Question: Are both Brassocattleya and Buckinghamia orchids?
Context: Calochilus, commonly known as beard orchids, is a genus of about 30 species of plants in the orchid family, Orchidaceae.  Beard orchids are terrestrial, herbs with a single leaf at the base of the plant, or no leaves.  Their most striking feature is a densely hairy labellum, giving rise to their common name.  Beard orchids, unlike some other Australian orchids, do not reproduce using daughter tubers, but self-pollinate when cross-pollination has not occurred.  Most species occur in Australia but some are found in New Zealand, New Guinea and New Caledonia. Thelymitra, commonly known as sun orchids, is a genus of more than 100 species of plants in the orchid family, Orchidaceae.  Unlike most other orchids, sun orchids lack a highly modified labellum and all three petals are similar in size, shape and colour.  The column is, however highly modified and usually has prominent wings or glands which are helpful in identifying the species.  Most sun orchids close their flowers at night, in cloudy or cool weather, giving rise to their common name.  The scientific name means "woman's hood" and refers to the hooded column present in most, but not all species.  Most species are endemic to Australia although some are found as far from there as the Philippines and Indonesia.  The type species, "Thelymitra longifolia", the first to be formally described, was collected in New Zealand. Caladenia, commonly known as spider orchids, is a genus of 350 species of plants in the orchid family, Orchidaceae.  Spider orchids are terrestrial herbs with a single hairy leaf and a hairy stem.  The labellum is fringed or toothed in most species and there are small projections called calli on the labellum.  The flowers have adaptations to attract particular species of insects for pollination.  The genus is divided into three groups on the basis of flower shape, broadly, spider orchids, zebra orchids and cowslip orchids, although other common names are often used.  Although they occur in other countries, most are Australian and 136 species occur in Western Australia, making it the most species-rich orchid genus in that state. Buckinghamia is a genus of only two known species of trees, belonging to the plant family Proteaceae.  They grow naturally only (endemic) in the rainforests of the wet tropics region of north eastern Queensland, Australia.  The ivory curl flower, "B. celsissima", is the well known, popular and widely cultivated species in gardens and parks, in eastern and southern mainland Australia, and additionally as street trees north from about Brisbane.  The second species, "B. ferruginiflora", was only recently described in 1988. 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. Microtis, commonly known as onion orchids or mignonette orchids is a genus of about 20 species of plants in the orchid family, Orchidaceae.  Onion orchids are terrestrial herbs with a single leaf at the base of the plant.  They are similar to orchids in the genus "Prasophyllum" in that they have an onion-like leaf.  The flowers are small but often scented and attractive to their insect pollinators.  They are widespread in Asia, Australia and some Pacific islands. Brassocattleya or Brasso-cattleya, abbreviated Bc.  in the horticultural trade, is an intergeneric orchid hybrid derived from the genera "Brassavola" and "Cattleya". Cypripedium is a genus of 58 species and nothospecies of hardy orchids; it is one of five genera that together compose the subfamily of lady's slipper orchids (Cypripedioideae).  They are widespread across much of the Northern Hemisphere, including most of Europe (one species), Russia, China, Central Asia, Canada the United States, Mexico, and Central America.  They are most commonly known as slipper orchids or lady's slipper orchids; other common names include moccasin flower, camel's foot, squirrel foot, steeple cap, Venus' shoes, and whippoorwill shoe.  An abbreviation used in trade journals is "Cyp."  The word ""Cypripedium"" is derived from the Late Latin: "Cypris", from Ancient Greek: Κυπρις  "(Kypris)" , an early reference in Greek myth to Aphrodite, and Greek: "pedilon", meaning "sandal". William Henry Nicholls (23 July 1885 – 10 March 1951) was an Australian amateur botanist, authority on, and collector of Australian orchids.  An accomplished photographer and watercolourist, he contributed almost 100 articles on orchids to "The Victorian Naturalist", many of which described new species with line drawings.  He was working on producing a 24-volume illustrated monograph of all the orchids of Australia when he died.  Only four volumes were published shortly after his death but the entire work was published in a single book, "Orchids of Australia" in 1969.  Some of the many orchids described and named by Nicholls and retaining the name he gave them include "Caladenia caudata", "Caladenia echidnachila", "Caladenia ensata", "Caladenia ferruginea", "Caladenia magniclavata", "Caladenia ornata", "Caladenia praecox", "Caladenia radiata", "Pterostylis fischii", "Pterostylis hamiltonii", "Pterostylis hildii" and "Pterostylis tenuissima". Paracaleana commonly known as duck orchids, is a genus of flowering plants in the orchid family, Orchidaceae that is found in Australia and New Zealand.  The Australian species are found in all states but have not been recorded in the Northern Territory.  Orchids in this genus are similar to "Caleana major", but there are differences in the flowers and in the insects that pollinate them.  "Paraceleana" orchids, as well as hammer orchids ("Drakaea") are pollinated by male thynnid wasps.  Duck orchids have a single leaf and one or a few, dull-coloured, inconspicuous flowers.
