Caladenia lodgeana, commonly known as Lodge's spider orchid, is a species of orchid endemic to a restricted area of the south-west of Western Australia. It has a single, hairy leaf and up to three cream, red and pink flowers and a labellum which lacks the red tip common to many other similar caladenias.

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.

Labellum (botany)

In botany, the labellum is the part of the flower of an orchid or Canna, or other less-known genera that serves to attract insects, which pollinate the flower, and acts as a landing platform for them.

Description

Caladenia lodgeana is a terrestrial, perennial, deciduous, herb with an underground tuber and a single erect, hairy leaf, 100–200 mm (4–8 in) long and 5–15 mm (0.2–0.6 in) wide. Up to three cream-coloured, red and pink flowers 100–140 mm (4–6 in) long and 50–100 mm (2–4 in) wide are borne on a stalk 200–400 mm (8–20 in) tall. The sepals and petals have thin brown, club-like glandular tips 5–35 mm (0.2–1 in) long. The dorsal sepal is erect, 50–70 mm (2–3 in) long and 2–3 mm (0.08–0.1 in) wide. The lateral sepals are 55–75 mm (2–3 in) long, 4–6 mm (0.16–0.24 in) wide and spread widely. The petals are 35–65 mm (1–3 in) long and 2–4 mm (0.08–0.2 in) wide and spread widely. The labellum is 18–25 mm (0.7–1 in) long and 11–15 mm (0.4–0.6 in) wide and white or yellowish with the tip rolled under and lacking a red tip. The sides of the labellum have thin teeth up to 8 mm (0.3 in) long and there are four rows of pale red calli up to 1.5 mm (0.06 in) long in the centre. Flowering occurs from late October to early December. [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 lodgeana was first described in 2001 by Stephen Hopper and Andrew Phillip Brown from a specimen collected near Margaret River and the description was published in Nuytsia . [1] The specific epithet (lodgeana) honours the Western Australian orchid enthusiast Harry Lodge. [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.

Margaret River, Western Australia Town in Western Australia

Margaret River is a town in the South West of Western Australia, located in the valley of the eponymous Margaret River, 277 kilometres (172 mi) south of Perth, the state capital. Its Local Government Area is the Shire of Augusta-Margaret River.

Distribution and habitat

Lodge's spider orchid is only known from the area between Margaret River and Augusta in the Warren biogeographic region where it grows in seasonal swamps. [2] [3] [4] [5]

Augusta, Western Australia Town in Western Australia

Augusta is a town on the south-west coast of Western Australia, where the Blackwood River emerges into Flinders Bay. It is the nearest town to Cape Leeuwin, on the furthest southwest corner of the Australian continent. In the 2001 census it had a population of 1,091; by 2011 the population of the town was 1,292.

Warren (biogeographic region) biogeographic region in southern Western Australia

Warren, also known as Karri Forest Region and the Jarrah-Karri forest and shrublands ecoregion, is a biogeographic region in southern Western Australia. Located in the southwest corner of Western Australia between Cape Naturaliste and Albany, it is bordered to the north and east by the Jarrah Forest region. Its defining characteristic is an extensive tall forest of Eucalyptus diversicolor (karri). This occurs on dissected, hilly ground, with a moderately wet climate. Karri is a valuable timber and much of the karri forest has been logged over, but less than a third has been cleared for agriculture. Recognised as a region under the Interim Biogeographic Regionalisation for Australia (IBRA), and as a terrestrial ecoregion by the World Wide Fund for Nature, it was first defined by Ludwig Diels in 1906.

Conservation

Only about 137 mature plants from two populations of C. lodgeana were known in 2008. The species is classified as "Threatened Flora (Declared Rare Flora — Extant)" by the Western Australian Government Department of Parks and Wildlife [5] and is listed as "Critically Endangered" under the Australian Government Environment Protection and Biodiversity Conservation Act 1999 . The main threats to the species are inappropriate fire regimes, weed invasion, four-wheel driving, grazing, trampling, picking and continued drying of wetlands due to water extraction and land clearance. [6]

The Declared Rare and Priority Flora List is the system by which Western Australia's conservation flora are given a priority. Developed by the Government of Western Australia's Department of Environment and Conservation, it is used extensively within the department, including the Western Australian Herbarium. The herbarium's journal, Nuytsia, which has published over a quarter of the state's conservation taxa, requires a conservation status to be included in all publications of new Western Australian taxa that appear to be rare or endangered.
