Pterostylis scitula is a terrestrial,
perennial,
deciduous,
herb with an underground
tuber and when not flowering, a rosette of leaves in diameter. Flowering plants have a single green and white flower long and wide on a flowering stem high. There are between two and four stem leaves long and wide on the flowering stem. The
dorsal sepal and
petals are fused, forming a hood or "galea" over the
column. The
lateral sepals are held closely against the galea, fused at their bases and almost closing the front of the flower with erect tips long. The labellum is small, narrow and not visible from outside the flower. Flowering occurs from August to September. ==Taxonomy and naming==
