Description

Rhizome long creeping, 4–5(–10) mm diam., dark brown, densely scaly; scales pseudopeltate, clathrate, ovate with tails, 1.8–5 mm long including tails, 0.8–2 mm broad at base, brown, entire to short-dentate. Stipes stramineous or brownish in upper parts, 20–35 cm long, minutely scaly or glabrescent. Laminae pinnate with distinct terminal pinnae, oblong to lanceolate, 35–60(–150) by 14–44 cm; lateral pinnae up to 20 pairs, ascending, more or less falcate, lower to middle ones larger, distinctly stalked, linear-lanceolate, cuneate at base, caudately acuminate at apex, 7–22 by 2–2.5 cm, serrate at margin, upper pinnae gradually becoming smaller upwards; terminal pinna up to 15 cm long; veins anastomosing to form 2–4 rows of areoles at each side of costa; herbaceous, green, glabrous or with minute 2-celled glandular hairs. Sori round to elliptic, terminal on simple included veinlets in costal areoles, in a single row at each side of costa, medial or costular, up to 2 mm diam., distinctly immersed .

Distribution in Thailand

SOUTH-EASTERN: Chanthaburi; PENINSULAR: Nakhon Si Thammarat, Trang, Yala.

Wider Distribution

Himalayas to the Pacific.

Ecology

On mossy tree trunks in light shade or in dense evergreen forests, not so common at 400–1500 m alt.

Proposed IUCN Conservation Assessment

Least Concern (LC). This species is widespread and not under any known threat.

Notes

Tagawa & Iwatsuki (1989) and Holttum (1955) both report that the rhizome in this species is glaucous but all of the Thai material we have seen has a brown rhizome .
