Cephalanthera erecta var. subaphylla
is a perennial orchid species in hilly
district forests. Its stems grow to 10-15cm in height during
flowering, with the leaves retrogressing as if to change into
sheaths. The highest-positioned ones, 1-2cm in length, look close to
standard, though. Shoot tops set 2-3, about 1cm long, with half-open
white flowers. There is one or two bracts at the base of the
peduncles. The lip's central lobes are equipped with three
yellow-brown ridges. Bloom time: May-June. |
