Davallia

Davallia is a genus of ferns, commonly known as hare's-foot ferns (though this name may also apply to other genera). They are native to tropical and subtropical regions around the world, including Asia, Australia, Africa, and the Pacific Islands.

Davallias are epiphytic or lithophytic, meaning they grow on other plants or rocks rather than in soil. A defining characteristic is their creeping rhizomes, which are often hairy and grow over the surface of their support. These rhizomes resemble animal feet or fur, giving rise to the common name "hare's-foot ferns."

The fronds of Davallia species are typically finely divided and delicate in appearance. They vary in size depending on the species, ranging from a few inches to several feet in length. The sori (spore-bearing structures) are located on the margins of the fronds, often protected by indusia.

Davallia ferns are popular as ornamental plants, particularly in hanging baskets and mounted on plaques, due to their attractive foliage and unique rhizomes. They thrive in humid environments with bright, indirect light. Several cultivars have been developed for horticultural purposes.

Some notable species within the Davallia genus include Davallia fejeensis (Rabbit's Foot Fern), Davallia trichomanoides (Black Rabbit's Foot Fern), and Davallia canariensis. The classification of species within the Davallia genus has been subject to revision over time.
