Phylogenetic reassessment of Specklinia and its allied genera in the pleurothallidinae (Orchidaceae)
The phylogenetic relationships within Specklinia (Pleurothallidinae; Orchidaceae) and related genera are re-evaluated using Bayesian analyses of nrITS and chloroplast matK sequence data of a wide sampling of species. ...
Further disentangling of a taxonomic puzzle: Maxillaria Ramosa, Ornithidium Pendulum, and a new species, O. Elianae (Orchidaceae)
(Harvard Papers in Botany, 2008)
McIllmurray and Oakeley (2004) demonstrated that the name Maxillaria ramosa has been misapplied to Ornithidium pendulum since 1967, and possibly corresponds to M. cassapensis. We refer Ornithidium ochraceum, O. loefgrenii, ...
Lepanthes Sw. [with three new species from Costa Rica]
The genus Lepanthes in Costa Rica is presented and discussed. Three new species (Lepanthes sol Pupulin, L. victoria Pupulin & Bogarín, and L. marta-herraae Bogarín & Pupulin) are described and illustrated.
Lepanthes aures‐ursinae and L. vertebrata spp. nov. (Orchidaceae: Pleurothallidinae) from Panama
Panama is still far from completing its orchid flora inventories, where large genera such as Lepanthes (Pleurothallidinae) reveal novelties regularly. Here, we describe and illustrate two new species of Lepanthes. Lepanthes ...
Recent origin and rapid speciation of Neotropical orchids in the world's richest plant biodiversity hotspot
The Andean mountains of South America are the most species‐rich biodiversity hotspot worldwide with c. 15% of the world's plant species, in only 1% of the world's land surface. Orchids are a key element of the Andean flora, ...
Two novelties in genus Platystele (Orchidaceae: Pleurothallidinae) from Costa Rica
Two new species of Platystele allied to P. oxyglossa complex are described from Costa Rica. Platystele carl-lueriana can be distinguished from P. catiensis and P. oxyglossa by the compact inflorescence that barely exceeds ...
Masdevallia luerorum (Orchidaceae: Pleurothallidinae), a new species from Costa Rica
Masdevallia luerorum from the southern Pacific region of Costa Rica is described and illustrated. It resembles M. lata, but differs in the single flowered inflorescence, the shorter sepals, the broad and cylindrical sepaline ...
The glandulous Specklinia: morphological convergence versus phylogenetic divergence
The present paper focuses on the systematics of the Specklinia glandulosa species complex. Traditionally, S. glandulosa has been considered a widely distributed and variable species, ranging from Mexico to the guiana Shield. ...
Pollination of Habenaria tridactylites (Orchidaceae: Orchidinae) on the Canary Islands
We investigated the pollination of Habenaria tridactylites, an endemic orchid of the Canary Islands. The entirely green, widely open flowers have a long spur containing nectar. We carried out fieldwork, a molecular clock ...
