An elegant tree fern introduced from Queensland, by William Bull, of Chelsea, London. The stem is very slender; the the fronds are elliptic, bipinnate, the larger pinnae bearing on each side numerous pinnules, which are stalked, linear acuminate, with an unequal sub-cordate base and an inciso-crenate margin. The texture of the frond is firm, the surface glabrous; the rachis clothed on the upper surface with black fibrillose scales. It is very distinct from all other Australian tree ferns, and a very elegant addition to the group.

Alsophila Rebeccae.
