Capillitial extrusion from fruits of Maxillaria nardoides (Orchidaceae: Maxillariinae)
(2006-09)
The fruits of Maxillaria nardoides are fusiform, 1–1.2 × 0.3 cm. Upon dehiscence, six valves separate completely at the apex, and a long cylindric mass (up to 6.5 cm long × 3 mm in diameter) of white hygroscopic trichomes ...
Phylogenetic systematics of subtribe Spiranthinae (Orchidaceae: Orchidoideae: Cranichideae) based on nuclear and plastid DNA sequences of a nearly complete generic sample
(2018)
Subtribe Spiranthinae is the most species-rich lineage of terrestrial Neotropical orchids, encompassing > 500 species and 40 genera. We conducted maximum parsimony and maximum likelihood phylogenetic analyses of DNA sequence ...
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 ...
Recircumscription of Pityphyllum (Orchidaceae: Maxillariinae)
(2006-03)
Based upon morphological and molecular evidence, Maxillaria huancabambae (Kraenzl.) C. Schweinf. and M. saragurensis Dodson are transferred to Pityphyllum Schltr. These and other species of Pityphyllum are illustrated with ...
A new Maxillaria (Orchidaceae) from Panama and Colombia, and a Brazilian species found in Ecuador.
(2007)
A new species from western Panama, Maxillaria curvicolumna M.A. Blanco & Neubig is described and illustrated. It is distinguished by its rhizomatous habit; small, ovoid pseudobulbs subtended by a pair of narrow leaves with ...
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 ...
