Taxonomy edit

This species has a complex taxonomic history and has been previously assigned to several genera.[1]

Description edit

The 5–10 cm, sometimes up to 20 cm long stems are 8–15 mm wide and enclosed within persistent leaf sheaths. They bear oblong to obovate-oblong, unequally bilobed, coriaceous leaves, between 17 and 29 cm in length and 3.5-5.5 cm in width. Yellow flowers of 4–5 cm in diameter with purple spotting and a white lip with lavender colouration on the midlobe are produced on 5-8 flowered, axillary and often pendent inflorescences. One plant may produce up to 6 inflorescences at a time. Flowering occurs throughout June and July. The diploid chromosome count is 2n = 38.[2] Each pollinium is completely divided into two unequal halves.[3] The seeds are 238.7 µm long and 81.2 µm wide.[4]
