Common Name Melville's Habenaria

Flower Size

Found in Venezuela, Peru and Brazil on roadsides and in swamps always with a wet base at elevations of 1000 to 1200 meters as a large to giant sized, cool growing terrestrial with a claviform, obtuse, white wooly tuber giving rise to an erect, stout stem with 4 to 7, light green, deeply keeled, lanceolate leaves enveloping the stem that blooms in the early summer on a terminal, erect, 8 to 10" [20 to 25 cm] long, 1 to 15 flowered inflorescence.

This is the largest plant and flower of the Habenaria in the Rio de Janiero region.

CAUTION This group, H fastor, H nabucoi, H gourlieana and H macronectar are all fairly similar. I hope I have them separate in a correct fashion. H nabucoi is considered by Kew to be synomonous with this species but I have left them separate for now. H fastor is also considered by Kew to be synomonous with H melvillei.
