Cheilanthes notholaenoides Maxon ex Weath.
Descripción
Rhizomes short- to long-creeping, horizontal, ca. 2 mm diam.; rhizome scales linear-lanceolate, 4 mm long, concolorous, orangetan or becoming dark in center at base with age, margins entire, rarely the scales entirely black, sclerotic, with a few marginal hairs, some specimens with rhizome hairs showing among the scales; fronds to 40 cm long, distant; stipes 1⁄4–2⁄5 the frond length, black, lustrous, terete, with orange-tan to brown appressed filiform scales 1.5 mm long, mostly only 2 cells wide; blades lanceolate to narrowly deltate, 2-pinnate, subcoriaceous, the pinnules usually auriculate or each with a free acroscopic lobe; adaxial surfaces glabrous, bluish to whitish green, pebbly; abaxial surfaces with dense filiform scales 1–2 mm long, 2 cells wide on costae with sparse to scattered minute hairs 0.1 mm or less on segments, rarely glabrous; laminar margins somewhat curved, only slightly modified into 0.3 mm wide false indusia, slightly paler at margins, not decurrent, margins papillose; spores tan; 2n=174 (Oax).A

Discusión taxonómica
This species is confused with Cheilanthes microphylla, but the latter has white 0.2–0.5 mm abaxial laminar hairs and dense short hairs on the rachises adaxially and rachises abaxially glabrous or with only sparse hairs. Cheilanthes notholaenoides has uniform hairs adaxially and abaxially on the rachises, and the laminae are glabrous or with scattered jointed hairs 0.3–1 mm versus the short white hairs of C. microphylla.
Cheilanthes notholaenoides is especially close to C. cucullans in the abundant stipe and rachis hairs and often long-ciliate rhizome scales, but the former is distinct in being only bipinnate (vs. bipinnate-pinnatifid) and coriaceous (vs. chartaceous). Not previously reported from the United States (Windham & Rabe in FNA Ed. Comm. 1993), a specimen from Texas (s. coll., s.n. “Ex herb. Bennett”) is at NY.A
