Pterostylis arenicola
Also called Sandhill Greenhood
A small terrestrial orchid from South Australia that grows from an underground tuber and flowers on a slender spike with up to ten brown and white flowers. It is a native wild orchid, best left in its sandy woodland habitat rather than grown in gardens.
Pterostylis arenicola, commonly known as sandhill rustyhood is a plant in the orchid family Orchidaceae and is endemic to South Australia. It has a rosette of leaves near its base and up to ten reddish-brown and white flowers with a dark brown, insect-like labellum. Its distribution is now restricted to areas around Lake Alexandrina.
Sandhill rustyhood is only known from populations at Grange in the Adelaide metropolitan area, Tailem Bend, Coorong National Park, Meningie and Narrung Peninsula. It is locally common in sandy soil on coloured sand dunes in mallee and Callitris woodland with an understorey of shrub, heath, sedge and grass.
