This semi-evergreen fern grows to 1 m (3.3 ft) tall and broad, with narrowly divided fronds growing in a vase-like shape from a central crown, which is brown in colour.[1]
It has gained the Royal Horticultural Society's Award of Garden Merit.[1]
The acylphloroglucinols (flavaspidic acids[2]) isolated from D. crassirhizoma show in vitro antibacterial and fatty acid synthase inhibitory activity.[3] Also, the constituents sutchuenoside A and kaempferitrin have in vivo antiparasitic activity.[4]
