At least bipinnate fronds. Rachides and veins bearing spines or spine bases. Ultimate pinnae alternate, elongate–linear in outline, more or less symmetrical. The basalmost acroscopic pinnules of ultimate pinnae laminar and aphleboid. Pinnules alternate, decurrent, up to ~1 mm wide and ~3 mm long, connate in the basal third of the pinnule lamina. Pinnules with a single midvein that bifurcates once close the pinna rachis; resulting veins similar in thickness to midvein, and each running towards and terminating in an acute tip at the distal pinnule margin.
This species is named in honour of Frank Löcse, who found the specimens and initiated manifold research activities in the Flöha Basin.
