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. [12] The first classification that was based on cladistic analysis of DNA data was published by Chase et alii in 2003. [13] An update to ...
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.
A Phalaenopsis flower. Orchids are easily distinguished from other plants, as they share some very evident derived characteristics or synapomorphies.Among these are: bilateral symmetry of the flower (zygomorphism), many resupinate flowers, a nearly always highly modified petal (labellum), fused stamens and carpels, and extremely small seeds.
Three goals of plant taxonomy are the identification, classification and description of plants. The distinction between these three goals is important and often overlooked. Plant identification is a determination of the identity of an unknown plant by comparison with previously collected specimens or with the aid of books or identification manuals.

Phalaenopsis orchid. Orchidales is an order of flowering plants. In taxonomical systems, this is a relatively recent name as early systems used descriptive botanical names for the order containing the orchids. [1] The Bentham & Hooker and the Engler systems had the orchids in order Microspermae while the Wettstein system treats them as order ...

Epidendroideae is a subfamily of plants in the orchid family, Orchidaceae. Epidendroideae is larger than all the other orchid subfamilies together, comprising more than 15,000 species in 576 genera. Most epidendroid orchids are tropical epiphytes, typically with pseudobulbs.
