Caladenia multiclavia, commonly known as the lazy spider orchid is a species of orchid, endemic to the south-west of Western Australia. It has a single, hairy leaf and one or two greenish-yellow, red and cream-coloured flowers resembling a reclining spider. Although it usually only has a single flower, it often grows in clumps of up to six plants.

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 multiclavia is a terrestrial, perennial, deciduous, herb with an underground tuber and a single erect, hairy leaf, 40–100 mm (2–4 in) long and 5–10 mm (0.2–0.4 in) wide. Up to three greenish-yellow, red and cream-coloured flowers, 30–40 mm (1–2 in) long and wide are borne on a stalk 100–250 mm (4–10 in) tall. The flowers are greenish-yellow, red and cream-coloured, shaped like a reclining spider and the sepals and petals have thin, thread-like tips. The dorsal sepal and petals are close together and parallel, curved down behind the column near their bases, then upswept at the back of the flower. The lateral sepals are similarly arranged but at the front of the flower. The dorsal sepal is 30–40 mm (1–2 in) long and 3–4 mm (0.1–0.2 in) wide, the lateral sepals are 30–40 mm (1–2 in) long and 4–5 mm (0.16–0.20 in) wide and the petals are 25–35 mm (0.98–1.4 in) long and about 3 mm (0.12 in) wide. The labellum is 14–16 mm (0.55–0.63 in) long and wide, diamond-shaped and prominently red-striped in the centre of the flower. In the centre of the labellum there is a dense cluster of reddish, club-shaped calli up to 2.5 mm (0.1 in) long. Flowering occurs from 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 multiclavia was first described in 1871 by Heinrich Reichenbach and the description was published in Beitrage zur Systematischen Pflanzenkunde. [1] [5] The specific epithet (multiclavia) is derived from the Latin words multus meaning "much" or "many" [6] :64 and clava meaning "club", [6] :213 referring to the many calli on the labellum of this species. [3]

Heinrich Gustav Reichenbach German botanist

Heinrich Gustav Reichenbach was a botanist and the foremost German orchidologist of the 19th century. His father Heinrich Gottlieb Ludwig Reichenbach was also a well-known botanist.

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.

Latin Indo-European language of the Italic family

Latin is a classical language belonging to the Italic branch of the Indo-European languages. The Latin alphabet is derived from the Etruscan and Greek alphabets, and ultimately from the Phoenician alphabet.

Distribution and habitat

The lazy spider orchid occurs in a band between Wongan Hills and Ravensthorpe in the Avon Wheatbelt, Esperance Plains and Mallee biogeographic regions where it grows in she-oak thickets and open woodland. [2] [3] [4] [7]

Wongan Hills is a range of low flat-topped hills in the Avon Wheatbelt biogeographic region of Western Australia. It is located at 30°48′S116°37′E, in northern parts of the Avon Wheatbelt biogeographic region.

Ravensthorpe, Western Australia Town in Western Australia

Ravensthorpe is a town 541 km south-east of Perth, 40 km inland from the south coast of Western Australia. It is the seat of government of the Shire of Ravensthorpe. At the 2006 census, Ravensthorpe had a population of 438.

Avon Wheatbelt

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

Conservation

Caladenia multiclavia 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.
