An evergreen terrestrial orchid forming tall clumps. Crowded pseudobulbs 4–6 cm long each with three or four pleated leaves (the epithet means pleated) 50–90 cm long and 1–1.5 cm wide. A hairy flowering stem 50–100 cm tall with up to forty deep pink to purple flowers 3.5–5.5 cm across; the lip T-shaped and three-lobed, the side lobes near vertical, with a yellow callus at the centre. The type species of its genus.
Habitat
Sunny grassy slopes, roadsides, forest edge and wetland margins, and widely planted in tropical parks, roadside beds and borders, one of the easiest terrestrial orchids to grow.
Distribution
Tropical and subtropical Asia to Australia (Cape York in Queensland) and the western Pacific (Tonga, Samoa); very common in Singapore's parks and roadsides, wild on Taiwan's Orchid and Green Islands, scarce in Hainan, present in the Ryukyus.
Season and behaviour
Flowers all year in Singapore, most after the rains; a stem opens in succession and lasts weeks.
Photography tips
These are the FilmAnalysis editors' notes, not content from the sources.
Purple goes blue in tropical sun and is true only in soft light or half shade; the yellow callus in the lip's centre is the macro focus, from the front and slightly above. The pleated leaves show their ribs against the light and make a background. Tall stems sway in wind, so 1/500 s or faster.
