Distribution en:

Description en: Genus of 20 epiphytic, evergreen ferns found in tropical forest and scrub in tropical Africa, S.E. Asia, and Australia, with thick, creeping rhizomes and 2 types of frond. Basal fronds are papery, oak-like in shape, stalkless, and sterile. They turn brown quickly and form a "nest" in which humus collects. The taller, stalked, more upright fertile fronds remain green. They are either deeply pinnate, with linear pinnae, or pinnatisect; small groups of spores form on the undersides. The pinnae are often shed in dry periods, leaving long, bare midribs. All fronds, even when fresh, have a thin, leathery texture. In frost-prone areas, grow in a warm greenhouse; elsewhere, grow epiphytically.

Hardiness en: Frost tender.

Cultivation en:

Propagation en: D. rigidula increases readily from spores, sown at 21°C (70°F) as soon as ripe; other species are less easy to propagate from spores. Divide the rhizomes of large specimens in spring, and make sure that each portion has at least one growing tip. See also p.51.

Pests en: Scale insects may infest fronds.
