Description:
Species Description - Rhizomes terrestrial, small, erect, bearing narrow, almost filiform scales; fronds few, fasciculate, the stipes green toward apex, delicate, ridged but hardly winged, longer than the blades; blades triangular in outline, 4-8 cm long, 5-9 cm broad, acuminate, toothed at the elongate apex, simply pinnate, the rhachis green; pinnae 1-3 pairs only, the basal pair much the largest, basiscopically developed, petiolulate, pinnatifid, long-acuminate, deeply lobed at base, the two basal lobes often nearly free; veins forked; indusia broad, delicate, ciliate; leaf tissue herbaceous, light green, septate-hirsutulous on both sides, especially on the veins.
Distribution and Ecology - Florida, West Indies; Mexico to Brazil. Common and widespread in Venezuela (Sucre, Distrito Federal, Aragua, Yaracuy, Merida) at elevations up to 1300 m.

Discussion:
Asplenium anthriscifolium Jacq. Coll. Bot. 2: 103, t. 2, /. 3, 4. 1788. Type from Martinique (holotype W, fragment BR, photograph 7300) . Although Jacquin cited a Plumier plate he also had a specimen in hand, which should take priority as the type. It has generally been assumed that Swartz’ publication has priority over Jacquin's, but this has not been demonstrated.
This species is easily recognized by its small, triangular, basiscopically developed blades on stipes longer than the blades, and by the septate hairs that occur on the rhachises and veins.
Type. Jamaica, Swartz (holotype S, photograph by Maxon, US, labelled by Swartz “A. pusillum,” which was either a slip or else a first choice for name
