RARE ORCHID 

Paphiopedilum rothschildianum

Paphiopedilum rothschildianum, commonly known as the Gold of Kinabalu orchid or Rothschild's slipper orchid, is a large sized clear-leafed species of orchid. It blooms with a tall inflorescence with up to six, large flowers. It is unique in the Corypetalum group by holding its petals almost horizontally, giving the flower a very distinctive appearance. The peak flowering period is from April to May.

Shenzhen Nongke Orchid

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.

Along with the Asteraceae, they are one of the two largest families of flowering plants. The Orchidaceae have about 28,000 currently accepted species, distributed in about 763 genera.The determination of which family is larger is still under debate, because verified data on the members of such enormous families are continually in flux. Regardless, the number of orchid species nearly equals the number of bony fishes and is more than twice the number of bird species, and about four times the number of mammal species.

The family encompasses about 6–11% of all seed plants. The largest genera are Bulbophyllum (2,000 species), Epidendrum (1,500 species), Dendrobium (1,400 species) and Pleurothallis (1,000 species). It also includes Vanilla–the genus of the vanilla plant, the type genus Orchis, and many commonly cultivated plants such as Phalaenopsis and Cattleya. Moreover, since the introduction of tropical species into cultivation in the 19th century, horticulturists have produced more than 100,000 hybrids and cultivars.

Orchids are easily distinguished from other plants, as they share some very evident, shared derived characteristics, or synapomorphies. Among these are: bilateral symmetry of the flower (zygomorphism), many resupinate flowers, a nearly always highly modified petal (labellum), fused stamens and carpels, and extremely small seeds.

Rhizanthella gardneri

Rhizanthella gardneri, also known as Western Underground Orchid, is a plant in the orchidfamily, discovered in the spring of 1928 in the wheatbelt of Western Australia.Jack Trott had bent to investigate an odd crack that had appeared in his garden's soil, and had noticed a sweet smell that arose from the ground. Scraping away the soil, he soon uncovered a tiny white flower, about half an inch across, growing underground. What he had found was an entirely new type of orchid. The discovery generated such excitement that a wax model was toured around the British Isles.

The white leafless plant is made up of a fleshy underground storage stem (or tuber), which produces flower head consisting of around 150 tightly packed, tiny flowers. Unlike any other orchid in Australia, the Western Australian underground orchid remains completely underground for its whole life. Not being able to obtain the sun's energy, it instead feeds on the broom honeymyrtle, a shrub. It is linked to it by a mycorrhizal fungus named Thanatephorus gardneri.This particular orchid is a myco-heterotroph as it relies completely on the broom honeymyrtle and fungus for its nutrients and carbon dioxide. Having received this from the fungus the plant is then able to convert the water, nutrients and carbon dioxide into the energy needed for growth and maintenance.

The plant blooms in May and June and measures 2.5–3 cm (1–1 1⁄4 in). The flower head contains 8 to 90 small dark maroon flowers.Rhizanthella gardneri reproduces vegetatively by which it can produce three daughter plants. They also undergo sexual reproduction, and underground insects such as termites and gnats are known to pollinate the flowers, attracted by the fragrance. The pollinated flower will then take six months to mature. In all studied flowers these were not dispersed and eventually decayed, thus releasing their seeds.It may be, however, that native marsupials were important dispersal agents, but substantial findings are hard to come by as only 19 mature specimens of the orchid are known to currently exist in the wild and only 300 specimens have been collected to date

Hexalectris colemanii

Hexalectris colemanii (Coleman's crested coralroot) is a terrestrial, myco-heterotrophic orchid lacking chlorophyll and subsisting entirely on nutrients obtained from mycorrhizal fungi in the soil. It is a very rare species endemic to southern Arizona, known from only three counties (Pima, Cochise and Santa Cruz). It is closely related to H. revoluta and the two are sometimes considered varieties of the same species.

Thelymitra jonesii

Thelymitra jonesii, commonly called the skyblue sun orchid, is a species of orchid that is endemic to Tasmania. It has a single erect, fleshy, linear, dark green leaf and up to six relatively small light blue to azure blue flowers with darker veins. It is a rare orchid known from only four scattered locations in moist coastal heath.

Thelymitra jonesii is a glaucous, tuberous, perennial herb with a single erect, fleshy, channelled, grass-like linear leaf 60–210 mm (2–8 in) long and 3– 6 mm (0.1–0.2 in) wide with a purplish base. Up to six light blue to azure blue flowers with darker veins, 13–27 mm (0.5–1 in) wide are arranged on a flowering stem 80–400 mm (3–20 in) tall. The sepals and petals are 6–13 mm (0.2–0.5 in) long and 2–8 mm (0.08–0.3 in) wide. The column is blue to purplish, 3–5 mm (0.1–0.2 in) long and 1.5–2.5 mm (0.06–0.1 in) wide with flanges on the side. The lobe on the top of the anther is blackish with a yellow fleshy, toothed tip and the side lobes have mop-like tufts of white or purplish hairs. The flowers are insect pollinated and open on warm days. Flowering occurs from September to December and flowering is more prolific after fire the previous summer.
