Cyathea holdridgeana, synonym Cyathea albomarginata, is a species of tree fern native to Panamá and Costa Rica.[1] It grows in wet forests at elevations of 2400–2800 m, considerably higher than most other tree ferns of Central America.
Cyathea holdridgeana is a small tree with a trunk up to 50 cm tall. Petiole purplish-brown with white margins, scaly but not spiny; scales (= modified appendages attached to the margins of the petioles) bicolored, dark purple in the center but white along the margins; dead scales appearing totally white. Leaves bipinnate; pinnulae 10–12 cm long[2][3][4][5]
