Encyclopedia
Cyathea cucullifera is a species of tree fern
native to eastern New Guinea
, where it grows in montane forest at an altitude of about 2400 m. The trunk is erect and 2-3 m tall. Frond
s are bi- or tripinnate and 2-3 m long. Characteristically of this species, they occur in two whorls of four to six fronds each. The stipe
is warty and covered with scale
s. The scales are dark, glossy, have a narrow paler margin and are large towards the base. Sori
occur near the fertile pinnule midvein and are covered by thin, pale brown indusia that are scale-like in appearance.
