Oceaniopteris gibba, the miniature tree fern (syn.

Blechnum gibbum),[1] is a tropical species of fern in the family Blechnaceae, native to New Caledonia and introduced in Fiji.

[2] It has received the Royal Horticultural Society's Award of Garden Merit.

With a vertical "trunk" (actually a rhizome), it has bright green fronds.

As it does not tolerate temperatures below 15 °C (59 °F), in temperate zones it must be cultivated under glass all year round.
