Caladenia vulgata, commonly known as the common spider orchid, is a species of orchid endemic to the south-west of Western Australia. It is a relatively common and widespread orchid with a single erect, hairy leaf and up to three creamy-white flowers. There is some variation in the species, both in flower colour and growth habit.

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 vulgata is a terrestrial, perennial, deciduous, herb with an underground tuber and a single erect, hairy leaf, 50–150 mm long and about 4 mm wide. Up to three white or creamy-white flowers, sometimes with reddish markings, and 100–150 mm long, 70–100 mm wide are borne on a stalk 150–300 mm high. The dorsal sepal is erect, 45–90 mm long and 2–3 mm wide. The lateral sepals and petals are 45–90 mm long, 2–4 mm wide and horizontal near their bases, then curve downwards. The labellum is 9–15 mm long, 7–11 mm wide and cream coloured with red lines. The sides of the labellum have short, blunt teeth, the tip curls under and there are two rows of anvil-shaped, mostly cream-coloured calli along the mid-line. Flowering occurs from July to mid-October. The colour of the flowers of this orchid vary from glistening white to dull white or pale creamy white and in some areas the plants grow in large clumps and in others whereas in others they are solitary.

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 vulgata was first formally described in 2001 by Stephen Hopper and Andrew Phillip Brown from a specimen collected in the Kalbarri National Park and the description was published in Nuytsia . [1] The specific epithet (vulgata) is derived from the Latin word vulgaris meaning "common" [6] referring to the abundance of this species. [3]
