Data from: Generic and subtribal relationships in Neotropical Cymbidieae (Orchidaceae) based on matK/ycf1 plastid data
Relationships among all subtribes of Neotropical Cymbidieae (Orchidaceae) were estimated using combined matK/ycf1 plastid sequence data for 289 taxa. The matrix was analyzed using RAxML. Bootstrap (BS) analyses yield 100% BS support for all subtribes except Stanhopeinae (87%). Generic relationships within subtribes are highly resolved and are generally congruent with those presented in previous studies and as summarized in Genera Orchidacearum. Relationships among subtribes are largely unresolved. The Szlachetko generic classification of Maxillariinae is not supported. A new combination is made for Maxillaria cacaoensis J.T.Atwood in Camaridium.
Data from: Molecular phylogenetics of Maxillaria and related genera (Orchidaceae: Cymbidieae) based on combined molecular data sets
The orchid genus Maxillaria is one of the largest and most common of neotropical orchid genera, but its current generic boundaries and relationships have long been regarded as artificial. Phylogenetic relationships within subtribe Maxillariinae sensu Dressler (1993) with emphasis on Maxillaria s.l. were inferred using parsimony analyses of individual and combined DNA sequence data. We analyzed a combined matrix of nrITS DNA, the plastid matK gene and flanking trnK intron, and the plastid atpB-rbcL intergenic spacer for 619 individuals representing ca. 354 species. The plastid rpoC1 gene (ca. 2600 bp) was sequenced for 84 selected species and combined in a more limited analysis with the other data sets to provide greater resolution. In a well-resolved, supported consensus, most clades were present in more than one individual analysis. All the currently recognized minor genera of "core" Maxillariinae (Anthosiphon, Chrysocycnis, Cryptocentrum, Cyrtidiorchis, Mormolyca, Pityphyllum, and Trigonidium) are embedded within a polyphyletic Maxillaria s.l. Our results support the recognition of a more restricted Maxillaria, of some previously published segregate genera (Brasiliorchis, Camaridium, Christensonella, Heterotaxis, Ornithidium, Sauvetrea), and of several novel clades at the generic level. These revised monophyletic generic concepts should minimize further nomenclatural changes, encourage monographic studies, and facilitate more focused analyses of character evolution within Maxillariinae.

FIGURE 3. Phylogenetic relationships of C. densiflorum based on the nuclear DNA (ITS). The three numbers near the nodes are Bayesian posterior probabilities (PP), maximum parsimony bootstrap percentages (BP MP), and maximum likelihood bootstrap percentages (BP ML). "*" indicates that the node is 100% or 1.00 supported. "-" indicates that the node is incongruent between the topology of the Bayesian tree and the MP/ML trees.
