Common name


Rhizome shortly creeping, then erect, up to 3 mm in diameter; rhizome scales lanceolate in outline, up to 1.5(1-5?) mm long, margin ciliate, dark brown. Fronds monomorphic, tufted, arching, not proliferous, softly herbaceous. Stipe up to 30 cm long, pale brown, thinly set with short white hairs and a few brown scales basally. Lamina up to 46 × 25 cm, 2-pinnatifid, narrowly elliptic to ovate-lanceolate in outline, apex tapering to a point with pinnatifid terminal segment, basal pair of pinnae somewhat reduced and deflexed, lower 4-8 pairs of pinnae free; pinnae 12-15 pairs, narrowly oblong in outline, base truncate, incised three quarters of the way to the costa into broadly oblong ultimate lobes, apex rounded, margin lobed; both surfaces hairy, more so along the veins, costa and costules; veins not meeting below or rarely touching at the sinus or one vein ending in the sinus and the other slightly above it; rhachis strawcoloured, with short and long white hairs. Sori oval to linear along the veins, up to 2 mm long; exindusiate.


Could be confused with species of the genus of Diplazium, but they have much larger fronds (up to 2m).
Stegnogramma pozoi look for: linear sori!


pozoi: first collected by D.G. del Pozo in nothern Spain.
