#pseudodiphasium

AKA Pseudodiphasium volubile. 'volubile' mean 'twining'.

Another clubmoss at the Craters of the Moon, although this one was growing further away from the scorching subterranean heat and had small trees and shrubs to clamber over. Distinguished from other clubmosses by the flattened fronds, and drooping strobili (spore-bearing structures). Photos of them from another of my sightings.

Wikipedia says the species is found from Malaysia to Queensland, Australia, and has been introduced to Equador, but the New Zealand Plant Conservation Network says that it's native to many parts of Aotearoa, and that there's only a single record of the species in Australia.

Found in many habitats from coastal to montane, in gumland scrub, shrublands, forest margins and along open ridgelines in dense forest, and on roadsides and cuttings. Difficult to propagate in captivity, apparently.
