Description
The specific epithet ludens comes from the Latin word, ‘ludo’ meaning play which refers to the variability division of the lamina. Calciphilopteris ludens have long creeping rhizomes measuring 4-10 cm long with 2-3 mm thick and densely scales at the apex. Ferns have two types of fronds, sterile and fertile fronds. The fertile frond stipes (9-38 cm) of C. ludens are longer than sterile fronds (5-35 cm). This species has a pedate lamina structure where the leaf is divided into several lobes with dark green above and copper green beneath (Nor-Ezzawanis, 2020).
Calciphilopteris ludens occurs in Australia, China, Flores, India, Indochina, Java, Peninsular Malaysia, Sumbawa and Thailand. However, in Peninsular Malaysia, the species recorded only in limestone hills in Kedah and Perlis from sea level to 65 m altitude (Nor-Ezzawanis, 2020).
