Plants bare and thread-like below, rather abruptly leafy above, dark green to chestnut-brown. Leaves with a narrower, lanceolate limb above the sheathing base, imbricate and crispate distally when dry, erect-spreading when moist, 7-8 mm, lamina 2-stratose, leaf tip truncate, with a single delicate, sinuous capillary hair (deciduous and often lost in older leaves); sheath pale to yellowish, not completely enclosing stem, oblong to subquadrate, entire, not hyaline-margined, with a wedge-shaped patch (hinge) of incrassate cells just above sheath; limb 0.7 mm wide at base, 4.5-5.5 mm; costa narrow, percurrent or excurrent with a few rows of teeth on abaxial surface near apex, forming discontinuous lamellae; lamina margins ± erect to broadly inflexed, entire below, 2-stratose and coarsely serrate in distal 1/3-1/2, teeth in pairs, terminal tooth cell not much larger than the others; lamina 2-stratose except for 1-2 rows of cells just inside the thickened margin, adaxial surface of lamina longitudinally grooved; lamina cells isodiametric, 7-12 µm wide, adaxial layer of cells in cross section higher than wide, turgid-mammillose, strongly bulging, moderately thick-walled; cells of abaxial layer isodiametric, ± plane, with thickened exterior walls; lamellae (18-)24-33 µm, restricted to 1/3-1/2 of leaf width, (5-)8-12(-15) cells high, in profile subentire to irregularly crenulate, marginal cells in cross-section undifferentiated or somewhat higher than wide and with a thickened apex, sporadically geminate. Sporophytes not reported within range of flora.
