Molecular phylogenetics of Maxillaria and related genera (Orchidaceae: Cymbidieae) based on combined molecular data sets
(2007-11)
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 ...

Preliminary molecular phylogenetics of Sobralia and relatives (Orchidaceae: Sobralieae)
(2011-12)
With over 200 species, the orchid tribe Sobralieae is a major constituent of the Neotropical flora. As currently circumscribed, the tribe includes four genera: Elleanthus, Epilyna, Sertifera, and Sobralia. Most
species ...
Generic recircumscriptions of Oncidiinae (Orchidaceae: Cymbidieae) based on maximum likelihood analysis of combined DNA datasets
(2012)
Phylogenetic relationships within the orchid subtribe Oncidiinae sensu Chase were inferred using maximum
likelihood analyses of single and multilocus DNA sequence data sets. Analyses included both nuclear ribosomal internal ...

Phylogenetic utility of ycf1 in orchids: a plastid gene more variable than matK
(2008-11-12)
Plastid DNA sequences have been widely used by systematists for reconstructing plant phylogenies. The
utility of any DNA region for phylogenetic analysis is determined by ease of amplification and sequencing, confidence ...
