Plants 1–2 cm, bright green, yellow-green, or bronze, somewhat glossy. Stems without stipe, simple or rarely branched. Stem-leaves not seriate, appressed when dry, spreading when moist, oblong-lanceolate to oblong-ovate, plicate; base not auriculate, somewhat decurrent; margins revolute from mid alar region just proximal to apex; costa single, 2/3 leaf length; alar cells well differentiated, oblate, region large, conspicuous; medial laminal cells linear-flexuose, 1-papillose or rarely smooth, walls ± porose. Branch leaves when present, similar to stem-leaves. [Seta 0.6 cm. Capsule short-cylindric; operculum unknown]. Calyptra unknown.

Distribution

Fla., Mexico, West Indies, Central America, South America, se Asia, Africa

Discussion

Species 1.

Henicodium is distinguished by mostly simple, erect stems with revolute-margined leaves. The laminal cells are 1-papillose (individual leaves may sometimes be smooth) and the costa ends well before the leaf apex. Gemmae are regularly produced on older stems in large clusters in distal leaf axils.
