Ecology and Life History
Short General Description
Liverworts scattered or in small, pure patches, rather shiny, the spreading leaves golden-brown distally (green only at base) or purplish to blackish brown and appearing scorched; erect or strongly ascending, usually sparingly branched, but commonly with subfloral innovations. Stems slender. Rhizoids few, mostly near base, colorless or rose-colored. Leaves essentially transversely inserted and oriented, distant to laxly imbricate, spreading to strongly spreading or subsquarrose from a suberect, rather sheathing or concave base. Leaves ovate to oblong-ovate, somewhat shiny; leaves bilobed for approximately one third of their length, lobes acute or subacute, rarely blunt, ovate-triangular to triangular (Schuster 1974).
Reproduction Comments
This species is paroicous, a near synonym of monoecious meaning that antheridia are situated below the archegonia on the same branch (Crum 1991, Doyle and Stotler 2006).
