Ctenitis

Taxonomy
Christensen's original study was confined to the species of tropical America. The first surveys of allied species in Asia were made independently by Ching (1938) and Ito (1939), both of whom failed to notice the significance of scale-structure and glands which separate Ctenitis (as here defined) from Tectaria and other genera. Copeland (1947) added other species which are here included in Tectaria. Holttum (1985) prepared a list of 47 Old World species included in Ctenitis by previous authors but not conforming to the present generic concept.
