3. Hypopterygium Brid. 孔雀藓属 kong-que xian shu
Bryol. Univ. 2: 709. 1827.
Plants creeping, usually with brown rhizoids. Primary stems creeping; secondary stems erect with remote scale-like leaves or nudicaulous, rarely with dense brown rhizoids, erect-spreading above, 1–2 pinnately branched, rarely 3 pinnately branched, often peacock tail-like. Lateral leaves broadly ovate, oblong or ovate-ligulate, asymmetric; leaf margins mostly bordered by narrowly elongate cells, serrate above; costa single, vanishing below leaf apex; laminal cells rhomboidal or oval-hexagonal, loose, smooth, thin- or thick-walled, gradually becoming longer and looser toward leaf bases; amphigastria appressed, broadly ovate or ovate, symmetric, with long apex, margins bordered. Dioicous or autoicous. Inner perichaetial leaves slightly longer or sheathing at the base, with
acuminate apex, margins entire. Setae elongate, slender, smooth, sometimes twisted; capsules ovoid or elongate-ovoid, horizontal or pendulous; annuli wide, caducous or persistent; peristome double; exostome teeth weakly keeled, densely striate; endostome segments wide, well developed, basal membranes high; cilia 2–3. Calyptrae smooth, mitriform or conical. Spores minute. Gemmae numerous, often growing on branches.
