Since the time of Darwin, evolutionary biologists have been fascinated by the spectacular adaptations to insect pollination exhibited by orchids. However, despite being the most diverse plant family on Earth, the Orchidaceae lack a definitive fossil record and thus many aspects of their evolutionary history remain obscure. Here we report an exquisitely preserved orchid pollinarium (of Meliorchis caribea gen. et sp. nov.) attached to the mesoscutellum of an extinct stingless bee, Proplebeia… 

Age estimation for the genus Cymbidium (Orchidaceae: Epidendroideae) with implementation of fossil data calibration using molecular markers (ITS2 & matK) and phylogeographic inference from ancestral area reconstruction

This study examines a genus level analysis by integrating different molecular matrices to existing fossil data on orchids in a molecular Bayesian relaxed clock employed in BEAST and assessed divergence times for the genus Cymbidium with a focus on evolutionary history of photosynthetic characters.

The Apostasia genome and the evolution of orchids

New light is shed on the genetic mechanisms underpinning key orchid innovations, including the development of the labellum and gynostemium, pollinia, and seeds without endosperm, as well as the evolution of epiphytism; reveals relationships between the Orchidaceae subfamilies; and helps clarify the evolutionary history of orchids within the angiosperms.

Evolution and Biogeography of the Slipper Orchids: Eocene Vicariance of the Conduplicate Genera in the Old and New World Tropics

The evolutionary and biogeographical history of the slipper orchids is investigated, which represents a monophyletic subfamily of the orchid family and comprises five genera that are disjunctly distributed in tropical to temperate regions.

Molecular phylogenetics, evolution of sexual systems and historical biogeography of Darwin's favourite orchids (Catasetinae) and Swan orchids (Cycnoches Lindl.)

This dissertation is focused on three puzzling aspects of plant evolutionary biology, specifically the phylogenetic incongruence between nuclear and plastid genomes, the evolution of sexual systems, and lineage migration and isolation through time.

Recent origin of Neotropical orchids in the world’s richest plant biodiversity hotspot

The majority of Andean orchid lineages only originated in the last 15 million years, and it is suggested that mountain uplift promotes species diversification across all elevational zones.

Recent origin and rapid speciation of Neotropical orchids in the world's richest plant biodiversity hotspot

It is suggested that mountain uplift promotes species diversification across all elevational zones, and the majority of Andean orchid lineages only originated in the last 20–15 million yr.

An Indomalesian origin in the Miocene for the diphyletic New World jewel orchids (Goodyerinae, Orchidoideae): molecular dating and biogeographic analyses document non-monophyly of the Neotropical genera

The well-supported phylogenetic topology suggests two independent dispersal events to the New World from the Indomalesian region during the Miocene, which putatively prevented vicariance events imposed by the expansion of the Chacoan region as previously detected for epiphytic Orchidaceae.

By land and by tree: Pollinator taxa diversity of terrestrial and epiphytic orchids

There are approximately 30,000 species in the family Orchidaceae, with some species growing terrestrially and others growing as epiphytes. Though the pollination biology of many of these species is

A review of orchid pollination studies in China

Future studies should involve additional disciplines and techniques, such as chemecologic, electrophysiologic, genomic, transcriptomic, and proteomic methods, to evaluate the floral features that attract specific pollinators and to elucidate the patterns of Chinese orchid pollination.

Although the fossils are much smaller than their modern relatives, the precise and dramatic correspondence between the fossil floral morphology and that of modern Victoria flowers suggests that beetle entrapment pollination was present in the earliest part of the Late Cretaceous.

The Orchids: Natural History and Classification

This lively examination of the structure, classification, evolution, and ecology of the Orchidaceae will appeal to anyone with an eye for beauty or a bent for natural history, and will provide professional biologists and amateur orchidists alike with a deeper understanding of this, the largest flowering family in the plant kingdom.
