Cyrtostylis rotundifolia, commonly known as the winter orchid[1] or gnat orchid,[2] is a species of orchid endemic to New Zealand. It has a single egg-shaped leaf and a flowering stem with up to four pink or pinkish green flowers with a flat, oblong labellum. It is very similar to Cyrtostylis oblonga and more investigation is required to determine if they are distinct from each other.
Description
Cyrtostylis rotundifolia is a terrestrial, perennial, deciduous, herb with a single kidney-shaped, egg-shaped, heart-shaped or almost round leaf Шаблон:Convert long and Шаблон:Convert wide. Up to four pink or pinkish green flowers Шаблон:Convert long are borne on a thin flowering stem up to Шаблон:Convert high. The dorsal sepal is erect, linear to narrow lance-shaped and the lateral sepals are narrow linear and somewhat smaller than the dorsal sepal. The petals are similar in size and shape to the lateral sepals. The labellum is flat, oval, about Шаблон:Convert long Шаблон:Convert wide with two round calli at the base and two parallel longitudinal ridges. The column is shorter than the labellum and has two wings widening towards the tip. Flowering occurs from June to October.[1][2]
This species is very similar to C. oblonga and "the status of these two species requires further investigation". It has grey-green mostly egg-shaped leaves compared to the yellowish green, oblong leaves of C. oblonga.[1]
Taxonomy and naming
Cyrtostylis rotundifolia was first formally described in 1853 by Joseph Dalton Hooker and the description was published in Flora Novae-Zelandiae.[3][4] The specific epithet (rotundifolia) is derived from the Latin words rotundus meaning "round", "circular" or "spherical"[5]Шаблон:Rp and folium meaning "leaf".[5]Шаблон:Rp
Distribution and habitat
The winter orchid grows in lightly shaded scrub and open in areas on the northern half of the North Island and the lower two-thirds of the South Island of New Zealand.[1][2]
