Vanda coelestis is a species of orchid native to Cambodia, Thailand and Vietnam. [1]
These epiphytic herbs form distiched, hard, deeply grooved, arching leaves that are up to 17 cm long and 2 cm wide. The branched stems can grow up to 10-25 cm tall. The 20 to 50 fragrant, white, pink or blue flowers, 2.2 cm wide, are in dense, upright racemes. The spur is flat but the distal half is curved forward. [2]
The chromosome count of Vanda coelestis is 2n = 38. [3]
The former placement of this species within Rhynchostylis has been disputed. [2] One study identifies this species as the sister group to all other Rhynchostylis species on the basis of Amplified Fragment Length Polymorphism. [4]
The specific epithet coelestis, derived from the Latin caelum meaning the sky, heavenly, refers to the blue floral colouration. [2]
Pollination occurs during daytime through bees. [5]
In molecular biology, restriction fragment length polymorphism (RFLP) is a technique that exploits variations in homologous DNA sequences, known as polymorphisms, populations, or species or to pinpoint the locations of genes within a sequence. The term may refer to a polymorphism itself, as detected through the differing locations of restriction enzyme sites, or to a related laboratory technique by which such differences can be illustrated. In RFLP analysis, a DNA sample is digested into fragments by one or more restriction enzymes, and the resulting restriction fragments are then separated by gel electrophoresis according to their size.
Vanda, abbreviated in the horticultural trade as V., is a genus in the orchid family, Orchidaceae. There are 90 species, and the genus is commonly cultivated for the marketplace. This genus and its allies are considered to be among the most specifically adapted of all orchids within the Orchidaceae. The genus is highly prized in horticulture for its showy, fragrant, long-lasting, and intensely colorful flowers. Vanda species are widespread across East Asia, Southeast Asia, and New Guinea, with a few species extending into Queensland and some of the islands of the western Pacific.
Ribosomal DNA (rDNA) is a DNA sequence that codes for ribosomal RNA. These sequences regulate transcription initiation and amplification, and contain both transcribed and non-transcribed spacer segments.
Victoria cruziana is a tropical species of flowering plant, of the Nymphaeaceae family of water lilies native to South America, primarily Brazil, Bolivia, Argentina and Paraguay.
Cipocereus is a genus of cacti from Brazil. These species were previously included in the genera Pilosocereus and Cereus.
Crocus sativus, commonly known as saffron crocus or autumn crocus, is a species of flowering plant in the iris family Iridaceae. A cormous autumn-flowering cultivated perennial, unknown in the wild, it is best known for the culinary use of its floral stigmas as the spice saffron. Human cultivation of saffron crocus and the trade and use of saffron have endured for more than 3,500 years and span different cultures, continents, and civilizations.
Epidendrum radicans is a species of orchid. Common names include ground-rooting epidendrum, fire-star orchid, rainbow orchid, and reed-stem epidendrum. It is a common roadside weed at middle elevations in Central America. It is a crucifix orchid, often confused with many other members of the section Schistochila, including E. calanthe, E. cinnabarinum, E. denticulatum, E. erectum, E. fulgens, E. ibaguense, E. imatophyllum, E. incisum, E. schomburgkii, E. secundum, and E. xanthinum, among others. The diagnostic characteristic of E. radicans is its tendency to sprout roots all along the length of the stem; other crucifix orchids only produce roots near the base. Additionally, E. radicans flowers are resupinate, unlike the members of the Epidendrum secundum complex, E. fulgens, and many other crucifix orchids. E. radicans also differs from E. secundum by bearing no nectar in the flower.
Holcoglossum (Holc.) is a genus of orchids, in the family Orchidaceae. It is native from Assam through mainland China to Taiwan and Indo-China.
Schizanthus, also called butterfly flower, fringeflower, poor-man's-orchid, is a genus of plants in the nightshade family, Solanaceae.
Rhynchostylis is a genus in the orchid family (Orchidaceae), closely allied to the genus Vanda and comprising four currently accepted species native to the Indian Subcontinent, China, Indochina, Malaysia, Indonesia and the Philippines.
Rhynchostylis gigantea is a species of orchid. This species was first described in 1896 by John Lindley and is native to Borneo, Myanmar, Thailand, Peninsular Malaysia, Laos, Cambodia, Vietnam, China (Hainan) and the Philippines.
Rhynchostylis retusa is an orchid, belonging to the Vanda alliance. The inflorescence is a pendant raceme, consisting of more than 100 pink-spotted white flowers. The plant has a short, stout, creeping stem carrying up to 12, curved, fleshy, deeply channeled, keeled, retuse apically leaves and blooms on an axillary pendant to 60 cm (24 in) long, racemose, densely flowered, cylindrical inflorescence that occurs in the winter and early spring. It is famous for its use as a hair-ornament worn by Assamese women during folk dance Bihu on the onset of spring.
Diversity Arrays Technology (DArT) is a high-throughput genetic marker technique that can detect allelic variations to provides comprehensive genome coverage without any DNA sequence information for genotyping and other genetic analysis. The general steps involve reducing the complexity of the genomic DNA with specific restriction enzymes, choosing diverse fragments to serve as representations for the parent genomes, amplify via polymerase chain reaction (PCR), insert fragments into a vector to be placed as probes within a microarray, then fluorescent targets from a reference sequence will be allowed to hybridize with probes and put through an imaging system. The objective is to identify and quantify various forms of DNA polymorphism within genomic DNA of sampled species.
Vanda falcata, also known as 风兰 in Chinese, 풍란 (pungnan) in Korean, 風蘭 (fūran) in Japanese, or the wind orchid in English, is a species of orchid found in China, Korea, and Japan. It was formerly classified in the genus Neofinetia.
Pachycereus pecten-aboriginum is a columnar cactus plant native to Mexico. They can grow up to 15 m (49 ft) high. The trunk of this species is 1.2 to 5.0 m tall and the fruits are large and burr-like. The specific name, pecten-aboriginum, is from the Latin, and means "native combs". It was inspired by the use of the fruits as hair combs.
Ixia monadelpha, also known as the pied kalossie or bontkalossie, is an endangered species of geophyte found in wet sandy flats in the southwestern Cape of South Africa.
Hippeastrum calyptratum is a flowering perennial herbaceous bulbous plant, in the family Amaryllidaceae, native to Brazil.
Vanda wightii is a species of orchid from southern India and Sri Lanka. For some time it was thought to be extinct after being described in 1849. The species was however rediscovered and it is now known from India. It is closely related to Vanda thwaitesii. The species was named by Reichenback after the botanist and collector Robert Wight. 1.
Scilla amoena, the star hyacinth or squill, is a species of flowering plant plant in the genus Scilla.
Myosotis pansa subsp. praeceps is a subspecies of flowering plant in the family Boraginaceae, endemic to the North Island of New Zealand. Lucy Moore described the variety M. petiolata var. pansa in 1961, and it was transferred to a subspecies of M. pansa by Heidi Meudt, Jessica Prebble, Rebecca Stanley and Michael Thorsen in 2013. Plants of this species of forget-me-not are perennial rosettes with partially bracteate inflorescences and white corollas with exserted stamens.
