Cyrtostylis

Cyrtostylis is a genus of orchid. It contains 5 currently recognized species, native to Australia and New Zealand.^[1]

The genus was first described by Robert Brown in his Prodromus Florae Novae Hollandiae (1810). The type species for the genus is Cyrtostylis reniformis. It shares many morphological characteristics of another genus, Acianthus, and some author have merged the two genera into one.

Cyrtostylis oblonga Hook.f. - New Zealand
Cyrtostylis reniformis R.Br. - All 6 states of Australia
Cyrtostylis robusta D.L.Jones & M.A.Clem - South Australia, Western Australia, Tasmania, Victoria
Cyrtostylis rotundifolia Hook.f. - New Zealand
Cyrtostylis tenuissima (Nicholls & Goadby) D.L.Jones & M.A.Clem. - Western Australia
