About Mickelopteris cordata (Hook. & Grev.) Fraser-Jenk.
Mickelopteris cordata (Hook. & Grev.) Fraser-Jenk. grows from short, erect rhizomes covered with narrow, brownish scales. This species produces two distinct types of fronds. Fertile, spore-bearing fronds typically have much longer stipes (frond stalks) than sterile fronds. The lamina (blade) of the frond is usually 3–6 cm (1.2–2.4 in) long and around 2–4 cm (0.8–1.6 in) wide, with a heart-shaped base and a somewhat rounded apex. The lamina is held at an angle to the stipe. The upper surface of fronds is brownish green, while the lower surface is brown. Mickelopteris cordata is native to the Indian subcontinent, including Assam, Bangladesh, India, and Sri Lanka; Indochina, including Cambodia, Laos, Myanmar, Peninsular Malaysia, Thailand, and Vietnam; south-central China, Hainan, the Philippines, and the Lesser Sunda Islands. It grows in damp locations at elevations below 1000 m, most commonly on wet soil and rocks in river valleys within dense forests and shrublands.
