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.

Bremer Bay, Western Australia Town in Western Australia

Bremer Bay is a coastal town situated on the south coast of Western Australia in the Great Southern region between Albany and Esperance, at the mouth of the Bremer River. Bremer Bay is 515 kilometres (320 mi) southeast of the state capital, Perth, and 180 kilometres (112 mi) east of Albany. In 2016 the townsite had a population of 231. Over the 2018 Christmas and New Year holiday period the town's population reached almost 6,500.

Description

Caladenia pectinata is a terrestrial, perennial, deciduous, herb with an underground tuber and a single erect, hairy leaf, 150–300 mm (6–10 in) long and 10–20 mm (0.4–0.8 in) wide. Up to three red, yellow and pale green flowers 60–100 mm (2–4 in) long and 60–70 mm (2–3 in) wide are borne on a stalk 350–700 mm (10–30 in) tall. The sepals have thick, brown, club-like glandular tips 10–35 mm (0.4–1 in) long. The dorsal sepal is erect, 40–70 mm (2–3 in) long and 2–5 mm (0.08–0.2 in) wide. The lateral sepals are 40–70 mm (2–3 in) long and 6–9 mm (0.2–0.4 in) wide and turn downwards. The petals are 35–45 mm (1–2 in) long, 3–4 mm (0.1–0.2 in) wide and are sometimes spreading otherwise turn upwards. The labellum is 18–25 mm (0.7–1 in) long, 12–18 mm (0.5–0.7 in) wide and creamy-yellow with a dark red, down-curved tip. The sides of the labellum have linear teeth up to 8 mm (0.3 in) long and there are four or six rows of dark red calli along its mid-line. Flowering is from late September 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

Caladenia pectinata was first formally described by Richard Rogers in 1920 and the description was published in Transactions and Proceedings of the Royal Society of South Australia . [1] [5] The specific epithet (pectinata) is a Latin word meaning "comb-like" [6] referring to the fringe on the sides of the labellum. [3]

Richard Sanders Rogers Australian doctor, botanist, orchidologist

Richard Sanders Rogers was a distinguished Australian medical doctor, and world authority on Australasian orchids. He described over 80 Australian orchid species, three from New Zealand and 30 from New Guinea as well as three new genera including one from New Zealand. He was a consulting physician at the Adelaide Hospital and a member of its board. He may have been the first to practise hypnotism during surgery, allowing him to remove a cyst from a woman's breast without anaesthetics "while she was still awake and talking to assistants and witnesses standing nearby."

The Royal Society of South Australia (RSSA) is a Learned Society whose interest is in Science, particularly, but not only, of South Australia. The major aim of the Society is the promotion and diffusion of scientific knowledge, particularly in relation to Natural Sciences.

Botanical nomenclature is the formal, scientific naming of plants. It is related to, but distinct from taxonomy. Plant taxonomy is concerned with grouping and classifying plants; botanical nomenclature then provides names for the results of this process. The starting point for modern botanical nomenclature is Linnaeus' Species Plantarum of 1753. Botanical nomenclature is governed by the International Code of Nomenclature for algae, fungi, and plants (ICN), which replaces the International Code of Botanical Nomenclature (ICBN). Fossil plants are also covered by the code of nomenclature.

Distribution and habitat

The king spider orchid is widespread between Cataby and Munglinup in the Avon Wheatbelt, Esperance Plains, Geraldton Sandplains, Jarrah Forest, Mallee, Swan Coastal Plain, and Warren biogeographic regions. It is most common between Bremer Bay and Rocky Gully. [2] [3] [4] [7]

Cataby, Western Australia Town in Western Australia

Cataby is a small settlement approximately 170 kilometres (110 mi) north of Perth, Western Australia on the Brand Highway. The area was apparently once called West Dandaragan, with the town of Dandaragan located 17 km to the east.

Munglinup, Western Australia Town in Western Australia

Munglinup is a small town located in the Goldfields-Esperance region of Western Australia.

Avon Wheatbelt

The Avon Wheatbelt is an Australian bioregion in Western Australia and part of the larger Southwest Australia savanna ecoregion.

Conservation

Caladenia pectinata is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife. [7]

Department of Parks and Wildlife (Western Australia) department of the Government of Western Australia

The Department of Parks and Wildlife (DPaW) was the department of the Government of Western Australia responsible for managing lands described in the Conservation and Land Management Act 1984 and implementing the state's conservation and environment legislation and regulations. The minister responsible for the department was the Minister for the Environment.
