140 JUNGERMANNIACEAE 
Green or yellowish-green, intricately caespitose or straggling 
among other bryophytes: stems rather rigid, 4-20 mm. long, . 
.27 mm. in diameter, with often copious lateral or dichotomous 
branching, cortical cells subopaque, 7—14-seriate, 28-96 px I5- 
32 и, axile cells 4-12-seriate; root-hairs infrequent: leaves close 
or somewhat widely spaced, erecto-patent or suberect, divided 
nearly to the base into 3 or 4 rigid setaceous laciniae (occasionally 
five or in very slender conditions rarely reduced to two), these .4- 
.65 mm. (8-13 cells) long, usually connate for 14—34 the height 
of the basal cells, or sometimes with a basilar membrane one cell 
in height; leaf-cells 40-70 их 16-32 и, 117—214 times as long as 
broad, thick-walled, the septa usually strongly thickened toward 
the periphery and slightly protuberant, giving the laciniae a some- 
what nodulose outline ; cuticle granulate or striatulate : underleaves 
similar to the lateral leaves, their laciniae commonly one or two 
cells shorter : paroicous, or with antheridia on the same axis buta 
little removed from the 9 bracts, or sometimes dioicous: 4 bracts 
with a narrow basal membrane, the laciniae usually once furcate; 
antheridia about .15 mm. in diameter, the short stalk composed 0 
a single row of cells: archegonia 4-7: 9 bracts 4—6-lacimiate | 
with a basilar membrane 2-6 cells high, the laciniae furcate of often - 
with an antler-like ramification : perianth highly exserted, cylin- 
drical or pyriform-cylindrical, 1.5-2.2 mm. х.45--8 mm., in ated, 
with usually one or two deep furrows toward the apex, the rather 
wide mouth somewhat abruptly drawn together and fringed with 
long, mostly connivent cilia : calyptra thin, free, about half as long 
as the perianth : capsule ellipsoid-oval, .6-.0 mm. long, the valves 
bistratose, the cell-walls of the outer layer with purplish-brow? — 
columnar thickenings, those of the inner layer with similar thicker 
ings and with imperfect semiannular fibers; seta 5-12 mm. 100 f : 
foot deeply penetrating the stem-apex, descending to the plane 0 : 
insertion of the third set of bracts ; spores 14-18 /4, minutely grant- 
late-papillate ; elaters 1 30-300 их 9-11 p. |
