<p>Pterostylis curta, commonly known as the blunt greenhood, is a species of orchid found in south-eastern Australia, Lord Howe Island and New Caledonia. It has a rosette of leaves at its base and a single white and green, forward leaning flower with a brown tip and a twisted labellum. (Wikipedia).  (Note these flowers are small, only 3/4 to 1 3/8" [2 to 3.5 cm]).

Photographed in the Peter Black Conservatory Lath House, Victoria Esplanade, Palmerston North. Had to use a fast shutter speed and thus high ISO as the wind was blowing the orchid around. When photographing at the Conservatory, I always photograph the flowers in place without touching them in any way.
