Description: |
Rhizome c. 1 cm. in diameter; rhizome scales awl-shaped, ciliate, up to 1.5 cm. long, brown with a central black stripe. Sterile fronds lower part thick and spongy, upper part membranous, c. 45 × 30 cm., erect, oblong in outline, overlapping at the cordate base and forming a large thalloid mass, prominently veined in the upper 2/3, margin entire to irregularly wavy at the apex, covered at first with grey stellate hairs, becoming hairless with age. Fertile fronds 50 × 25 cm., broadly obcuneate in outline, apex rounded, margin entire to subentire, coriaceous, subglabrous above, densely set below with rufous stellate hairs c. 1 mm. in diameter. Sporangia covering a large oval area of about 25 cm. wide below the frond apex, densely set with brown stellate hairs similar to those on the lamina. |
Notes: | The fertile frond is broadly cuneate, lacking the ‘stag horns’ of the commonly cultivated species. |
