These orchids are among the first greenhoods to flower each year, starting in May.
The Banded Greenhood is found from Perth to Albany and is distinguished by the long narrow lateral sepals and green colour.
The Dark Banded Greenhood is the most common of the banded greenhoods, being found throughout the wheatbelt and as far west as the Darling Range. It is distinguished by the flat more rounded lateral sepals and the darker colour of the flowers. The crowded variety is very similar and is distinguished by the way the flowers are crowded at the top of the stem. The variety has the same flower shape but is completely green in colour. The Cupped Banded Greenhood is also similar to the Dark Banded Greenhood but has much larger flowers and even more rounded lateral sepals with curved edges giving the cupped appearance.
