    serch.it?q=Orchidaceae

    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.

    Ansellia is considered a monotypic genus of orchid, with only one species, Ansellia africana, commonly known as African ansellia or leopard orchid, however, it is in fact a complex group of species which share common floral structure and growth habit. The plants are found throughout neotropical and subtropical Africa. It was named after John Ansell, an English assistant botanist. who found the first specimens in 1841 on the Fernando Po Island in West Africa. This genus is abbreviated as Aslla in horticultural trade. It is referred to along with Grammatophyllum as a "trash basket" orchid due to its odd habit of creating a makeshift container of aerial roots to catch falling leaf litter for nutrients.
