Pterostylis sp. aff. parviflora (Eastern Melbourne)

Common Name: Corranwarrabul Greenhood
Synonym: Separated from Pterostylis parviflora; Speculantha sp. aff. parviflora
Family: Orchidaceae
Size: 8-20cm high
Description: Perennial herb rising from round tubers to form loose colonies. Central sepal and petals united into a galea (hood) over the column and labellum (lip). Lateral sepals joined at the base, ending in fine points.
Leaves: Flowering plants - 1-3 ground-hugging rosettes form on side shoots from the stem. 3-10 stalked egg-shaped grey-green leaves to 20mm x 10mm, with wavy margins. 2-4 closely sheathing stem leaves on wiry stem. Sterile plants have a small rosette.
Flowering: 2-8 flowers to 12mm, facing into stem. Hood mostly erect, top curved forward, tip blunt. Lateral sepals brown with white stripes, erect, gap broad, protruding, points to 3mm. Lip just visible.
Flower Colour: White and green striped with green tinges, brown petals and lateral sepals
Flowering Time: March to May
Growing Conditions: Well drained soils in moist forest and heathy woodlands which are moist in the growing season. Semi shade.
Garden Use: Use of orchids in gardens is not recommended, unless they already occur naturally, in which case they need to be protected. Removing orchids from the bush usually results in their death and further depletes remaining wild orchid populations.
