Pterostylis parviflora, commonly known as the tiny greenhood, is a species of orchid endemic to south-eastern Australia.

Pterostylis pedunculata, commonly known as the upright maroonhood, is a species of orchid endemic to south-eastern Australia. Flowering plants have a rosette of two to six stalked leaves and a single green flower which is white near its base and tinged with reddish brown to black and with a gap between the petals and lateral sepals.

It has a single fleshy, channelled leaf and up to six relatively large, bright-blue flowers with darker veins. The arms on the side of the column are twisted and yellow, but not toothed at the tip.
