Thelypteris hispidula (Decne.) Reed
Thelypteris quadrangularis (Fée) Schelpe
Common names:
Frequency: Rare
Status: Native
Description:
Rhizome erect or inclining, c.20 mm in diameter; rhizome scales up to 6 mm long, dark brown, lanceolate, often thinly pilose. Fronds tufted, arching, not proliferous, herbaceous. Stipe up to 40 cm long, pale brown, thinly set with minute stiff hairs. Lamina up to 59 × 30 cm, ovate to broadly lanceolate in outline, deeply 2-pinnatifid, apex tapering to a point with a pinnatifid terminal segment, basal 2 pairs of pinnae slightly reduced and deflexed. Pinnae linear-oblong, apex tapering to a point; ultimate lobes narrowly oblong, slightly falcate, apex rounded, basal acroscopic lobe enlarged; both surfaces with long, white hairs, more so below, particularly along the veins, costae and costules; veins 1 pair meeting some way below the sinus. Rhachis set with long pale hairs. Sori round, up to 13 per lobe; indusia coriaceous, thickly set with long white hairs.
Notes: Christella hispidula resembles C. dentata but the latter has 1 pair of veins meeting below the sinus and a single vein joining in the sinus and a clearly creeping rhizome.
C. hispidula look for: 1 pair of veins meeting below the sinus, 1 or 2 pairs of slightly reduced pinnae and an erect to inclining rhizome.
