Cuspidatula

Epiphytic or lithophytic, dioicous. Specialised asexual propagules absent. Stems procumbent to erect, irregularly branched, with two ranks of lateral leaves; branches emerging from ventral side of stem and with a collar of tissue at base or (not in Victoria) emerging laterally and without a collar of tissue at base. Leaves asymmetrically ovate to ovate-lanceolate with an acute, short-acuminate or piliferous, or (not in Victoria) rounded apex, succubous, alternate, imbricate, laterally patent when moist to secund in the direction of the adaxial stem when dry, entire. Leaf cells hexagonal, circular, elliptic or oblong, sometimes more elongate at apex and base, smooth, thin-walled to thick-walled, with large nodose and often confluent trigones, with 5–10 oil bodies; oil bodies ellipsoid to spherical, granular-botryoidal, colourless. Rhizoids scattered. Androecia spicate, with ventricose bracts, each with a single antheridium. Sporophyte terminal on stem, developing within a perianth and subtended by bracts; perianth ovoid, deeply plicate in apical three quarters, with entire (not in Victoria), crenulate (not in Victoria) or ciliate to laciniate mouth; bracts strongly differentiated from leaves, larger and usually more dissected, with 2–3 lobes and sometimes small teeth along margin, rarely unlobed (not in Victoria); capsule ovoid, 4–5-stratose; elaters bispiral; spores globose, papillose.
