Caladenia callitrophila, commonly known as the Berrigan spider orchid is a plant in the orchid family Orchidaceae and is endemic to a small area in New South Wales. It has a single leaf and one or two pale greenish-yellow flowers with red markings and only occurs in three small populations.

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.

New South Wales State of Australia

New South Wales is a state on the east coast of Australia. It borders Queensland to the north, Victoria to the south, and South Australia to the west. Its coast borders the Tasman Sea to the east. The Australian Capital Territory is an enclave within the state. New South Wales' state capital is Sydney, which is also Australia's most populous city. In March 2019, the population of New South Wales was over 8 million, making it Australia's most populous state. Just under two-thirds of the state's population, 5.1 million, live in the Greater Sydney area. Inhabitants of New South Wales are referred to as New South Welshmen.

Description

Caladenia callitrophila is a terrestrial, perennial, deciduous, herb with an underground tuber and a single leaf, 70–130 mm (3–5 in) long and 4–12 mm (0.2–0.5 in) wide. One or two flowers are borne on a stalk 200–350 mm (8–10 in) tall. The flowers are pale greenish-yellow with reddish marks and are 50–60 mm (2.0–2.4 in) wide. The dorsal sepal is erect, 25–40 mm (1–2 in) long and about 2 mm (0.08 in) wide while the lateral sepals are about the same length but twice as wide, spread widely and turn down below horizontal. The petals are 20–30 mm (0.8–1 in) long and about 2 mm (0.08 in) wide and also deflected downwards at an angle. The labellum is 12–15 mm (0.5–0.6 in) long and 7–9 mm (0.3–0.4 in) wide, yellowish with red lines and a maroon tip. The labellum curves forward and downwards and there are six to nine pairs of red teeth on its sides. The mid-line of the labellum has four or six rows of maroon calli up to 1 mm (0.04 in) long. Flowering occurs from September to October. [2]

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 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 in botany, frequently shortened to herbs, are vascular plants that have no persistent woody stems above ground. Herb has other meanings in cooking, medicine, and other fields. Herbaceous plants are those plants that do not have woody stems, they include many perennials, and nearly all annuals and biennials, they include both forbs and graminoids.

Taxonomy and naming

Caladenia callitrophila was first formally described by David L. Jones in 1999 and the description was published in The Orchadian from a specimen collected near Berrigan. [1] The specific epithet (callitrophila) is derived from the name of cypress pines in the genus Callitris . This orchid grows in Callitris woodland. [2]

David Lloyd Jones is an Australian horticultural botanist and the author of many books and papers, especially on Australian orchids.

Berrigan, New South Wales Town in New South Wales, Australia

Berrigan is a town on the Riverina Highway in the Riverina region of New South Wales, Australia. Berrigan is in the Berrigan Shire local government area and contains the Berrigan Shire Council offices. At the 2016 census, Berrigan had a population of 1,260.

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.

Distribution and habitat

Berrigan orchid occurs in three small scattered populations near Berrigan where it grows in Callistris woodland. [2]
