sentences: Duvalia is a succulent plant genus in the tribe Stapeliae, milkweed subfamily Asclepiadoideae, in the family Apocynaceae (dogbane).
Heterotaxis is a genus of orchids native to Latin America from central Mexico to Bolivia, and also to parts of the West Indies.
 One species extends into Florida ("H. sessilis", listed under synonym "Maxillaria crassifolia" in Flora of North America).
Maxillarieae is a large and complex tribe of orchids native to South and Central America.
 Within the tribe there are eight subtribes one of which is that of the genus "Maxillaria".
Nudol is a phenanthrenoid of the orchids "Eulophia nuda", "Eria carinata", "Eria stricta" and "Maxillaria densa".
Maxillaria, abbreviated as Max in the horticultural trade, is a large genus of orchids (family Orchidaceae).
 This is a diverse genus, with very different morphological forms.
 Their characteristics can vary widely.
Ornithidium donaldeedodii is a species of orchids "discovered" in April 2010 when DNA analysis showed that a wrongly labeled orchid at the University of California Botanical Garden in Berkeley, California, was actually a distinct new species.
 The "new" orchid, which had been mislabeled as "Maxillaria croceorubens" since the 1990s, was named after orchidologist Donald D. Dod (1912–2008), who collected the specimen in the 1980s in Haiti.
 The new orchid was officially described in "Lankesteriana", an international journal on orchidology, by authors James Ackerman of the University of Puerto Rico and W. Mark Whitten of the Florida Museum of Natural History.
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.
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.
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.
Camaridium is a genus of epiphytic orchids widespread across the West Indies and through Latin America from Mexico to Bolivia.
 One species extends into Florida ("C. vestitum", listed in Flora of North America under the synonym, "Maxillaria parviflora").
