Original diagnosis/description

A crescent-shaped group of 5 fronds closely adhering together, fronds flat, elliptic to broadly elliptic, 3-6.5 mm long and 2.5-4 mm wide (length/width ratio 1.4-1.5), with a rounded spot (node) near the base (about 1/7 of the frond length) well within the lamina, from which three faint lines (veins) run towards the apex without reaching it. Roots not preserved. Some fronds still in the original position of budding.

Etymology

Named in honour of my friend, the late Čestmír Bůžek (1933-1992), for his activities in the North Bohemian palaeobotany.
