Tree ferns are a tropical species, typically formed of a woody, trunklike stem crowned with a number of large, divided fronds. Elfin tree fern, Cyathea dryopteroides, is a small or dwarf tree fern reaching 24 in (61 cm) in height and approximately 1 in (2.5 cm) in diameter. The fronds are bipinnate, nearly hairless, tapered at both ends, and reach 36 in (91.4 cm) in length and 10 in (25.4 cm) in width. The sori are located dorsally and are enclosed in a cup-shaped indusium.Fertile fronds have frequently been observed on elfin tree fern at both known sites. The presence of healthy, vigorous plants in all stages of development suggests that successful reproduction and establishment occurs regularly.
