Jonesiopsis is a genus in the Orchidaceae family named in 2001 by Dariusz Szlachetko. After that date it was considered to be one of six genera in the splitting of Caladenia by some authors, considered a subgenus by others, and not recognized as a genus by others. As described species were terrestrial plants growing from tubers and with a hairy basal leaf. Flowers in this group were spidery with sepals and lateral petals narrowly elongated (filiform). You sometimes see species in this group referred to by a common name of Daddy Long Legs. Further taxonomic work by MA Clements, CG Howard CG1, and JT Miller published in 2015 did not support recognition of Jonesiopsis as a genus. For historical purposes and to avoid confusion we are keeping this page, but adding information and photos of species to the Caladenia wiki page.
The Australian terrestrial orchids are notoriously challenging to grow, although some enthusiasts are starting to achieve success by cultivating the symbiotic fungus that many of the orchids require in order to grow. Very careful fertilization is required to keep the fungus and orchid in balance. There's a good discussion of the relationship by clicking on mycorrhiza here.
