Caladenia remota subsp. remota, commonly known as the outback spider orchid, 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 one or two relatively large creamy-white to pale yellow flowers. It is relatively common in moist soil around granite outcrops, growing in more inland areas than most other spider orchids.

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 remota subsp. remota is a terrestrial, perennial, deciduous, herb with an underground tuber and a single erect, hairy leaf, 150–170 mm (6–7 in) long and about 5 mm (0.2 in) wide. One or two cream-coloured to creamy-yellow flowers 90–140 mm (4–6 in) long and 60–80 mm (2–3 in) wide are borne on a spike 150–250 mm (6–10 in) tall. The sepals and petals have long, brown, thread-like tips. The dorsal sepal is erect, 55–90 mm (2–4 in) long and 2–5 mm (0.08–0.2 in) wide. The lateral sepals are 55–90 mm (2–4 in) long and 4–5 mm (0.16–0.20 in) wide, spread apart and turned downwards. The petals are 55–80 mm (2–3 in) long and 2–3 mm (0.08–0.1 in) wide and spread horizontally near their bases but then turn downwards. The labellum is 13–18 mm (0.5–0.7 in) long, 11–12 mm (0.4–0.5 in) wide and cream coloured with red lines and marks. The sides of the labellum have many short blunt teeth, the tip curls under and there are two rows of anvil-shaped, white calli, sometimes with red tips, along its centre. Flowering occurs from August to mid December. [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 remota was first described in 2001 by Stephen Hopper and Andrew Phillip Brown and the description was published in Nuytsia . At the same time they described two subspecies, including subspecies remota. [1] The specific epithet (remota) is a Latin word meaning "distant" or "far off" [5] referring to the more inland distribution of this species of orchid. [3]

Stephen Donald Hopper AC FLS FTSE is a Western Australian botanist, graduated in Biology, specialising in conservation biology and vascular plants. He has written eight books, and has over 200 publications to his name. He was Director of Kings Park in Perth for seven years, and CEO of the Botanic Gardens and Parks Authority for five. 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.

Andrew Phillip Brown is a conservation biologist and taxonomist at the Western Australian Department of Environment and Conservation. He is also curator of Orchidaceae and Myoporaceae at the Western Australian Herbarium and a foundation member of the Australian Orchid Foundation and the Western Australia Native Orchid Study and Conservation Group. He is the author of more than 100 journal articles and seven books on the flora of Western Australia including a field guide to the eremophilas of that state.

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 outback spider orchid is found between Yalgoo and Bonnie Rock in the Avon Wheatbelt, Murchison and Yalgoo biogeographic regions where it usually grows in moist areas around the edges of granite outcrops. [2] [3] [4] [6]

Yalgoo, Western Australia Town in Western Australia

Yalgoo is a town in the Murchison region, 499 kilometres (310 mi) north-north-east of Perth and 118 kilometres (73 mi) east-north-east of Mullewa. Yalgoo is in the local government area of the Shire of Yalgoo.

Bonnie Rock, Western Australia Town in Western Australia

Bonnie Rock is a small town in the Wheatbelt region of Western Australia.

Avon Wheatbelt Bioregion

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

Conservation

Caladenia remota subsp. remota is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife. [6]

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.
