The Liawenee Greenhood is a terrestrial orchid growing to 15 cm tall, with small green and white striped flowers (TSU 2001c).
Pterostylis pratensis may be confused with P. cynocephala or P. ziegeleri (Jones et al. 1999).
This species is found at an altitude of 800-1100 m asl. It grows in subalpine Poa labillardierei tussock grassland which is often low and open with patches of stunted Olearia algida and Hakea microcarpa scrub on red-brown loamy-clay soils derived from basalt (TSU 2001c).
Flowering occurs from mid-Nov to mid-Dec (TSU 2001c).
The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
