Description
Phaius bernaysii is a ground orchid growing up to 2m tall when in flower and forming clumps up to 1m wide. The stems have a bulb-like enlargement and are crowded, 50-70 by 50-70mm. There are 4-7 leaves that are dark green and pleated, 50-125cm long by 8-10cm wide.
The flower spikes are 2m tall, stout and contain 4-16 flowers. The flowers are fleshy, measuring 6-10cm by 6.5-11cm, white on the outside and pale yellow-green to yellow on the inside. The central column-like petal (labellum) is yellow to white in colour. The lateral lobes of the labellum are usually incurved beside the column and sometimes extend above the column, but do not form a tight tube.
P. bernaysii differs from P. australis in the flower colour and is indistinguishable when not in flower. (DEWHA 2008)
