| Pterostylis
(greenhoods) is one of the largest of Tasmania's genera of
orchids, with 36 species currently recognised.
The plant has several narrow leaves growing from an erect
stem that bears several to many, widely spaced flowers.
The flowers are unmistakeable - the dorsal sepal and
lateral petals are fused together to form a large hood
over the other flower parts. The hood is often green or
green with white stripes, and is often somewhat
translucent.
