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 ...
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 influence of leaf characteristics on epiphyllic cover: A test of hypotheses with artificial leaves
(1995-12-31)
Studies of epiphyll ecology have been hindered by the biochemical and morphological variability of the leaf substrate. The use of artificial (plastic ribbon tape) leaves solved that problem in a study done at the Braulio ...
