Pterostylis bicornis
Horned greenhood is a small, deciduous terrestrial orchid from eastern Australia that grows from an underground tuber and flowers in winter. It is a wild native species that is rarely cultivated, and it needs cool, moist, shaded conditions in rock crevices.
Pterostylis bicornis, commonly known as horned greenhood, is a plant in the orchid family Orchidaceae and is endemic to eastern Australia. Non-flowering plants have a rosette of leaves while flowering plants have a similar rosette at the base of a flowering spike with a one or two dark green, white and brown flowers. The flowers have distinctive long, thin horn-like tips.
The horned greenhood grows in shallow soil pockets in rock crevices with moss and lichen. It is only known from Mount Maroon and the Mount Barney National Park in southern Queensland and from near Woodenbong in far northern New South Wales.
