It is usually found growing on rocks, mainly in the Sino-Himalayan region at altitudes from approximately 2,000 to 5,000 metres above sea level.

This species has an unusual behaviour for a fern - it sheds its leaves during winter leaving the rhizome alive (this is known as a sleeping rhizome).

Distribution and habitat

The distribution of this species is centred in the Sino-Himalayan region with extension towards north and central China and Taiwan.

The species is epiphytic and grows on rocks. It shows a preference for growing in alpine habitats - usually on the top of mountains at between 2,000m and 5,000m above sea level.

Conservation

This species is reported as an endangered species in Taiwan and Japan because there are only a few populations there. However, the species is widespread and locally common in the western Himalaya and Hengduan Mountains.
