(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.
