Dwarf shell orchid

Pterostylis brevichila, commonly known as the dwarf shell orchid, is a species of orchid endemic to the south-west of Western Australia. As with similar greenhoods, the flowering plants differ from those which are not flowering. The non-flowering plants have a rosette of leaves flat on the ground but the flowering plants have a single flower with leaves on the flowering spike. In this species, the flower is small and white with brown stripes and is similar to P. aspera but smaller in stature.
