Pterostylis

Pterostylis is a genus of orchids commonly found in Australia and New Zealand. They are terrestrial plants, typically growing from 10 to 40 centimeters tall, with a pseudobulb-bearing rhizome. The name Pterostylis comes from the Greek words pteron, meaning "wing", and stils, meaning "style", likely due to the club-shaped capsule of the flowers.

Pterostylis species are known for their varying flower shapes and colors, often with a six-lobed or three-lobed lip. The flowers typically range in color from green, yellow, or brown to purple and pink. The lip of the flower, which varies in shape and length, serves as the primary attractor for pollinators.

Pterostylis species often do not have noticeable foliage, with the leaves reduced or flattened. This adaptation is likely linked to the plants' relation to their specific environments and habitats. In the wild, they typically prefer shaded, moist environments, often near native vegetation.

Pterostylis is a widespread genus, with species found across eastern and southern regions of Australia and New Zealand. Many species have specialized usage in the horticulture industry, likely due to their unique flower patterns and varying colors.

The conservation status of many Pterostylis species remains as threatened or vulnerable due to habitat loss and degradation. Efforts to protect native habitats and establish conservation programs are required to ensure the survival of these species.
