Common Name: Summer Greenhood
Synonym: Diplodium decurvum
Family: Orchidaceae

Description: Perennial herb rising from round tubers to form sparse 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: Upright or ground-hugging rosette of 2-5 long-stalked dark green oblong leaves 20-30mm x 10-20mm, on non-flowering plants only. 4-5 lance-shaped stem leaves on flowering plants.
Flowering: Single flower to 25mm. Hood curved forward and downward from halfway, tips tinged brown, sepal tip finely pointed to 20mm long. Lateral sepals erect, gap wide, points erect to 4cm. Lip brown, curved, blunt tip visible.
Flower Colour: Pale to dark green and white
Flowering Time: October to March
Growing Conditions: Moist soil on slopes of mountain forests. Dappled to full 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.
