Discusión taxonómica
Ctenitis bullata is closely related to C. strigilosa and is distinguished by its larger glandular indusia, inrolled scales 2–2.5 mm long on the rachises, similar scales (1–1.5 mm long), jointed hairs 0.3–0.7 mm long, glands along the costae abaxially, scattered jointed hairs 0.5–0.8 mm long adaxially on the glandular costae, and scattered jointed hairs and rare glandular hairs on both sides of the blades, between and on the veins.A
