Nematoceras
Nematoceras is a genus of orchids, sometimes known as spider orchids, helmet orchids or spidery helmet-orchids, found mainly in New Zealand and its subantarctic islands, with two species on Australia's Macquarie Island. The genus was originally described in 1853 by Joseph Dalton Hooker who published his description in The botany of the Antarctic voyage of H.M. discovery ships Erebus and Terror. II. Flora Novae-Zelandiae. In 2002 David Jones, Mark Clements and Brian Molloy transferred some species of Corybas to Nematoceras but the move has not been accepted by the World Checklist of Selected Plant Families at Royal Botanic Gardens, Kew.Species
