- Diagnosis
- Rhizomatous stem with dorsiventral symmetry, protostelic; stele surrounded by sclerenchyma formed by thick-walled fibers. The rhizome bears unbranched unicellular trichomes in sheltered areas, and bases of trichomes are persistent on other surfaces. Roots arising from the ventral side of the rhizome, fronds (petioles) arising from the dorsal side. Fronds with circinate vernation, dichotomous or pseudodichotomous, with at least one order of branching; petiole lacking epidermis (presence unknown), with a cortex and C-shaped endarch vascular bundle, the later completely enclosed by endodermis. Pinnules of Pecopteris type, alternate and free, with a longitudinally striate rachis, attached at acute angle along the entire base, margin entire and apex obtuse or acute, midvein distinctive, secondary veins emerging from the midvein, slightly curved and forked once, one
secondary vein entering from the rachis in the basal side of the pinnule; epidermis of pinnae with trichomes on both surfaces, epidermal cells puzzle-like, with interlocking undulating anticlinal walls, stomata anomocytic. Sori exindusiate, 3–5 on adaxial surfaces of the pinnules, consisting of 10–20 sporangia attached to a receptacle; paraphyses and scales intermixed with sporangia. Sporangia clavate with short stalk four cells thick, annulus formed by only one row of cells; stomium longitudinal; spores smooth and trilete.
