Pterostylis (Greek, wing column; the column is broadly winged). Orchidaceae. Terrestrial herbs with small underground tubers: radical lvs. ovate; st.-lvs. developed and linear or lanceolate, or reduced to scarious sheathing scales: fls. usually green, often tinged red or brown, large and solitary or smaller and several in a raceme; dorsal sepal broad, erect, incurved and very concave; petals lanceolate-falcate, attached to the basal projection of the column; labellum on a short claw at the end of the basal projection of the column, movable; column with a pair of hatchet-shaped or quadrangular wings.—About 50 species, mostly Australian but a few in New Zeal, and New Caledonia and 1 in New Guinea. P. curta, R. Br. Lvs. in a radical rosette, usually on long petioles, ovate or broadly elliptical, 5-9-nerved: scapes 1-fld.; usually about 6 in. high; galea erect, acute; lip linear, obtuse, entire, rather longer than the column; wings of the column with the lower lobe long and obtuse, the upper lobe short and broad. Austral. B.M. 3086. O. 1910:104. Cult, to some extent in greenhouses abroad as are the following: P. acuminata, R. Br. Austral. B.M. 3401; P. Banksii, R. Br. New Zeal. B.M. 3172; P. Baptistii, Fitzg. Austral. B.M. 6351; and P. nutans, R. Br. Austral. B.M. 3085. They are prop, by division and thrive in lf .-mold lightened by a little sand; the lower third of the pots should be filled with broken crocks. F. Tracy Hubbard.

(4) - pollinia

Pterostylis is a terrestrial deciduous genus of some 100 or so species of orchids found mainly in New Zealand, Australia, Papua New Guinea and New Caledonia. The common name of this orchid is Greenhood - a number of species have green flowers with the dorsal sepal forming a "hood" over the rest of the flower. The name Pterostylis is based on the Greek words meaning winged column (pteron - a wing, stylis - a column). In a number of species, the flower has a hinged lip that swings backwards when touched by an insect, forming a tube with the column and wings. The trapped insect is then forced to crawl out of the tube, removing the pollinia in the process.
