Pterostylis hildae

Pterostylis hildae is a terrestrial, perennial, deciduous, herb with an underground tuber and a rosette of between two and four elliptic leaves, each leaf long and wide. The leaves have a distinct petiole and sometimes a wavy edge. When flowering, there is a single green, white and brown flower long and wide which is borne on a flowering spike high. The dorsal sepal and petals are fused to form a hood or "galea" over the column and the petals and dorsal sepal have a short point on their tips which end at or near horizontal. There is a wide gap at each side of the flower between the petals and lateral sepals. The lateral sepals are erect with a tapering tip long no higher than the galea and there is a curved sinus with a deep notch between them. The labellum is long, about wide, curved and projects through the sinus. Flowering occurs from March to October. ==Taxonomy and naming==

Pterostylis hildae was first described in 1937 by William Nicholls and the description was published in The Victorian Naturalist from a specimen collected on Tamborine Mountain. The specific epithet (hildae) honours Hilda Geissmann for her contributions to nature study in Queensland. ==Distribution and habitat==

Rainforest greenhood is widespread and common in wet forest and rainforest between the Atherton Tableland in Queensland and Wollongong in New South Wales. ==References==
