Caladenia voigtii, commonly known as the mohawk orchid, is a species of orchid endemic to the south-west of Western Australia. It has a single erect, hairy leaf and usually only one greenish-yellow and red flower. When discovered near Salmon Gums in 1977, it was thought to be the extinct Caladenia cristata , but when C. cristata was found near Miling, the Salmon Gums discovery was renamed C. voigtii.

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.

Western Australia state in Australia

Western Australia is a state occupying the entire western third of Australia. It is bounded by the Indian Ocean to the north and west, and the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a total land area of 2,529,875 square kilometres, and the second-largest country subdivision in the world, surpassed only by Russia's Sakha Republic. The state has about 2.6 million inhabitants – around 11 percent of the national total – of whom the vast majority live in the south-west corner, 79 per cent of the population living in the Perth area, leaving the remainder of the state sparsely populated.

Salmon Gums, Western Australia Town in Western Australia

Salmon Gums is a small town in Western Australia located 106 km north of Esperance on the Coolgardie-Esperance Highway. The name is derived from a prominent stretch of Eucalyptus salmonophloia trees which formed a landmark in the town's early days. The town is part of the Shire of Esperance. At the 2006 census, Salmon Gums had a population of 789.

Description

Caladenia voigtii is a terrestrial, perennial, deciduous, herb with an underground tuber and a single erect leaf, 50–150 mm long and about 6 mm wide. Usually only one greenish-yellow flower with dark reddish markings and 20–30 mm long, 10–20 mm wide is borne on a stalk 80–200 mm high. The dorsal sepal is erect, 14–18 mm long and 2–3 mm wide. The lateral sepals are 14–18 mm wide, 3–4 mm long and turn stiffly downwards. The petals are 10–15 mm long, about 2 mm wide and spread horizontally or somewhat downwards. The labellum is 10–12 mm long, 8–12 mm wide, greenish with faint red lines and heart-shaped with a small, dark red, down-curved tip. There is a dense band of tall, red-tipped calli along the mid-line of the labellum. Flowering occurs from August to October. [2] [3] [4]

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. 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 are plants that have no persistent woody stem above ground. The term is mainly applied to perennials, but in botany it may also refer to annuals or biennials, and include both forbs and graminoids.

Taxonomy and naming

When discovered near Salmon Gums in 1977, it was thought to be Caladenia cristata which had been considered extinct since 1923, however when C. cristata was located near Miling, the present orchid was recognised as a new species. It was first formally described in 2001 by Stephen Hopper and Andrew Phillip Brown from the Salmon Gums specimen and the description was published in Nuytsia . [1] The specific epithet (voigtii) honours Don Voigt who found the first specimen. [3]

Nuytsia is a peer-reviewed scientific journal published by the Western Australian Herbarium. It publishes papers on systematic botany, giving preference to papers related to the flora of Western Australia. Nearly twenty percent of Western Australia's plant taxa have been published in Nuytsia. The journal was established in 1970 and has appeared irregularly since. The editor-in-chief is Kevin Thiele.

Distribution and habitat

The mohawk spider orchid is found between Bremer Bay and Balladonia in the Coolgardie and Mallee biogeographic regions where it grows in a variety of habitats including on granite outcrops and near salt lakes. [2] [3] [4] [5] [6]
