Flowers and fruit unknown: in dull green cushions with stiff, 
erect stems 2-2.5 cm. high, in cross-section showing two to four 
rows of outer, thick-walled, golden brown cells and no central 
strand; stem-leaves 3.5-4 mm. long and I mm. wide, when dry 
obliquely incurved or appressed-imbricate, forming a compact 
bud at apex of stem showing the conspicuous, glossy, whitish 
costae, the leaf either oblong-ovate or slightly obovate, the base 
more or less yellowish; leaf-margin incurved when dry, not thick- 
ened, papillose on border, otherwise entire or slightly denticulate 
at apex; costa percurrent, broad and yellowish at base, about 
300 « wide and one third the width of leaf, tapering gradually to 
apex, in cross-section near middle showing about seven guide- 
cells with stereid bands above and below of about equal size and 
outer cells scarcely or not differentiated; cells throughout upper 
part of leaf more or less hexagonal, scarcely elongate, on upper 
side mostly mamillate and unipapillate, on under side papillate; 
cancellinae of leaves growing from below the apex of stem distinct, 
broad, extending about one third up leaf and terminating in rather 
acute angles; cancellinae of inner leaves at apex of stem rather 
ill-defined and leaf-cells on either side of costa just above the 
cancellinae mostly covered with a dense, green mass of filiform

Dioicous, male plants about like the fertile, with often several 
antheridial buds aggregate near the apex of stem, the antheridia 
few, without paraphyses, enclosed by several short, ovate, ser- 
rulate, costate, brownish leaves: in compact, green tufts, showing 
the conspicuously white leaf-bases, with branching stems I-3 cm. 
high; stem-leaves more or less twisted and crispate when dry, 
from an obovate or oblanceolate, nearly or quite entire, erect 
base narrowed to a linear-lanceolate or nearly linear, deeply 
grooved point from mostly as long to about twice longer than basal 
part, with a hyaline or yellowish border, entire except at the 
broadly acute, denticulate apex; costa not quite percurrent, smooth
