It reflects the considerable progress in orchid taxonomy that had been made since Dressler published his classification in 1993. In the 1990s, orchid taxonomy began to be influenced by molecular phylogenetics based on DNA sequences. The first molecular phylogenetic study to include a substantial sample of orchids was published in 1999. [13]
Prosthechea cochleata is the national flower of Belize, where it is known as the black orchid. [53] Lycaste skinneri has a white variety (alba) that is the national flower of Guatemala, commonly known as Monja Blanca (White Nun). Panama's national flower is the Holy Ghost orchid (Peristeria elata), or 'the flor del Espiritu Santo'.
Phalaenopsis (/ ˌ f æ l ɪ ˈ n ɒ p s ɪ s /), also known as moth orchids, [2] is a genus of about seventy species of plants in the family Orchidaceae.Orchids in this genus are monopodial epiphytes or lithophytes with long, coarse roots, short, leafy stems and long-lasting, flat flowers arranged in a flowering stem that often branches near the end.
Aerides, known commonly as cat's-tail orchids and fox brush orchids, is a genus belonging to the orchid family (Orchidaceae, subfamily Epidendroideae, tribe Vandeae, subtribe Aeridinae). It is a group of tropical epiphyte orchids that grow mainly in the warm lowlands of tropical Asia from India to southern China to New Guinea.
Orchid taxonomy is still being revised and each year about another 150 new species are being discovered. The list of genera alone currently stands just short of 1000 entries. From a cladistic point of view, the orchid family is considered to be monophyletic , i.e. the group incorporates all the taxa derived from an ancestral group.
In winter, the optimal temperature range is between 26 and 27 °C and 15-17 °C at night. Significant temperature differences are beneficial to Paphiopedilum rothschildianum; the region of Mount Kinabalu to which it is endemic has noticeable temperature drops and fluctuations which has caused the orchid to become adapted to this habitat type.

Dendrobium bigibbum, commonly known as the Cooktown orchid or mauve butterfly orchid, [3] is an epiphytic or lithophytic orchid in the family Orchidaceae. It has cylindrical pseudobulbs , each with between three and five green or purplish leaves and arching flowering stems with up to twenty, usually lilac-purple flowers.
Thermotolerance is the ability of an organism to survive high temperatures. An organism's natural tolerance of heat is their basal thermotolerance . [ 1 ] Meanwhile, acquired thermotolerance is defined as an enhanced level of thermotolerance after exposure to a heat stress.
