Dinckleria

Epiphytic, lithophytc (not in Victoria) or terrestrial (not in Victoria), dioicous. Specialised asexual propagules absent. Stems differentiated into creeping stems with reduced leaves and stems with normal leaves, diverging from the substrate and sparingly and irregularly branched, with two ranks of lateral leaves and often a rudimentary rank of underleaves; branches emerging from abaxial side of stems and with a collar of tissue at base when creeping and microphyllous, and emerging laterally and with or without (not in Victoria) a collar of tissue at base, or (not in Victoria) from abaxial side of stem and with a collar of tissue at base on normal leafy stems. Lateral leaves asymmetrically ovate to elliptic or narrowly obovate (not in Victoria), often 2–3-lobed, alternate, remote to imbricate, succubous, directed toward stem apex and spreading laterally, dentate throughout or sometimes only near apex (not in Victoria), revolute in basal half. Underleaves absent, bifid or filiform, remote. Leaf cells polygonal to quadrate or rectangular, papillose, thin-walled, with small trigones, with 2–6 oil bodies; oil bodies ellipsoid, granular, grey to brown. Rhizoids scattered on creeping stems or (not in Victoria) confined to underleaf bases on normal leafy stems. Androecia becoming intercalary, with 2–8 pairs of leaf-like ventricose bracts, each with one antheridium. Sporophyte terminal on main stem, developing within a perianth; perianth obovoid (not in Victoria) or ellipsoid to obloid, pluriplicate or non-plicate (not in Victoria), with ciliate to dentate mouth; capsule globose, 5-stratose; elaters bispiral; spores globose, echinate.
