Emended diagnosis

Bodnar et al. (2020: Geobios (Lyon), 60: 9):
Apetiolate triangular to fan-shaped leaf, with very narrow base, leaf basal angle between 20° and 35°, lateral margins entire and straight or arched. Lamina deeply dissected symmetrically, above its basal third, forming slender distal segments, up to 0.1–0.2 cm wide. Apices of distal segments truncate. Veins dichotomizing and irregularly anastomosing on the whole lamina, forming narrow and long areoles. Venation density up to 4 veins per segment.
