Macrothelypteris setigera (Blume) Ching

Plants 1-1.4 m tall. Rhizomes thick and ascending, with dense brownish linear-lanceolate scales; scales ca. 1 cm, thick, with sparse hairs along margins. Fronds clustered; stipes 50-60 cm or more, stramineous, bases with similar scales as rhizomes, distally sparse, scales inflated at bases and remaining as tuberculate rough marks after falling; laminae oblong-lanceolate, 50-80 × 30-50 cm, tapering at bases, 3-pinnate-pinnatifid, acuminate and pinnatifid at apices; pinnae 14-18 pairs, subopposite, spreading, sessile or subsessile, proximal pair larger, broadly lanceolate, 15-30 × 5-15 cm, bases truncate, symmetrical, bipinnate, apices acuminate; pinnules of 1-pinnate laminae 20-30 pairs or more, sessile, spreading, lanceolate, 2.5-7 × 0.5-1.5 cm, symmetrical at bases, pinnatisect, acuminate at apices; pinnules of bipinnate laminae 12-20 pairs, lanceolate, 2.5-7 × 1.5-2.5 mm, bases decurrent, connected to each other by narrow wings, entire or sharply lobate, margins usually recurved, obtuse at apices. Veinlets not evident, simple or forked, 3-5 per ultimate pinnule. Laminae herbaceous, brownish when dry, abaxially including costae and costules with more glaucous multicellular acicular hairs, adaxially with acicular hairs along costae, rachises with hard scales. Sori small, orbicular, attached above middle of veinlets, wrapped by recurved margins; indusia small, deciduous or hidden in mature sori.

In open places at medium altitudes; reported by Raciborski to form extensive thickets with Gleichenia hispida on G. Guntur in Java. Small plants may be fertile; one such was type of Cheilanthes stenophylla Kunze.
