Psilotum nudum, growing
to around 30cm in height, is a fern plant inhabiting trunks, rocks,
or rarely ground floors. The plant bodies lack roots and leaves; the
whole being stems above the ground and rhizomes underground. The
stems halfway upward potions repeat bifurcation at times, facing
upwards, and those branches have ridges with sparse protuberances.
Spores come in sporangium ripening yellow. Underground stems have
some rhizoids instead of roots.
