Discusión taxonómica
Ctenitis strigilosa is distinguished by the pinnate-pinnatifid to usually barely bipinnate blades, numerous dark hair-like scales on the stipes and rachises, small indusia, and densely glandular rachises, costae, veins, and laminae (both sides of blades). It is closely related to C. bullata, which see.A
