Cypripedioideae

Lady's slipper orchids (also known as lady slipper orchids or slipper orchids) are orchids in the subfamily Cypripedioideae, which comprises 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.

Taxonomy

Unlike most other orchids, slipper orchids have two fertile anthers — they are "diandrous". For that reason, experts have debated whether this clade should be classified within the orchid family (Orchidaceae), or whether they should compose a separate family altogether called Cypripediaceae. Around the year 2000, molecular phylogenetics and DNA sampling have come to play an increasingly important role in classification. This has led to the conclusion that recognition of a distinct Cypripediaceae family would be inappropriate.

Orchidaceae

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. Orchidaceae has about 27,800 currently accepted species, distributed in about 880 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 also 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).

The family also includes Vanilla (the genus of the vanilla plant), Orchis (type genus), 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 (album)

Orchids is the debut album of dream pop band Astral. It contained ten songs and was released in 2003. The title track, Orchids, is a highly melodic instrumental slightly reminiscent of space rock. The record was mixed at Stout Recording Studio in Oakland, California and was engineered by Randy Burk, who in the past had worked with Swingin' Utters The album charted #119 on the CMJ 200. Two songs, Orchids and Raining Down, were preloaded on the Rio Carbon MP3 Players.
