Asplenium antiquum

Asplenium antiquum is a fern of the group known as bird's-nest ferns. In Japanese it is known by ō-tani-watari and tani-watari.[1]

Distribution[edit]

The fern is native to temperate East Asia, in China, Japan, Korea, and Taiwan on cliffs, dark forests, and tree trunks.[1][2] It is an IUCN endangered species in its native habitats.[1]

Description[edit]

Asplenium antiquum is an evergreen fern, 2–3 ft. (60–90 cm).[2] It has bright green, arching blades with a pointed end and a strong midrib.[2] Asplenium antiquum can readily be distinguished from the closely related Asplenium nidus by its fronds of uniform width.

Cultivation[edit]

The fern is commonly available in the plant nursery trade as an ornamental plant in subtropical climates, and a house plant in the United States and Europe in zones 9 and 10. It requires high humidity and bright indirect light, so does best in a greenhouse or terrarium if grown indoors.[2] It needs minimal watering and minimal soil (similar to an orchid).[2]

Chemical composition[edit]

Mearnsetin 3,7-dirhamnoside, a glycoside of the flavonol mearnsetin, can be found in A. antiquum.[3]
