Cyclosorus acuminatus (Houtt.) Nakai
Information
Thelypteridaceae
Plants (20-)40-60(-80) cm tall. Rhizomes long creeping, apices including stipe bases with brown lanceolate scales. Fronds distant; stipes (10-)20-30(-40) cm, stramineous to brown; laminae (10-)30-50(-60) × 10-25 cm, bases not narrowed or slightly so, apices caudate to acuminate; lateral pinnae (5-)10-20 pairs, shortly stalked; middle pinnae linear-lanceolate to lanceolate, (5-)8-15(-18) × (0.5-)0.8-1.5(-2) cm, bases truncate or shallowly cordate, lobed 1/2-2/3 toward costae, apices acuminate to acute; segments (10-)15-30 pairs, 2-5 × 2-4 mm, basal acroscopic one (sometimes also basiscopic one) longer, sharply pointed or acute at apex; veinlets 6-10 pairs, simple (sometimes forked on basal acroscopic segment), proximal pair anastomosing, next (0.5-)1-1.5 pairs running to sinus membrane. Laminae papery to subleathery, grayish green when dried, both surfaces with short acicular hairs along costae and veins, also with minute hairs throughout. Sori orbicular, submarginal; indusia shortly hairy or subglabrous. Sporangia bearing reddish orange glands on stalks. Spores dark brown, densely cristate.
Long creeping rhizomes, apices including stipe bases with brown lanceolate scales. Laminae papery to subleathery, both surfaces with short acicular hairs along costae and veins, also with minute hairs throughout.

Current: Widely distributed in tropical, subtropical and temperate regions of the world.
Grows in humid environments on forest edges or plains, semi-open places in thickets, grasslands, farmland margins, roadsides.
Dispersal by spore propagation. Sori orbicular, submarginal, inserted above the middle part of the lateral veins, and each node has 5 to 8 pairs of lobes. Sporangia bearing reddish orange glands on stalks. Spores dark brown, densely cristate, and persistent; indusia shortly hairy or subglabrous. Spores are dispersed from their parent colonies passively by airflow and raindrops.
