Description
Dryopteris sparsa is a terrestrial, lithophytic or, rarely, epiphytic fern, with erect rhizomes. The apex is scaly. The scales are ovate, 5-8 mm long, papery and pale brown in colour. The fronds are tufted. The stipe is 20-45 cm long, by 25-38 cm wide, chartaceous and dull pale green on both surfaces. The apex is abruptly acuminate. The rachis is glabrous, covered with small, elongated protuberances. The ultimate segments are 5-15 mm long and 3-10 mm in diameter. The base is asymmetrically cuneate. The margins have rounded lobes and 1 or more short teeth on the upper side of each lobe above the sinus between the lobes. The veins are forked 1-3 times. The sori is medial on the vein branches. The indusium is reniform and fawn. The fronds of D. sparsa are exceptionally brittle (Jones, 1998).
