Pterostylis vernalis, commonly known as the spring tiny greenhood, is a species of orchid endemic to New South Wales. As with similar orchids, the flowering plants differ from those that are not currently flowering. Non-flowering plants have a rosette of leaves at the base. Flowering plants lack that rosette, but have one or two rosettes on lateral growths. The flowers are green, brown and white. This greenhood is only known from a small area near Nowra.
