Description
Rhizomes short-creeping, ca. 2 mm diam.; rhizome scales linear-lanceolate, ca. 2 mm long, castaneous to dark brown, lustrous, subentire with occasional teeth near scale bases; fronds approximate, 9–21 cm long; phyllopodia distinct; stipes 1⁄4–1⁄3 the sterile leaf length, stramineous to tan with scattered orange-tan, stellate hairs; blades linear, 5–20 cm X 4–7 mm, chartaceous, bases cuneate, apices acuminate; veins barely visible, ca. 1 mm apart, at 60–70° angle to costae; hydathodes absent; blade indument abaxially of sparse, stellate hairs, especially on the costae, those on the adaxial surfaces with narrow scale body; fertile fronds ca. equal to sterile fronds in length, narrower, and longer-stiped than the sterile, stipes 1⁄3–1⁄2 the frond length, blades 5–7 mm wide, stellate hairs on abaxial costae but not among the sporangia.A
