Pterostylis curta, the blunt greenhood, is a terrestrial orchid mainly from Australia. This terrestrial orchid emerges from a dormant corm to produce a single, quite strange, green and windowed flower. The flower uses visual or olfactory trickery (like many orchids) to attract certain flies. It possesses a sensitive labellum which when triggered will pin the insect against the column of the flower for around a minute before releasing it. If all goes well, the insect will bear sticky pollinia away from the flower ensuring cross pollination when it visits another. Like many geophytes (plants with underground storage vessels), it can also multiply asexually and establish genetically identical communities. -- source link
