Crepidomanes venosum, the veined bristle-fern or bristle filmy fern, is a fern in the family Hymenophyllaceae.
 It is only found in wet forests, mainly growing as an epiphyte on the shady side of the soft tree fern, "Dicksonia antartica".
 It also grows on logs, trunks of trees and rarely on trunks of "Cyathea" species or on wet rock-faces.
 It is found in the wetter parts of Eastern Australia and New Zealand.
 C. venosum has poor long-distance dispersal compared to other ferns due to its short lived spore.
 Notable features of "Crepidomanes venosum" include it being one cell layer thick, 5–15 cm in length, having many branching veins and a trumpet shaped indusium.
Hardenbergia is a small genus of leguminous vines from Australia.
Dicksonia youngiae, common name bristly tree fern, is a fern that comes from cool, sheltered rainforests in New South Wales and Queensland, Australia.
 It is found north of the Bellinger River, in New South Wales, and can be seen in the wild at Nightcap National Park.
Dicksonia is a genus of tree ferns in the order Cyatheales.
 It is regarded as related to "Cyathea", but is considered more primitive, dating back at least to the Jurassic and Cretaceous periods.
 The fossil record includes stems, pinnules, and spores.
