SummaryThe digitate-tubered clade (Dactylorhiza s.l. plus Gymnadenia s.l.) within subtribe Orchidinae is an important element of the North-temperate orchid flora and has become a model system for studying the genetic and epigenetic consequences of organism-wide ploidy change. Here, we integrate morphological phylogenetics with Sanger sequencing of nrITS and the plastid region trnL-F in order to explore phylogenetic relationships and phenotypic character evolution within the clade. The resulting… 
In situ morphometric survey elucidates the evolutionary systematics of the orchid genus Gymnadenia in the British Isles
TLDR
A large-scale morphometric survey of Gymnadenia species is used to determine whether phenotypic differentiation exists alongside their documented genotypic and ecological differentiation, seeking the most diagnostic morphological characters.
Challenges of applying monophyly in the phylogenetic shallows: taxonomic reappraisal of the Dactylorhiza maculata group
The first study of the taxonomically critical European orchid genus Dactylorhiza to use next-generation DNA sequencing generated the statistically best-supported reconstruction of its phylogeny to
Phylogenomic Relationships of Diploids and the Origins of Allotetraploids in Dactylorhiza (Orchidaceae)
TLDR
This work first investigates circumscription and relationships of diploid species in the genus using coalescent and maximum likelihood methods, and then group 16 allotetraploids by maximum affiliation to their putative parental diploids, implementing a method based on genotype likelihoods.
Morphometric comparison of British Pseudorchis albida with Icelandic P. straminea (Orchidaceae: Orchidinae)
TLDR
It is found no evidence that P. straminea (or ‘P. tricuspis’) occurs in the British Isles; nonetheless, this species should continue to be sought in suitable habitats in northern Scotland and has the potential to become a valuable model system for the study of speciation and subsequent inter-/post-glacial migration.
A Multilocus Phylogeny of Daphniphyllum (Daphniphyllaceae)
TLDR
The results indicate that some hybridization events might have occurred in the evolutionary history of the genus Daphniphyllum, and support the classification hypotheses of D. glaucescens Blume in a strict sense but not in a broad sense.
Systematics and conservation of British and Irish orchids: a "state of the union" assessment to accompany Atlas 2020
Prompted by concurrent completion of the latest plant atlas for Britain and Ireland, the orchid flora of these islands is reviewed in detail, focusing on 21st century progress in both systematics
Morphological variability, cytotype diversity, and cytogeography of populations traditionally called Dactylorhiza fuchsii in Central Europe
TLDR
Qualitative morphological traits were inferred to be the most important drivers of morphological variation among the investigated plants, with the most striking differences in flower colouration and leaf spotting.
A Phylogenomic Analysis of the Floral Transcriptomes of Sexually Deceptive and Rewarding European Orchids, Ophrys and Gymnadenia
TLDR
A phylogenomic approach is employed to address open questions of phylogenetic relationships within the genera O. insectifera within the Ophrys phylogeny and the placement of “Nigritella”-type morphologies within the phylogeny of Gymnadenia.
The use of phylogenomic tools to investigate diploid and polyploid evolution in Dactylorhiza and other orchids
Die Untersuchung phylogenetischer Beziehungen von sich kurzlich entwickelten Gruppen stellt eine grose Herausforderung dar, insbesondere bei fortlaufender Hybridisierung. Allo-polyploide Organismen

Phylogenetics of subtribe Orchidinae s.l. (Orchidaceae; Orchidoideae) based on seven markers (plastid matK, psaB, rbcL, trnL-F, trnH-psba, and nuclear nrITS, Xdh): implications for generic delimitation
TLDR
This work proposes to recognize five genera in the Ponerorchis alliance: Hemipilia, Poner orchis s.l., Sirindhornia, Shizhenia and Tsaiorchis, and concludes that Habenaria should be split into two genera based on morphological characters and geographical distribution.
Molecular phylogenetics and morphological reappraisal of the Platanthera clade (Orchidaceae: Orchidinae) prompts expansion of the generic limits of Galearis and Platanthera.
TLDR
Resolution of major groups should facilitate future species-level research on the Platanthera clade by combining implicit assessment of morphological divergence with explicit assessment of molecular divergence.
Molecular phylogeny and evolutionary history of the Eurasiatic orchid genus Himantoglossum s.l. (Orchidaceae).
TLDR
Plastid sequence divergence is broadly consistent with prior, morphologically circumscribed taxa and indicates a division between H. hircinum-adriaticum to the west of the Carpathians and H. jankae-caprinum (plus local endemics) to the east, a distinction also suggested by nrITS ribotypes.
Phylogenetic context, generic affinities and evolutionary origin of the enigmatic Balkan orchid Gymnadenia frivaldii Hampe ex Griseb
TLDR
Molecular phylogenetic analysis using the ITS region of rDNA reveals a large disparity between the two genera and demonstrates that frivaldii is embedded well within Gymnadenia s.s. Nigritella, suggesting one of three cases of independent paedomorphic floral reduction inferred in the genus.
Phylogeny and classification of the East Asian Amitostigma alliance (Orchidaceae: Orchideae) based on six DNA markers
TLDR
A new framework on the complex phylogenetic relationships between Amitostigma and other genera traditionally included in its alliance is provided; based on which, the entire Amitstigma alliance is combined into a morphologically and molecularly circumscribed Amitost Sigma sensu latissimo that also contains seven molecularly circumcised sections.
Phylogenetics of tribe Orchideae (Orchidaceae: Orchidoideae) based on combined DNA matrices: inferences regarding timing of diversification and evolution of pollination syndromes.
TLDR
The results indicate that ancestral Orchidinae were hymenopteran-pollinated, food-deceptive plants and that these traits have been dominant throughout the evolutionary history of the subtribe in the Mediterranean.

Clarified relationship between Dactylorhiza viridis and Dactylorhiza iberica renders obsolete the former genus Coeloglossum (Orchidaceae: Orchidinae)
TLDR
Both orchid species possess multiple morphological character states that are unique within the genus Dactylorhiza, but it is argued that greater phenotypic disparity is commonly the case in early-divergent lineages per se.
