Orchidaceae family of plants

The Orchidaceae are a diverse and widespread family of flowering plants, with blooms that are often colourful and fragrant, commonly known as the orchid family.

Endemism Ecological state of being unique to a defined geographic location or habitat

Endemism is the ecological state of a species being unique to a defined geographic location, such as an island, nation, country or other defined zone, or habitat type; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. The extreme opposite of endemism is cosmopolitan distribution. An alternative term for a species that is endemic is precinctive, which applies to species that are restricted to a defined geographical area.

New Zealand Country in Oceania

New Zealand is a sovereign island country in the southwestern Pacific Ocean. The country geographically comprises two main landmasses—the North Island, and the South Island —and around 600 smaller islands. It has a total land area of 268,000 square kilometres (103,500 sq mi). New Zealand is situated some 2,000 kilometres (1,200 mi) east of Australia across the Tasman Sea and roughly 1,000 kilometres (600 mi) south of the Pacific island areas of New Caledonia, Fiji, and Tonga. Because of its remoteness, it was one of the last lands to be settled by humans. During its long period of isolation, New Zealand developed a distinct biodiversity of animal, fungal, and plant life. The country's varied topography and its sharp mountain peaks, such as the Southern Alps, owe much to the tectonic uplift of land and volcanic eruptions. New Zealand's capital city is Wellington, while its most populous city is Auckland.

Description

Caladenia chlorostyla is a terrestrial, perennial, deciduous, herb, usually occurring as a solitary individual. It has an underground tuber and a single sparsely hairy, bright green, narrow linear leaf up to 5–15 cm (2–6 in) long and 1–3 mm (0.04–0.1 in) wide. [3]

Perennial plant Plant that lives for more than two years

A perennial plant or simply perennial is a plant that lives more than two years. Some sources cite perennial plants being plants that live more than three years. The term is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth from trees and shrubs, which are also technically perennials.

Deciduous Trees or shrubs that lose their leaves seasonally

In the fields of horticulture and botany, the term deciduous (/dɪˈsɪdʒuəs/) means "falling off at maturity" and "tending to fall off", in reference to trees and shrubs that seasonally shed leaves, usually in the autumn; to the shedding of petals, after flowering; and to the shedding of ripe fruit.

Herbaceous plant Plant which has no persistent woody stem above ground

Herbaceous plants in botany, frequently shortened to herbs, are vascular plants that have no persistent woody stems above ground. Herb has other meanings in cooking, medicine, and other fields. Herbaceous plants are those plants that do not have woody stems, they include many perennials, and nearly all annuals and biennials, they include both forbs and graminoids.

One, sometimes up to five, unscented flowers up to 11–16 mm (0.4–0.6 in) in diameter are borne on a thin, wiry spike, 1–30 cm (0.4–10 in) tall. The sepals and petals are white, pale mauve or pinkish with greenish-white tips. The dorsal sepal is erect with its sides turned forwards, the lateral sepals are held horizontally and flat and the petals either spread widely or turn inwards. The dorsal sepal is 6–11 mm (0.2–0.4 in) long and narrow egg-shaped, the lateral sepals and petals are 6–8 mm (0.2–0.3 in), about 2 mm (0.08 in) wide, curved like a sickle and egg-shaped with the narrower end towards the base. The column is green with transverse red bars. Flowering occurs between September and January and is followed from December to April by the fruit which is a green, oval-shaped capsule 10–12 mm (0.4–0.5 in) long which sometimes has purple stripes. [3]

Sepal part of a calyx

A sepal is a part of the flower of angiosperms. Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom. The term sepalum was coined by Noël Martin Joseph de Necker in 1790, and derived from the Greek σκέπη, a covering.

Petal Part of most types of flower

Petals are modified leaves that surround the reproductive parts of flowers. They are often brightly colored or unusually shaped to attract pollinators. Together, all of the petals of a flower are called a corolla. Petals are usually accompanied by another set of special leaves called sepals, that collectively form the calyx and lie just beneath the corolla. The calyx and the corolla together make up the perianth. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term tepal is appropriate include genera such as Aloe and Tulipa. Conversely, genera such as Rosa and Phaseolus have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly coloured tepals. Since they include Liliales, an alternative name is lilioid monocots.

Column (botany) reproductive structure that can be found in several plant families

The column, or technically the gynostemium, is a reproductive structure that can be found in several plant families: Aristolochiaceae, Orchidaceae, and Stylidiaceae.

Taxonomy and naming

Caladenia chlorostyla was first formally described in 1997 by David Jones, Brian Molloy and Mark Clements from a specimen collected by Clements near the Tinline River. The description was published in The Orchadian. [1]

Brian Peter John Molloy is a New Zealand plant ecologist, conservationist, and former rugby union player.

The Tinline River is a river of the Marlborough Region of New Zealand's South Island. It flows generally south from its sources at the northern end of the Bryant Range to reach the Pelorus River seven kilometres west of Pelorus Bridge.

Distribution and habitat

This caladenia grows in sunny position in scrub but also in old-growth forests and frequently in mature pine plantations. [3] [4]

Caladenia saccata is regarded as a synonym of C. chlorostyla in New Zealand. [2]

Conservation

Caladenia chlorostyla was classified in 2012 as "not threatened". [3]
