Its range is restricted to the Sandstone Mountains of the South Western Cape, South Africa, west of Hermanus to Table Mountain [4] and northwards into the Cederberg Mountains. [3] It is common on Table Mountain, and the Back Table, but is rarely seen further south on the Cape Peninsula. [1] The orchid grows near waterfalls, streamlets, and seeps in the mountains. [1] [3] It is, however, never found along the shores of dams whose water levels vary considerably during the year.

Description

It is a fairly stout perennial 15 – 60 cm in height, spreading by stolons. The leaves are lance shaped, the lower ones spreading or semi-erect up to 25 cm long. The inflorescence is 1-3 flowered. The blooms are showy, and can be 10 cm across the laterally spreading sepals, which are scarlet to carmine in color. The middle, upright sepal is pinkish on the inside with scarlet veins. [1] The petals, which are very much smaller than the sepals, are erect colored yellow with red spots at their tops, but pale scarlet at their bases. [1] It blooms during the summer months, particularly in January, but continuing into March. [1] [3] [2] [4] Its pollination is one of the most complex of all the orchids, involving the mountain pride butterfly, Aeropetes tulbaghia . [1]

As an emblem

The Mountain Club of South Africa, the Western Province Rugby Team and the Western Province sports use the image of this species on their badges and logos. It has been the Mountain Club's logo since its founding in 1891. The flowers are also depicted on the obverse side of the Pro Merito Medal (1975).

Table Mountain is a flat-topped mountain forming a prominent landmark overlooking the city of Cape Town in South Africa. It is a significant tourist attraction, with many visitors using the cableway or hiking to the top. Table Mountain National Park is the most visited national park in South Africa, attracting 4.2 million people every year for various activities. The mountain has 8,200 plant species, of which around 80% are fynbos, meaning fine bush. It forms part of the Table Mountain National Park, and part of the lands formerly ranged by Khoe-speaking clans, such as the !Uriǁʼaes. It is home to a large array of mostly endemic fauna and flora.

Fynbos is a small belt of natural shrubland or heathland vegetation located in the Western Cape and Eastern Cape provinces of South Africa. This area is predominantly coastal and mountainous, with a Mediterranean climate and rainy winters. The fynbos ecoregion is within the Mediterranean forests, woodlands, and scrub biome. In fields related to biogeography, fynbos is known for its exceptional degree of biodiversity and endemism, consisting of about 80% species of the Cape floral kingdom, where nearly 6,000 of them are endemic. This land continues to face severe human-caused threats, but due to the many economic uses of the fynbos, conservation efforts are being made to help restore it.

<i>Disa</i> (plant) Genus of flowering plants belonging to the orchid family

Disa is a genus of flowering plants in the family Orchidaceae. It comprises about 182 species. Most of the species are indigenous to tropical and southern Africa, with a few more in the Arabian Peninsula, Madagascar, and Réunion. Disa bracteata is naturalised in Western Australia, where the local name is "African weed-orchid."

<i>Caladenia</i> Genus of orchids

Caladenia, commonly known as spider orchids, is a genus of 350 species of plants in the orchid family, Orchidaceae. Spider orchids are terrestrial herbs with a single hairy leaf and a hairy stem. The labellum is fringed or toothed in most species and there are small projections called calli on the labellum. The flowers have adaptations to attract particular species of insects for pollination. The genus is divided into three groups on the basis of flower shape, broadly, spider orchids, zebra orchids and cowslip orchids, although other common names are often used. Although they occur in other countries, most are Australian and 136 species occur in Western Australia, making it the most species-rich orchid genus in that state.

<i>Prasophyllum</i> Genus of flowering plants

Prasophyllum, commonly known as leek orchids, is a genus of about 140 species of flowering plants in the orchid family, Orchidaceae and is found in Australia and New Zealand. The Australian species are found in all states but have not been recorded in the Northern Territory. The common name arises from their having a hollow, leek- or onion-like leaf. Some species only flower after summer fires and have flowers similar to those of Xanthorrhoea which flower at the same time, suggesting that they employ the same pollinating insects. Leek orchids are similar to those in the genus Genoplesium except that the free part of the leaf is cylindrical and the labellum has a solid connection to the column. They range in size from the little laughing leek orchid at about 15 cm (6 in) to the king leek orchid which grows up to 2 m (80 in) tall.

<i>Neotinea ustulata</i> Species of orchid

Neotinea ustulata, the burnt orchid or burnt-tip orchid, is a European terrestrial orchid native to mountains in central and southern Europe, growing at up to 2,400 m (7,900 ft) elevation. The plant is considered Endangered in Great Britain and Least Concern internationally based on IUCN Red List criteria. The burnt-tip orchid was voted the county flower of Wiltshire in 2002 following a poll by the wild flora conservation charity Plantlife.

The slender spur of the flower grades into the galea and measures 7 to 20 mm long. The lateral sepals project outward and are elliptic to narrowly elliptic, with apiculi that can reach up to 4 mm in length. The petals are spear-shaped and 5 to 7 mm long, while the lip is narrowly egg- to spear-shaped and 10 to 12 mm long.

Although the flowers have long, thread-like petals and sepals, they are shorter and darker than those of other spider orchids. It is a rare, relatively recently discovered species although often found near human activities.
