Pterostylis venosa, commonly known as a greenhood, is a species of orchid endemic to New Zealand and which usually grows in colonies.

Pterostylis venosa is a terrestrial, perennial, deciduous, herb with an underground tuber and which usually grows in colonies of three or more plants.

The dorsal sepal and petals are fused, forming a hood or "galea" over the column.

[2][3] Pterostylis venosa was first formally described in 1895 by William Colenso from a specimen collected on the east side of the Ruahine Range.

[5] This greenhood mostly grows in montane ecosystems, usually in Nothofagus forest, often in deep leaf litter or moss beds.
