Caladenia hildae, commonly known as golden caps, [2] honey caladenia [3] or honey hood [4] is a plant in the orchid family Orchidaceae and is endemic to the south-east of mainland Australia. It is a ground orchid with a single leaf and up to four yellowish-brown to golden-brown flowers with darker tips on the sepals and petals.

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.

Australia Country in Oceania

Australia, officially the Commonwealth of Australia, is a sovereign country comprising the mainland of the Australian continent, the island of Tasmania and numerous smaller islands. It is the largest country in Oceania and the world's sixth-largest country by total area. The neighbouring countries are Papua New Guinea, Indonesia and East Timor to the north; the Solomon Islands and Vanuatu to the north-east; and New Zealand to the south-east. The population of 25 million is highly urbanised and heavily concentrated on the eastern seaboard. Australia's capital is Canberra, and its largest city is Sydney. The country's other major metropolitan areas are Melbourne, Brisbane, Perth and Adelaide.

Description

Caladenia hildae is a terrestrial, perennial, deciduous, herb with an underground tuber and a single, sparsely hairy, linear leaf, 70–200 mm (3–8 in) long and 1–3 mm (0.04–0.1 in) wide. There are up to four flowers on a spike 80–200 mm (3–8 in) tall. The flowers are yellowish-brown to golden-brown flowers with darker tips. The sepals and petals have pointed, drooping tips. The dorsal sepal is erect, 9–11 mm (0.35–0.43 in) long and about 3 mm (0.1 in) wide and curves forward forming a hood over and around the sides of the column. The lateral sepals and petals are 11–14 mm (0.4–0.6 in) long and about 3 mm (0.1 in) wide. The labellum is egg-shaped, 6–9 mm (0.2–0.4 in) long, 4–6 mm (0.16–0.24 in) wide with the sides turned up and the tip rolled under. The labellum is white with a dark purple, glandular tip, narrow white or yellow-tipped teeth on the sides and four crowded rows of calli along its mid-line. Flowering occurs in October and November.

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 hildae was first formally described in 1928 by Edward Pescott and William Nicholls and the description was published in The Victorian Naturalist. [1] [6] The specific epithet (hildae) honours Hilda Elliott for her assistance in obtaining grant money. [6] Although recognised by the Royal Botanic Gardens, Melbourne and the National Herbarium at the Royal Botanic Gardens, Sydney as a valid name, C. hildae is regarded as a synonym of Caladenia testacea var. hildae by the Royal Botanic Gardens, Kew. [7]

Edward Edgar Pescott was an Australian naturalist. He was Principal Governor of the Burnley School of Horticulture from 1909 to 1916, and Government Pomologist for the Victorian Department of Agriculture from 1917 to 1937. He was a Fellow of the Linnean Society of London

William Henry Nicholls was an Australian amateur botanist, authority on, and collector of Australian orchids. An accomplished photographer and watercolourist, he contributed almost 100 articles on orchids to The Victorian Naturalist, many of which described new species with line drawings. He was working on producing a 24-volume illustrated monograph of all the orchids of Australia when he died. Only four volumes were published shortly after his death but the entire work was published in a single book, Orchids of Australia in 1969. Some of the many orchids described and named by Nicholls and retaining the name he gave them include Caladenia caudata, Caladenia echidnachila, Caladenia ensata, Caladenia ferruginea, Caladenia magniclavata, Caladenia ornata, Caladenia praecox, Caladenia radiata, Pterostylis fischii, Pterostylis hamiltonii, Pterostylis hildae and Pterostylis tenuissima. The orchid Prasophyllum nichollsianum was named in his honour by Herman Rupp.

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

Golden caps grows in sparse or heathy forest and woodland in high-altitude areas in New South Wales south from the Kybean Range and in Victoria mainly eastwards from Omeo. [3] [2] [5]

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 2018, the population of New South Wales was over 7.9 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.

Victoria (Australia) State in Australia

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.

Omeo Town in Victoria, Australia

Omeo is a town in Victoria, Australia on the Great Alpine Road, east of Mount Hotham, in the Shire of East Gippsland. At the 2016 census, Omeo had a population of 406. The name is derived from the Aboriginal word for 'mountains' or 'hills'. Omeo is affectionately known as the City of the Alps with many historic buildings remaining in the town. The town is still the commercial hub for the Omeo Region and is a service centre for outlying communities such as Benambra, Cobungra, Cassilis, Swifts Creek, and Ensay.

Conservation

Caladenia hildae is listed as "rare" by the Victorian Government Department of Sustainability and Environment. [4]

Department of Sustainability and Environment

The Department of Sustainability and Environment (DSE) was a state government department that managed water resources, climate change, bushfires, public land, forests and eco systems in the state of Victoria, Australia. It was created in 2002 when the Department of Natural Resources and Environment was divided into the Department of Primary Industries and the Department of Sustainability and Environment.
