346 THE NORTHERN MICROSCOPIST. 
rical, tapering above on a rough seta; lid conical, obliquely 
beaked: dioicous. Fig. 45. 
Belonging to the smooth-stalked division is Zurynchium striatum, 
the common striated Feather Moss ; found in woods and on shady 
banks, and having stems loosely tufted, arched and sub-pinnate ; 
branches drooping ; leaves gradually tapering from a broad cordate 
base, squarrose, serrate, striate, nerved more than half way; 
: capsules almost cylindrical, curved, cernuous; lid large, with a 
long slender curved beak: dioicous. 
Somewhat rare on shady limestone rocks and roots of trees is the 
lesser-striated Feather Moss, £. striatulum, being smaller in all its 
parts than the previous species. Z. speciosum, the showy Feather 
Moss has an ovate capsule on a rough seta, and lid with a long 
i. pointed beak ; leaves ovate, serrulate, nerved almost to acute apex, 
- bright green ; on stones near springs, and sometimes in water. 
| The family eckeracee is noticeable from having been named 
after MVecker, a celebrated botanist who denied the existence of 
sexes in Mosses. 
It has the fructification truly lateral; dimidiate calyptra and 
double peristome; the inner one of 16 cilia. 
: The capsules are oval-oblong immersed or pedicillate; lid 
| obliquely rostrate ; outer teeth 16 linear, subulate, long connivent 
: into a cone; stems pinnate; leaves complanate. 
The only species not fruiting this month is 1. pennata, the 
Feathered Neckera. Found in Ireland and the East Highlands of 
Scotland, it fruits in spring, and is collected on the trunks of trees. 
LV. complanata, the flat-leaved Neckera, inhabits trunks of trees, 
walls, &c., and has been found in fine fruit in Millers Dale. It 
has leaves complanate, ovate-oblong, and suddenly apiculate 
from a broadish apex, faintly and shortly two-nerved; capsules 
roundish elliptical, tapering below, erect; lid large, obliquely 
rostrate: dioicous. 
NV. crispa, the crisped Neckera, from the undulate character of its 
leaves has stems 4—6 inches, pinnate from a creeping rhizome, 
and leaves serrulate at apex; mountainous rocks and trees: 
dioicous: Fig 46, 
In similar situations is VV. Pumila, the dwarf Neckera, with a 
variety B Philipeana. 
Consisting of large and beautiful mosses, as may be inferred 
from its including a “ gigantea” and “ splendidissima” among its 
foreign relations is the genus Hfookeria, named in honour of Sir W. 
J. Hooker ; to whom British muscologists are much indebted for 
the zeal and ability with which he has investigated both mosses 
and hepatics. With the exception of Z. letevirens, which is very 
rare and found only at Mousehold Cave, in Cornwall, and at two 
stations in Ireland; the only species representing this genus is
