- Stem unknown. Leaves ovate to ovate-lanceolate gradually tapered to
acute apices, slightly rounded to base; margin entire, bordered by unistratose, 2(–3)-seriate limbidium, limbidium cells separated by oblique cell walls; laminal cells dimorphic: the narrow darker cells forming loops embracing several cells, often 7 in a specific pattern (3 + 1 + 3), but in more cases with additional cells, so the areolation often looks composed of a fairly irregular loops of 4 to 20 cells; costa stout and broad, multistratose, disappearing below leaf apex, without lateral branches. Brood bodies unknown.
