--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>large, in thick mats or deep wefts, yellow-green to dark green, glossy. <b>Stems</b> irregularly branched. <b>Stem</b> leaves ovate-lanceolate to cordate-ovate; base rounded to subcordate, slightly decurrent; margins revolute, serrate, serrulate, or denticulate; apex acute, acuminate, or abruptly acuminate; costa subpercurrent, with 2 or more shorter, supplementary costae at base; alar cells quadrate to transversely elongate, region extending nearly to costa and an equal distance distally; laminal cells smooth; medial cells uniformly linear-flexuose; apical cells oval-rhombic. <b>Branch</b> leaves similar, narrower, smaller, 2–3 × 1 mm; margins more strongly denticulate; apex narrower, flagelliform, smaller; costa weaker. <b>Specialized</b> asexual reproduction absent. <b>Perigonia</b> on secondary stems or sometimes on side branches, leaves deltoid-apiculate. <b>Perichaetia</b> on primary stems, leaves ecostate. <b>Seta</b> short. <b>Capsule</b> exserted, cylindric, oblong-cylindric, or oblong-ovoid; annulus scant or absent, adherent; operculum oblique-rostrate; exostome teeth subulate, trabeculate or papillose; endostome basal membrane absent, segments weakly developed, narrowly subulate, papillose.</span><!--

--><p>The stems of <i>Antitrichia</i> are densely foliose and internally divided into a strong 4–6-layered cortex of incrassate cells and a medulla of loose, thin-walled cells. The branches are procumbent or pendent, somewhat plumose, and usually elongate, with deltate to subfoliose pseudoparaphyllia investing the branch buds; the central strand is rudimentary or absent. The stem leaves are concave and 2–3 × 1–1.5 mm; the basal laminal cells are rounded-quadrate to elliptic, in a region filling the basalmost angles and extending up most of the margins. The endostome segments are fragile, evanescent, and 1/2–3/4 the exostome teeth length.</p>
