Resolving relationships in an exceedingly young Neotropical orchid lineage using Genotyping-by-sequencing data
(2020-03-01)
Poor morphological and molecular differentiation in recently diversified lineages is a widespread phenomenon in plants. Phylogenetic relationships within such species complexes are often difficult to resolve because of the ...
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 ...
The stained-glass palm, geonoma epetiolata
(2007-09)
Geonoma epetiolata is the only neotropical palm that exhibits substantial leaf mottling. This article provides a summary of its biology and conservation, some observations of natural populations and a discussion of the ...
Two new endemic species of Monstera (Araceae: Monsteroideae: Monstereae) from Golfito in southern Costa Rica
(2020)
Monstera croatii M.Cedeño & A.Hay and M. gambensis M.Cedeño & M.A.Blanco (Araceae: Monsteroideae: Monstereae) are newly described and illustrated from cantón Golfito in the Pacific lowlands of southern Costa Rica. Notes ...
A new species and a new record of Malaxis (Malaxidinae) from Costa Rica
(2022-04-25)
We describe and illustrate a new species and a new record of Malaxis from the lower montane and montane forests of Costa Rica. Taxonomic descriptions, illustrations, distribution maps, and conservation assessments are ...
New records of Araceae for Costa Rica and Panama
(2020-05)
Four species are documented for the first time for the Costa Rican flora: Anthurium curvispadix, Anthurium palosecense, Monstera integrifolia, Monstera spruceana. Two species are first documented for the Panamanian flora: ...
Pseudocopulatory pollination in Lepanthes (Orchidaceae: Pleurothallidinae) by fungus gnats
(2005-04)
Background and Aims: Lepanthes is one of the largest angiosperm genera (>800 species). Their non-rewarding, tiny and colourful flowers are structurally complex. Their pollination mechanism has hitherto remained unknown, ...
A taxonomic revision of Monstera Adans. (Araceae: Monsteroideae) in Costa Rica
(2022-01-31)
Monstera Adans. (Araceae: Monstereae) is revised for Costa Rica. Thirty-five species are recognised, of which one (M. deliciosa) is introduced. Of them, ten have been only very recently described and Monstera tablasensis ...
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 ...
A reexamination of Monstera oreophila Madison (Araceae: Monsteroideae) and description of two new pinkish-spathed species of Monstera from Costa Rica and Panama
(2021)
Monstera gentryi from Panama and M. mittermeieri from Costa Rica are newly described, illustrated and compared with M. oreophila. The differences between the novelties and similar species are presented and an amended ...
