DNA sequence data from plastid matK and trnL-F regions were used in phylogenetic analyses of Diurideae, which indicate that Diurideae are not monophyletic as currently delimited. However, if Chloraeinae and Pterostylidinae are excluded from Diurideae, the remaining subtribes form a well-supported, monophyletic group that is sister to a "spiranthid" clade. Chloraea, Gavilea, and Megastylis pro parte (Chloraeinae) are all placed among the spiranthid orchids and form a grade with Pterostylis… 
Molecular phylogenetic analyses of Drakaeinae: Diurideae (Orchidaceae) based on DNA sequences of the internal transcribed spacer region
TLDR
Results of the analysis of rDNA sequences supported the monophyly of the Drakaeinae orchid subtribe, with weak support for the inclusion of Spiculaea, and revealed six strongly supported monophyletic, well defined morphological groups.
Phylogenetic analysis of Chloraeinae (Orchidaceae) based on plastid and nuclear DNA sequences
TLDR
The phylogenetic relationships of subtribe Chloraeinae, a group of terrestrial orchids endemic to southern South America, have not been satisfactorily investigated, and analysis of nucleotide sequences from nuclear ribosomal internal transcribed spacer and plastid DNA suggests a relatively recent diversification of this group.
Phylogenetic relationships in Pterostylidinae (Cranichideae: Orchidaceae): combined evidence from nuclear ribomsomal and plastid DNA sequences
TLDR
Results revealed that none of the presently proposed classification systems for Pterostylidinae truly accounts for the underlying phylogenetic signal, and a streamlined classification system seems warranted, although further research based on a larger plastid DNA dataset is required to elucidate relationships in Clade C.
Molecular phylogenetics of Prescottiinae s.l. and their close allies (Orchidaceae, Cranichideae) inferred from plastid and nuclear ribosomal DNA sequences.
TLDR
A study on neotropical, terrestrial, orchidoid taxa of Prescottiinae s.l. (8 genera, ∼100 species), which are adapted to some of the highest elevation habitats on earth that support orchids, and indicates that the classification of Cranichideae needs to be reexamined.
Phylogenetics of Cranichideae with emphasis on Spiranthinae (Orchidaceae, Orchidoideae): evidence from plastid and nuclear DNA sequences.
TLDR
Morphological characters, especially those that have been used for taxonomic delimitation in Cranichideae, are discussed against the framework of the molecular trees, emphasizing putative synapomorphies and problems derived from lack of information or inadequate interpretation of the characters.
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.
Phylogenetic relationships in Pleurothallidinae (Orchidaceae): combined evidence from nuclear and plastid DNA sequences.
TLDR
There is strong support in most analyses for the monophyly of Pleurothallidinae and in some for inclusion of Dilomilis and Neocognauxia of Laeliinae, and most genera in the nine clades identified in the analyses are monophyletic.
Phylogeny of South American Pogonieae (Orchidaceae, Vanilloideae) based on sequences of nuclear ribosomal (ITS) and chloroplast (psaB, rbcL, rps16, and trnL-F) DNA, with emphasis on Cleistes and discussion of biogeographic implications
TLDR
Phylogenetic inferences within Cleistes and among genera of tribe Pogonieae were made based on nrDNA (ITS) and cpDNA (trnL-F, rps16, rbcL, and psaB) sequence data and maximum parsimony, and evidence indicates that Cleiste is paraphyletic.
Phylogenetic analysis of the subtribe Chloraeinae (Orchidaceae): a preliminary approach based on three chloroplast markers
TLDR
A more exhaustive taxonomic sampling is needed to resolve the systematic placement of the subtribe Chloraeinae and the internal relationships between the genera and species that form it.
Phylogenetic relationships of Discyphus scopulariae (Orchidaceae, Cranichideae) inferred from plastid and nuclear DNA sequences: evidence supporting recognition of a new subtribe, Discyphinae
TLDR
The authors' analyses failed to support inclusion of Discyphus in Spiranthinae, signifying instead that this genus represents an additional isolated lineage of “core spiranthids,” and would support the hypothesis that DiscyPHus represents a relict from an early radiation that also gave rise to Cranichidinae and Spiranthinee.

Phylogenetics of Asphodelaceae (Asparagales): An Analysis of Plastid rbcL and trnL-F DNA Sequences
TLDR
Phylogenetic relationships of Asphodelaceae were investigated by parsimony analysis of 57 monocotrbcL nucleotide sequences, including 17 genera that have at some time been assigned to the family, finding characters that have been used to separate Alooideae as a distinct group are found in at least some members of Asaphodeloideae.
A phylogenetic analysis of the Orchidaceae: evidence from rbcL nucleotide.
TLDR
RbcL fails to provide strong support for the interrelationships of the subfamilies of the Orchidaceae, and the cladograms presented here should serve as a standard to which future morphological and molecular studies can be compared.
Phylogenetic Relationships within Zygophyllaceae Based on DNA Sequences of three Plastid Regions, with Special Emphasis on Zygophylloideae
Abstract Parsimony analysis of nucleotide sequences of the plastid gene rbcL and non-coding trnL-F region was used to examine phylogenetic relationships of 36 members of Zygophyllaceae, especially of
What does morphology tell us about orchid relationships?--a cladistic.
TLDR
A cladistic analysis of Orchidaceae was undertaken for 98 genera using 71 morphological apomorphies based on a reconsideration of previous character analyses and newly discovered variation, revealing significant amount of structure and most traditionally recognized subfamilies are supported as monophyletic.
A phylogenetic analysis of the Orchidaceae
TLDR
The cladogram was used to develop a classification and a natural key to the tribes of the Orchidaceae, and the phylogeny and classification presented here are hypotheses of relationship and are therefore subject to change as more information becomes available.
Combining Data in Phylogenetic Systematics: An Empirical Approach Using Three Molecular Data Sets in the Solanaceae
TLDR
Data from sequences of two chloroplast DNA genes, ndhV and rbcL, and from restriction site mapping studies of the entire chloroplane genome were analyzed for the same set of 17 species of Solanaceae and the outgroup Ipomoea, finding the "X = 12" dade is the most well-supported dade within the family.
Character analysis of the seed coat in Spiranthoideae and Orchidoideae, with special reference to the Diurideae (Orchidaceae)
TLDR
Using quantitative descriptors of size and shape, it is demonstrated that some of the existing seed classes do not represent well delimited, discrete entities, and proposed new seed classes to meet these criteria are proposed.
THE MYCORRHIZAL RELATIONSHIPS OF AUSTRALIAN ORCHIDS
SUMMARY The symbiotic associations of Australian orchids have been examined by isolating Rhizoctonia endophytes from orchids growing in the field and by symbiotic germination of orchid seed. Many
MatK DNA Sequences and Phylogenetic Reconstruction in Saxifragaceae s. str
Comparative DNA sequencing of matK, a maturase coding gene located within the intron of the chloroplast gene trnK, was evaluated for phylogenetic utility using genera of Saxi- fragaceae s. str. The
The use of chloroplast DNA to resolve plant phylogenies: noncoding versus rbcL sequences.
TLDR
P pairwise comparisons among dicots and monocots for rbcL and two noncoding sequences of cpDNA show that these regions evolve faster (more than three times faster, on average) than rBCL, and that the trnL intron evolves at a rate that is the same as that of the intergenic spacer.
