stems and branches strongly hooked at apex. 
7. aduncum, the claw-leaved Feather Moss, fruiting in April and 
May on marshes and marshy heaths ; also on swamps and marshes, 
fT, exannulatum, its capsules ripening in June. 
Found on bogs are 4. Sendtneri, H. vernicosum, H. Cossoni, and 
LZ. lycopodioides. 
Monoicous Mosses, with branches and stems scarcely hooked, 
are H. fluitans, the floating Feather Moss, and A. vevolvens, the 
twirling Feather Moss, fruiting in April and May on bogs and 
marshes, &c. 
Hf. uncinatum, the sickle-leaved Feather Moss, fruits in May 
and June on sub-alpine walls and rocks. 
‘In section III. the stems are regularly pinnate and radiculose ; 
leaves thickly nerved, opaque ; capsules arcuate. ‘The five species 
in this section fruit in April and May, and frequent marshes, wet 
rocks, &c. . commutatum, the curled Feather Moss; AH. fiiiainum, 
the lesser-golden fern Feather Moss ; and #. falcatum, the falcate 
Feather Moss; . sulcatum, and H. virescens, are very rare. 
ff. rugosum, the wrinkle-leaved Feather Moss, is the only species 
in section IV. The stems are two to three inches, robust, without 
radicles; and irregularly pinnate; leaves lanceolate-acuminate 
from a broad base, dry, shining and strongly wrinkled or crumpled ; 
areolation narrow and wavy above, the rest small quadrate; cap- 
sules sub-arcuate ; lid rostrate, aznulus broad. Found on lime- 
stone and other rocks, but barren in England. 
In section V., . zuzcurvatum, the incurved Feather Moss, has 
stems creeping, czespitose, and pinnate; leaves ovate-lanceolate, 
tapering, all pointing upwards, entire, shortly two-nerved ; capsules 
small, ovate ; ripening in June and July on shady walls and stones. 
The species not yet referred to in section VI. are all very rare, 
viz.: HZ. canaricuse, H. hamulosum, H1. callichroum, H. Bambergert, 
and 7. imponens. HH. patientie is not uncommon on clay soils. 
Section VII., 4. molluscum, was described in the notes for last 
November, and section VIII., . crista-castrensis, in those of the 
previous August. 
In section IX., the stems are soft, ccespitose, prostrate and 
branched ; leaves falcato-secund, faintly nerved, areolce linear ; 
capsules incurved cernuous ; lids mammillate. With the exception 
of 4. ochraceum, the yellow mountain-rill Feather Moss, which is 
dioicous and is found on stones in streams; all fruit in May and 
June, and are monoicous. 
Hi. palustre, the marsh Feather Moss, is found on rocks and 
stones in streams. 4. dilatatum and A. eugyrium are rare ; and H. 
molle, the soft water Feather Moss, and AH. Arcticum, the Arctic 
Feather Moss, are very rare.
