DNA barcoding the floras of biodiversity hotspots
TLDR
Analysis of >1,000 species of Mesoamerican orchids, DNA barcoding with matK alone reveals cryptic species and proves useful in identifying species listed in Convention on International Trade of Endangered Species (CITES) appendixes.
Phylogenetics of Stelis and closely related genera (Orchidaceae: Pleurothallidinae)
TLDR
A new phylogenetic analysis of Stelis and closely related genera based on DNA sequences from nuclear ITS and chloroplast matK, based on a much larger sample, is presented; it includes more than 100 species assigned to StelIS and covers all proposed groupings within the genus, many of which have not previously been represented.
Convergent evolution of floral signals underlies the success of Neotropical orchids
TLDR
It is proposed that a system of multifarious floral mimicry—a form of Batesian mimicry that involves multiple models and is more complex than a simple one model–one mimic system—operates in certain food-deceptive Oncidiinae orchids and rewarding species of Malpighiaceae.
The Orchidaceae of Ruiz & Pavón's "Flora Peruviana et Chilensis": a taxonomic study. I
Inspired by King Carlos III in the second half of 18th Century, the Spanish government demonstrated a serious interest in the study of the rich floras of the colonies of the New World. The Royal
An updated checklist of the Orchidaceae of Panama
TLDR
This checklist contains 1365 species (including two natural hybrids and three subspecies) in four subfamilies, 16 tribes, 27 subtribes and 187 genera and is an important initial step toward the development of an illustrated treatment of the Orchidaceae of Panama.
CONTRIBUTIONS TOWARD A REASSESSMENT OF COSTA RICAN ZYGOPETALINAE (ORCHIDACEAE). 3. A SYSTEMATIC REVISION OF DICHAEA IN COSTA RICA
TLDR
A systematic revision of the genus Dichaea (Orchidaceae) in Costa Rica is presented and a new species, D. gomezlauritoi, is described and illustrated from the wet Caribbean plains of central Costa Rica.
Molecular phylogenetics and the evolution of fruit and leaf morphology of Dichaea (Orchidaceae: Zygopetalinae).
TLDR
Results indicate that section Dichaeopsis is polyphyletic and based on symplesiomorphies, including deciduous leaves and smooth ovaries that are widespread in Zygopetalinae.
GENERIC RELATIONSHIPS OF ZYGOPETALINAE (ORCHIDACEAE: CYMBIDIEAE): COMBINED MOLECULAR EVIDENCE
TLDR
The phylogenetic relationships of the orchid subtribe Zygopetalinae were evaluated using parsimony analyses of combined DNA sequence data of nuclear ITS 1 and 2 and of the trnL-F intergenic spacer and the plastid matK .
