Caladenia flavovirens, commonly known as the summer spider orchid, [2] or the Christmas spider orchid [3] is a plant in the orchid family Orchidaceae and is endemic to Victoria in Australia. It is a ground orchid with a single hairy leaf and one or two pale greenish-yellow flowers.
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 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.
Victoria is a state in south-eastern Australia. Victoria is Australia's smallest mainland state and its second-most populous state overall, thus making it the most densely populated state overall. Most of its population lives concentrated in the area surrounding Port Phillip Bay, which includes the metropolitan area of its state capital and largest city, Melbourne, Australia's second-largest city. Victoria is bordered by Bass Strait and Tasmania to the south, New South Wales to the north, the Tasman Sea to the east, and South Australia to the west.
Caladenia flavovirens is a terrestrial, perennial, deciduous, herb with an underground tuber and a single hairy, narrow lance-shaped leaf, 150–300 mm (6–10 in) long and 8–20 mm (0.3–0.8 in) wide. One or two pale greenish-yellow flowers are borne on a spike 300–600 mm (10–20 in) high. The sepals and petals taper to brownish, thread-like tips. The dorsal sepal is erect, 90–130 mm (4–5 in) long, about 4 mm (0.2 in) wide and the lateral sepals are 100–150 mm (4–6 in) long and 7–10 mm (0.3–0.4 in) wide. The petals are 75–95 mm (3–4 in) long, about 6 mm (0.2 in) wide. The labellum is egg-shaped, 15–23 mm (0.6–0.9 in) long and 10–12 mm (0.4–0.5 in) wide with its edges turned up. It is yellowish green with its maroon-coloured tip rolled under. There are many narrow thin teeth along the edges and four or six rows of red or yellow calli along its centre line. Flowering occurs from December to January. [2] [3] [4] [5]
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.
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 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.
Caladenia flavovirens was first formally described by Geoffrey Carr in 1991 from a specimen collected near Montrose. The description was published in Indigenous Flora and Fauna Association Miscellaneous Paper 1. [1] The specific epithet (flavovirens) is from the Latin words flavus meaning “golden-yellow” or "yellow" [6] :872 and virens meaning "green". [6] :383
Montrose is a suburb in Melbourne, Victoria, Australia, 33 km east of Melbourne's central business district. Its local government area is the Shire of Yarra Ranges. At the 2011 census, Montrose had a population of 6,732. Montrose varies in altitude, from about 91m to 324m above sea level. Montrose covers an area of about 1084 hectares or around 11 square kilometres (km2)
A botanical name is a formal scientific name conforming to the International Code of Nomenclature for algae, fungi, and plants (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the International Code of Nomenclature for Cultivated Plants (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae (Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups ."
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.
Summer spider orchid grows among shrubs in near-coastal areas and in open forest with grass or heath on mountains. It is only found in Victoria where it was once common but now rare and possibly extinct in areas near Portland, Lorne and Marlo. [2] [3]
Portland is a small city in Victoria, Australia, and is the oldest European settlement in the state. It is also the main urban centre in the Shire of Glenelg and is located on Portland Bay.
Lorne is a seaside town on Louttit Bay in Victoria, Australia. It is situated about the Erskine River and is a popular destination on the Great Ocean Road tourist route. Lorne is in the Surf Coast Shire and at the 2016 census had a population of 1,114 but this figure grows during the holiday season.
Marlo is a small village in the Gippsland region of Victoria, Australia. It is located east near the mouth of the Snowy River where the Snowy River meets and flows into the Southern Ocean. The name "Marlo" is generally accepted to have roots in tribal aboriginal language. "Marloo" meaning white clay is suggestive of the Marlo Bluff, whilst "Murloo" meaning "muddy banks" was reportedly used by the local indigenous people. At the 2006 census, Marlo had a population of 340.
Caladenia flavovirens is listed as "rare" in the Department of Environment and Primary Industries Advisory List of Rare Or Threatened Plants In Victoria. [7]
