||Usually epiphytic, small to medium-sized usually epiphytic; rhizomes creeping, 4-7 mm diameter, covered with tan to brown, linear-lanceolate scales.
||Fronds 13-80 cm long; stipe slender, 1.5-2.5 mm wide, brown, glossy, hairs (including glandular hairs) occasional to many, scales only at base, linear-lanceolate, often falcate, tan to brown, never proliferous; blade 1-pinnate, variable, oblong-lanceolate, narrowed slightly at base, dark green, glossy, chartaceous, glabrous except for scattered fibrils; rachises nearly glabrous to well covered with glandular hairs; pinnae 15-35 pairs, short-stalked, attached at proximal margins of bases, notched or incised, dentate or serrate (proximal 1/4-1/2 of lower margin often entire), not lobed (occasionally cut into narrow lobes), 1.5-12 x 0.3-1.2 cm, lower margins perpendicular to rachises, upper basal margins parallel with rachises or angling slightly, tips long, acuminate, narrow; veins at first lying near costae, then curving outward at middle of pinnae and ending in marginal teeth.
||Sori in rows parallel to and nearly contiguous with costae, and often with each other, bilaterally, overlapping in older pinnae, 6-16 mm long, extending only 1/4-1/5 distance to margin, never more than halfway to margin, a few sori near distal portion of pinnae bases arising at angles of 20-30°; indusia narrow.
||Latin contiguus, bordering, near, adjoining, probably referring to the sori that are contiguous and parallel to the midvein.
