Abstract:  Orchids are the largest family of flowering plants, encompassing several times as many species as birds or mammals. Because of their diversity, charisma, and threats from overcollection and habitat loss, they are a key group in conservation. Nevertheless, preservation of this group is plagued by taxonomic problems, particularly in Europe, where new taxa are actively being described. We used a checklist of orchids to compare the taxonomic treatment of this family between Europe and…

Orchid classification has undergone a series of significant changes during the past decade as molecular phylogenetic studies have examined relationships at all taxonomic levels in the family. Today,

Pollination Syndromes in Mediterranean Orchids—Implications for Speciation, Taxonomy and Conservation

This review document how the different pollination syndromes of Mediterranean orchids can have a profound impact on the type of reproductive barriers among species, on floral phenotypic variation as the authors perceive it, on potentially related processes of species sorting and extinction and, consequently, should have a strong influence on the related conservation management programs.

Orchidaceae in the anthropogenic landscape of central Poland: Diversity, extinction and conservation perspectives

It has been shown that contemporary protection methods have failed to prevent the demise of these species in forest, meadow and bog habitats, which incidentally comprised most of those whose localities have been unconfirmed since 2000.

Factors determining the distribution of orchids – a review with examples from the Czech Republic

The natural environment has been significantly altered by human activity over the past few decades. There is evidence we are now experiencing the sixth mass extinction, as many species of plants and

Morphological, ecological and genetic aspects associated with endemism in the Fly Orchid group

Investigation of species boundaries in the Fly Orchid group (Ophrys insectifera sensu lato) by examining morphological, ecological and genetic evidence finds clear morphological and ecological factors segregating among these taxa; however, genetic differences were more ambiguous.

Chapter 8 Determinants of Orchid Occurrence : A Czech Example

Orchids are an endangered plant group, protected in the whole world. Questions of their conservation are therefore highly discussed, but not all factors affecting their survival and distribution are

Conservation recommendations from a large survey of French orchids

The French Atlas of Orchids published in autumn 2010 is a large-scale and intensive survey of orchid populations throughout the France territory, revealing demographic trends at the scale of the country.

Composition, geographical affinities and endemism of the Iberian Peninsula orchid flora

Very high levels of endemism were found in habitats peculiar to the Mediterranean Basin, indicating the relict status of its orchid flora.

Ecology, population genetics and conservation of the African violet

The results suggest that Saintpaulia has good reproductive performance in forests with low disturbance levels in the East Usambara Mountains, and high genetic diversities were observed in the populations, which suggest that they possess the variation that is needed for evolutionary responses in a changing environment.

Taxonomic complexity and breeding system transitions: conservation genetics of the Epipactis leptochila complex (Orchidaceae)

Comparisons with published data from the putative progenitor species for the autogamous taxa (the widespread, allogamous E. helleborine) suggest iterative origins of autogamy, rather than the self‐pollinating taxa all being merely mutational variants of a single autogaming lineage.

Species concept and guidelines for infraspecific taxonomic ranking in Dactylorhiza (Orchidaceae)

A positive correlation is found between the putative level of phylogenetic relationship and the degree of reproductive isolation within the genus Dactylorhiza, and taxa defined on each level are found to be morphologically recognizable.

DNA data and archidaceae systematics: A new phylogenetic classification

A new phylogenetic classification of Orchidaceae is proposed that accords with these newly discovered relationships and should help to focus other areas of orchid research and stimulate the creation of new hypotheses that will direct orchid researchers to new questions.

How many species of seed plants are there

The recent paper by Rafael Govaerts (2001) in Taxon 's Points of View and his omission of my counts in my recent Botanical Review paper (Thorne, 2000a) inspired me to recount (several times) the

How many species of seed plants are there

It is concluded that some recent figures overestimate the number of described seed plant species by more than 200,000, explained by an over-reliance on checklists and floristic studies that underestimate synonymy rates.

Taxonomic inflation: species concept or historical geopolitical bias?

Amplified fragment length polymorphisms (AFLP) reveal details of polyploid evolution in Dactylorhiza (Orchidaceae).

The AFLP data support the general picture of polyploid evolution in Dactylorhiza, i.e., that allotetraploid derivatives have arisen repeatedly as a result of hybridization beween the two parental groups, and relationships among them were partly correlated to morphologically based entities, but also to geographic distribution.
