Thelypteris pozoi (Lag.) C.V. Morton

Common name


Rhizome shortly creeping, then erect, up to 3 mm in diameter; rhizome scales up to 1.5 mm long, dark brown, lanceolate, margin ciliate. Fronds tufted, arching, not proliferous, softly herbaceous. Stipe up to 28 cm long, pale brown, thinly set with short white hairs and a few brown scales basally. Lamina up to 46 × 25 cm, narrowly elliptic to ovate-lanceolate in outline, 2-pinnatifid, apex tapering to a point with pinnatifid terminal segment, basal pair of pinnae somewhat reduced and deflexed. Pinnae narrowly oblong, 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.
