Dioicous; in large, soft, dense, pale green tufts, light brownish- 
yellow below. Stems simple or dichotomous, 6-10 in. high, 
whitish, with three layers of thin cuticular cells, free from fibres 
and pores; cells of the peripheral layers yellowish white. Cauline 
leaves broadly obovate-lingulate, minutely auricled, the apex trun- 
cate and slightly eroso-fimbriate; hyaline cells in upper half 
rhomboid, at middle base flexuose-rhomboid, thence to margins 
very narrow, flexuose-linear, free from pores and fibres, or with a 
few faint fibres in the upper part. 
Branches crowded, 3-5 in a fascicle, 1-2 patulous, arcuato- 
decurved, the rest slender, greatly elongated, appressed to stem; 
the retort cells small, cylindric, perforated at the scarcely projecting 
apex. 
Ramuline leaves densely crowded, indistinctly 5-ranked, when 
moist turgidly imbricate, when dry erecto-patent, opake, concave, 
widely ovate-acuminate; the apex broadly truncate, with 6-10 
minute, unequal, obtuse teeth; the margin incurved in the upper 
two-thirds, and with a faint border of two rows of extremely 
narrow cells; the hyaline cells annulate-fibrose, minutely and 
Sparingly porose, the chlorophyllose cells enclosed by the hyaline, 
much compressed; leaves of the pendent branches with the apex 
rounded and indistinctly toothed. Capsules seated in the coma or 
upper fascicles, on a thickish white peduncle; the perichetium 
inflated, oblong, whitish; lower bracts ovate-acuminate, muticous, 
middle broadly ovate-oblong, innermost broadly oblong, deeply 
concave and often cucullate at apex, all with very narrow linear 
areolation, quite free from fibres and pores. Spores ferruginous. 
Male plants growing in the same tufts with the female, more 
slender, the amentula short, ovate, closely imbricated, pale 
greén, crowded in the coma; bracts roundish ovate, in the lower 
part of lax wide curved non-porose cells, often free from fibres,
