  • Description

    Species Description - Rhizomes suberect, the caudices 2–3 cm diam.; fronds ca. 40 cm long; stipes darkened at bases, stramineous or faintly greenish distally, ca. 1/2 the frond length, to 20 cm x 2 mm, bases densely scaly, scales to 3 x 1.5 mm, flattened to somewhat inrolled, tan, but darkened toward the attenuate tips; blades green, ovatelanceolate, deeply pinnate-pinnatifid, to 20 x 13 cm; rachises abaxially with scales similar to those of stipes, but shorter; pinnae to ca. 10 pairs, sessile, largest 7 x 2.5 cm, deeply incised nearly to costae, proximal pinnae narrowed at their bases; segments approximate or even imbricate, entire to denticulate, tips rounded or subacute, margins ciliate with jointed hairs; veins simple, to 9 pairs per segment, reaching margins above sinus; indument on costae abaxially of sparse glands and dense, tan scales, these strongly inrolled at bases, darkened and attenuate at tips; laminae between veins glabrous on both sides of blades, or abaxially with sparse appressed, glandular hairs; sori inframedial, to 1 mm diam., exindusiate.

  • Discussion

    Type. Mexico. Chiapas: Mpio. Cintalapa, 16 km NW of Rizo de Oro, SE of Cerro Baul, Breedlove 21812 (DS! isotype NY!)

    This seems most closely related to Ctenitis tonduzii (Christ) R. M. Tryon & A. F. Tryon, from Costa Rica and perhaps Nicaragua (fide Stolze, 1981: 162), differing from that in having inframedial, exindusiate sori, approximate segments, and smaller, more decidedly inrolled scales on the blades. Moran (in Davidse et al., 1995) synonymized C. tonduzii under C. nigrovenia, but C. baulensis differs from C. nigrovenia in the more or less glabrous blade surfaces, inframedial sori, and approximate segments.

  • Distribution

    Terrestrial in montane rain forests; 1600 m. Mexico; Belize (reported by Rojas, 2001, but specimens not seen).
