Orchidaceae is a diverse and widespread family of flowering plants with blooms that are often colourful and often fragrant, commonly known as the orchid family. Along with the Asteraceae, they are one of the two largest families of flowering plants, with between 21,950 and 26,049 currently accepted species, found in 880 genera. The determination of which family is larger is still under debate. The largest genera are Bulbophyllum, Epidendrum (1,500 species), Dendrobium (1,400 species) and Pleurothallis (1,000 species).

determination of which family is larger is still under debate, because verified
data on the members of such enormous families are continually in flux. Source

Sikkim, and China (Gansu, Guizhou, Sichuan, Tibet, Yunnan). It is nice and
cool. This gives us a sweet fragrane and refresh our mind heartly. Source
Catasetum, abbreviated as Ctsm in horticultural trade, is a genus of showy epiphytic Orchids, family, subfamily Epidendroideae, tribe Cymbidieae, subtribe Catasetinae, with 166 species, many of which are highly prized in horticulture. Species of the genus Catasetum occur from Mexico to Argentina, including much of Central America, the West Indies, and South America. The largest number of species is in Brazil. There are rare cases in which a single plant in intermediate conditions will produce both male and female flowers. These flowers are markedly different in size and color. At first, taxonomists even thought they were dealing with different species, a puzzle which Charles Darwin resolved when writing Fertilisation of Orchids. Source
Lady's slipper orchids are orchids in the subfamily Cypripedioideae, which includes the genera Cypripedium, Mexipedium, Paphiopedilum, Phragmipedium and Selenipedium. They are characterised by the slipper-shaped pouches (modified labellums) of the flowers , the pouch traps insects so they are forced to climb up past the staminode, behind which they collect or deposit pollinia, thus fertilizing the flower. Unlike other orchids, Cypripedioideae have two fertile anthers, they are "diandrous". This subfamily has been considered by some to be a family Cypripediaceae, separate from the Orchidaceae. The subfamily Cypripedioideae is monophyletic and consists of five genera. The Cypripedium genus is found across much of North America, as well as in parts of Europe and Asia. The state flower of Minnesota is the showy lady's slipper (Cypripedium reginae). The pink lady's slipper is also the official provincial flower of the Canadian province of Prince Edward Island.
