short oblong cells, 13# wide by 224 long, varying in width from 
1o to 15 andin length from 18 to 254, sometimes below these is 
a row of slightly inflated and elongated cells across the base 20 
to 26 wide by 40 to 50y long, the cells in the one or two mar- 
ginal rows at the base frequently much elongated, reaching 100p, 
in all parts of the leaf above the basal eighth cells prosenchyma- 
tous, in the middle region linear, 8.34 wide by 49» long, ranging 
in width from 6.5 to gu, and in length from 4o to 56p, im the 
apical region shorter, slightly wider and more or less irregular, oval, 
hexagonal or rhomboidal, 8.6 wide by 23.5" long; outer peri- 
chetial leaves triangular, reflexed from the middle, the inner 
lanceolate or oblong, erect, all acuminate, costate, costa vanish- 
ing in the acumen, entire. 
Sporophyte medium, 1.5 to 25° long: seta brown below, paler 
above, slender; capsule light brown when old, 1.5 to 2™™ long, 
cylindrical, oval or obovate, asymmetric or rarely almost sym- 
metric, from erect to incurved, not constricted under the mouth 
when dry; collum one-sixth to one fourth the length of the spo- 
rangium ; cells of the exothecium irregular, mostly parenchy- 
matous throughout, somewhat prosenchymatous on the convex 
side, cells on the concave side 324 wide by 50» long, varying in 
width from 15 to 47m and in length from 21.5 to 77#, on the 
convex side 284 wide by 62 long ranging from 13 to 38.5# wide 
and from 25 to86u long ; three to six rows of cells under the mouth 
transversely elongated, hexagonal, 21.5 to 43 wide by 8.6 to 
25.8 leng; cells walls 3 to 4m thick; stomata twenty to thirty 
to the capsule, scattered, 324 wide by 38 long ; peristome teeth 
narrowly lanceolate, brown below, pale above, narrowly margined, 
transversely striate on the back below the middle, papillose above, 
serrulate above; endostome pale, papillose throughout, faintly so 
on the membrane, this only one half the length of the segments, 
segments linear lanceolate, carinate, open along the keel between 
the articulations, cilia one or two, short, one half the length of 
the segments, nodulose; operculum conic; annulus narrow, of 
one row of cells: spores finely puncticulate, 13 to 184 in diameter : 
calyptra not seen.
