Rare flowers bloom in the world


1 Jade Vine :Strongylodon macrobotrys, commonly known as jade vineemerald vine or turquoise jade vine, is a species of leguminous perennial woodyvine, a native of the tropical forests of the Philippines, with stems that can reach up to 18 m in length. Its local name is "tayabak".A member of the Fabaceae (the pea and bean family), it is closely related to beans such as kidney bean and runner bean.

2. Rafflesia arnoldii
Rafflesia arnoldii is a member of the genus Rafflesia. It is noted for producing the largest individual flower on earth, and a strong odor of decaying flesh - the latter point earning it the nickname of "corpse flower". It is an endemic plant that occurs only in the rainforests of Sumatra Island, Indonesia. Although there are some plants with larger flowering organs like the Titan Arum and Talipot palm, those are technically clusters of many flowers.
Rafflesia arnoldii (Indonesian: padma raksasa) is one of the three national flowers in Indonesia, the other two being the white jasmine and moon orchid.It was officially recognized as a national "rare flower" (Indonesian: puspa langka) in Presidential Decree No. 4 in 1993


 3 .Silene tomentosa
Silene tomentosa, the Gibraltar campion, is a very rare flowering plant of the genus Silene and the family Caryophyllaceae. It is a woody-based perennialabout 40cm high, with bilobed flowers ranging from pink to pale violet and is endemic to Gibraltar

4 .Franklinia alatamaha
Franklinia is a monotypic genus in the tea plant family, Theaceae. The sole species in this genus is a flowering tree, Franklinia alatamaha, commonly called the Franklin tree, and native to the Altamaha River valley in Georgia in the southeastern United States. It has been extinct in the wild since the early 19th century, but survives as a cultivated ornamental tree.
In the past, some botanists have included Franklinia within the related genus Gordonia. The southeastern North American species Gordonia lasianthusdiffers in having evergreen foliage, flowers with longer stems, winged seeds, and conical seed capsules. (Franklinia was often known as Gordonia pubescens until the middle of the 20th century.)
Franklinia is now thought to be closer in relation to the Asian genus Schima. Recent DNA studies and examinations of floral ontogeny in the Theaceae place Franklinia together with Gordonia and Schima in a subtribe. (Tsou 1998). Hybrid crosses have been produced between Franklinia alatamaha andGordonia lasianthus, and between Franklinia alatamaha and Schima argentea. (Orton 1977; Ranney et al. 2003).
5. Lotus berthelotii

Lotus berthelotii is a perennial plant endemic to the Canary Islands, in the genus Lotus. This plant is either extinct in the wild or persists as a few individuals. In 1884 it was already classed as "exceedingly rare" and plant collection probably hastened its decline.

6 .Cosmos atrosanguineus
Cosmos atrosanguineus (Chocolate Cosmos) is a species of Cosmos, native to Mexico, where it is extinct in the wild. The species was introduced into cultivation in 1902, where it survives as a single clone reproduced by vegetative propagation.
It is a herbaceous perennial plant growing to 40-60 cm tall, with a fleshy tuberous root. The leaves are 7-15 cm long, pinnate, with leaflets 2-5 cm long. The flowers are produced in a capitulum 3-4.5 cm diameter, dark red to maroon-dark brown, with a ring of six to ten (usually eight) broad ray florets and a center of disc florets; they have a light vanillin fragrance (like many chocolates), which becomes more noticeable as the summer day wears on.

7 .Kokai cookei
Kokia cookei is a small, deciduous tree commonly known as the kokiʻoMolokaʻi treecottonCooke's kokiʻo, or Molokaʻi kokiʻo. It is considered one of the rarest and most endangered plant species in the world. Even when first found in the 1860s, only three trees could be located. It was presumed extinct in the 1950s when the last surviving seedling perished. However, in 1970, a single plant was discovered on the same Kauluwai estate where the "last" individual grew, presumably a surviving relict of one of the plants previously cultivated there. Although this tree was destroyed in a fire in 1978, a branch that was removed earlier was grafted onto the related, and also endangered, Kokia kauaiensis. Currently there exist about 23 grafted plants.
It is only known to have existed in the lowlands of western Molokaʻi in the Hawaiian Islands. Presumably, its native habitat was lowland dry forests on theleeward western end of the island; this was all but cut down by Polynesian settlers about the year 1000 AD to make room for agriculture. It seems to have been noted by these settlers, as suggested by the native name hau heleʻula ("entirely red hau").The three trees initially found grew nearMahana, northeast of Puu Nana at approximately 200 metres (660 ft) elevation.
Although the original forest ecosystem was destroyed and replaced by shrubland with plants like native ʻilieʻe (Plumbago zeylanica) and introduced flora, Molokaʻi kokiʻo survived initially. It seems to have had some tolerance to habitat change, enabling it to hang on until the 19th century.
8 .Cypripedium calceolus
Cypripedium calceolus is a lady's-slipper orchid, and the type species of the genus Cypripedium.
It has a widespread distribution from Europe east through Asia to the Pacific Ocean and is typically is found in open woodland on moist calcareous soils. In continental Europe it is also found growing in the decomposed humus of semi-shaded woodland cover on limestone. It has declined over much of theEuropean part of its range, and as a result is legally protected in a number of countries.
In Britain it was formerly a reasonably widespread plant across northern England, particularly the limestone area of the Yorkshire Dales. By the late 20th century it had declined to just a single plant in one location in the dales. While the virtual extinction of the Lady's-slipper orchid from its historical range in Britain is often blamed on uprooting by gardeners and botanists, it is also the case that its preferred habitat shrunk markedly with human clearance of woodland from the limestone landscape, and the grazing of sheep will have finished it off. A reintroduction program for the Lady’s-slipper orchid is in place, and has led to a population of hundreds of plants as of 2003.
The Norwegian municipality of Snåsa has a Cypripedium calceolus in its coat-of-arms.
In Pavel Ivanovich Melnikov's "In the Forests", a znakharka (Russian wise woman) calls this Adam's head, Adam's grass, and Cuckoo's slippers and says it's good for every ill including driving away evil spirits.
Cypripedium calceolus sensu stricto ("in the strict sense") does not occur in North America. The closely related Cypripedium parviflorum and C. pubescens are often still referred to as subspecies or variety of C. calceolus.

9 .Epipogium aphyllum
The Ghost Orchid (Epipogium aphyllum) - not to be confused with the American Ghost Orchid (Dendrophylax lindenii) - is a hardy myco-heterotrophicorchid lacking chlorophyll.
It is famous for its unpredictable appearance; in many localities it has been seen just once. It is found in beech, oak, pine and spruce forests on base-rich soils. It is a rare and critically endangered plant in habitat, and is believed to be extinct throughout much of its former range, although it has been recently confirmed in the United Kingdom, an area where the plants were believed to have gone extinct.
The plants are protected in many locales, and removing the plants from habitat or disturbing the plants can be a very serious matter in many jurisdictions, even for scientific study. These plants are exceptionally rare and should never be removed from habitat or disturbed.
