Tall Greenhood (Pterostylis longifolia)
“Pterostylis longifolia, commonly known as the common leafy greenhood or tall greenhood, is a plant in the orchid family Orchidaceae and is endemic to eastern Australia. Flowering plants have up to seven flowers, which are green, partly transparent and have a labellum which is pale green and hairy with a blackish central stripe. Non-flowering plants have a rosette of leaves, but flowering plants lack the rosette, instead having five to eight stem leaves. A similar species, Pterostylis melagramma, has paler green flowers which have a less hairy labellum.” – Wikipedia
