Caladenia reptans subsp. reptans, commonly known as the little pink fairy or dwarf pink fairy, is a plant in the orchid family Orchidaceae and is endemic to the south-west of Western Australia. It has a single hairy leaf and up to three relatively small, pink flowers which have a labellum with three distinct lobes.

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.

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.

Description

Caladenia reptans subsp. reptans is a terrestrial, perennial, deciduous, herb with an underground tuber and which often grows in clumps. It has a single, hairy leaf, 40–80 mm (2–3 in) long and about 8 mm (0.3 in) wide with a purplish lower surface. Up to three pale to dark pink flowers 10–20 mm (0.4–0.8 in) long and wide are borne on a spike 50–150 mm (2–6 in) tall. The dorsal sepal is erect, 10–15 mm (0.4–0.6 in) long and 4–6 mm (0.16–0.24 in) wide and the lateral sepals are a similar size. The petals are 9–14 mm (0.4–0.6 in) long and 3–4 mm (0.1–0.2 in) wide and spread fan-like with the lateral sepals. The labellum is 6–7 mm (0.2–0.3 in) long, 7–8 mm (0.28–0.31 in) wide and has three distinct lobes. The lateral lobes usually have three red stripes and the middle lobe has between four and ten short teeth on the sides. There are two rows of thick calli along the centre of the labellum. Flowering occurs from July to early October. In areas of high rainfall it tends to only flower after fire but in drier areas it flowers in the absence of summer fires. [2] [3] [4]

Terrestrial plant

A terrestrial plant is a plant that grows on, in, or from land. Other types of plants are aquatic, epiphytic and lithophytic.

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.

Taxonomy and naming

Caladenia reptans was first described in 1840 by John Lindley and the description was published in A Sketch of the Vegetation of the Swan River Colony . [5] [6] In 2001, Stephen Hopper and Andrew Phillip Brown described two subspecies, including subspecies reptans and the description was published in Nuytsia . [1] The specific epithet (reptans) is a Latin word meaning "creeping" [7] referring to the clumping habit of this orchid. [3]

He is currently Foundation Professor of Plant Conservation Biology at The University of Western Australia. He was Director of the Royal Botanic Gardens, Kew from 2006 to 2012.

Distribution and habitat

The little pink fairy is found between Kalbarri and Esperance in the Avon Wheatbelt, Esperance Plains, Jarrah Forest, Mallee, Swan Coastal Plain and Warren biogeographic regions where it grows in jarrah and wandoo woodland and in scrubland. [2] [3] [4] [8]
