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. • BF1 Orchids Gallery Malaysia • https://shop.bf-1.com/ • Best Formula Industries • ( Incorporated Since : 27th Dec 2002 ) • ( Company No : 002150621-D ) • BF1 Office And Showroom • Lot : 146, Jalan Segambut, • 51200 Kuala Lumpur, Malaysia. • Location Map : • https://goo.gl/maps/bxC2BvaNVAy • BF1 Contact • Tel : +603-6257 6048 • Fax : +603-6241 0436 • Operation Hours : • Mon - Fri = 10am - 6.30pm • Sat = 10am - 5pm • Mobile : ( SMS or Whatsapp ) • English : +60192618000 • Bahasa Malaysia : +60123590344 • 中文 * 普通话 : +60173872066 • Email: [email protected] • 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. • Stem and roots • Germinating seeds of the temperate orchid Anacamptis coriophora. The protocorm is the first organ that will develop into true roots and leaves. • All orchids are perennial herbs that lack any permanent woody structure. They can grow according to two patterns: • Monopodial: The stem grows from a single bud, leaves are added from the apex each year and the stem grows longer accordingly. The stem of orchids with a monopodial growth can reach several metres in length, as in Vanda and Vanilla. • Sympodial: Sympodial orchids have a front (the newest growth) and a back (the oldest growth). The plant produces a series of adjacent shoots, which grow to a certain size, bloom and then stop growing and are replaced. Sympodial orchids grow laterally rather than vertically, following the surface of their support. The growth continues by development of new leads, with their own leaves and roots, sprouting from or next to those of the previous year, as in Cattleya. While a new lead is developing, the rhizome may start its growth again from a so-called 'eye', an undeveloped bud, thereby branching. Sympodial orchids may have visible pseudobulbs joined by a rhizome, which creeps along the top or just beneath the soil. • Anacamptis lactea showing the two tubers • Terrestrial orchids may be rhizomatous or form corms or tubers. The root caps of terrestrial orchids are smooth and white. • Some sympodial terrestrial orchids, such as Orchis and Ophrys, have two subterranean tuberous roots. One is used as a food reserve for wintry periods, and provides for the development of the other one, from which visible growth develops. • In warm and constantly humid climates, many terrestrial orchids do not need pseudobulbs. • Epiphytic orchids, those that grow upon a support, have modified aerial roots that can sometimes be a few meters long. In the older parts of the roots, a modified spongy epidermis, called velamen, has the function of absorbing humidity. It is made of dead cells and can have a silvery-grey, white or brown appearance. In some orchids, the velamen includes spongy and fibrous bodies near the passage cells, called tilosomes. • The cells of the root epidermis grow at a right angle to the axis of the root to allow them to get a firm grasp on their support. Nutrients for epiphytic orchids mainly come from mineral dust, organic detritus, animal droppings and other substances collecting among on their supporting surfaces.
