The genus was first scientifically described by
Lawrie A. S. Johnson in 1980.[1]
Many of the Gymnostoma species combinations of names (
binomials) were described by him in 1982.[3]
As of 2013[update], a global total of eighteen species have been found and described.[8][9]
The majority of the species grow in rainforests, in the habitats of open, sunny, long-term gaps, from
river bank (riparian) situations through to mountain top situations. In New Caledonia two endemic species G. chamaecyparis and G. deplancheanum have specialised adaptations, growing in wet "shrub
maquis and paraforest maquis formations. G. chamaecyparis is associated with
hypermagnesian soils (hypermagnesian
inceptisol) below 600 m altitude at the base of
ultramaficmassifs. G. deplancheanum occurs on
ferraliticferriticdesaturatedhardpan or gravelly soils (
oxisol) on the southern massif at altitudes between 200 and 1,000 m".[5]
