General Information
DistributionHawaiian Islands.
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.
