Discusión taxonómica
This differs from other small, pinnate-pinnatifid and bipinnate species of Ctenitis by the large indusia, blades lacking glandular hairs abaxially, and the blackish, strongly clathrate costal scales. The blades are dark green and tend to be fully bipinnate proximally and the pinnules obtusely lobed. Nearest allies are uncertain.A
