The taxonomy ofOreosparte(Apocynaceae: Asclepiadoideae)
2013
Oreosparte is a monotypic genus described as bearing strong similarities to Hoya (Marsdenieae), but separated from it based on the presence of a campanulate corolla with a contracted throat and lanceolate, spreading lobes. Its type specimen was destroyed during the fire at the Berlin herbarium in 1943. So far no suitable lectotype or further specimens belonging to the taxon were located. We report the finding of one specimen of Oreosparte collected from the type locality, allowing the selection of a neotype, to provide an extended description, and discussion of the morphological affinities with Hoya. Based on its morphology, despite being probably closely related to Hoya, we suggest that Or…
Nomenclatural changes in Apteranthes Mikan (Asclepiadoideae, Apocynaceae)
2006
El género Apteranthes Mikan se considera constituido por unos ocho táxones, en su mayoría distribuidos por el norte de África. Sin embargo, algunos de sus componentes han sido infravalorados en las revisiones más recientes del género, pese a estar bien caracterizados morfológica y biogeográficamente. En la presente contribución, se aportan datos que sirven para justificar la propuesta de dos nuevas combinaciones nomenclaturales: Apteranthes europaea subsp. negevensis (Zohari ex Feinbrun) M.B. Crespo –que incluye las poblaciones orientales de la especie–, y A. munbyana subsp. hispanica (Coincy) M.B. Crespo & Mateo –que se aplica las poblaciones del sudeste ibérico–. Para ambas se adjuntan ic…
First records of pollinators of two co-occurring Mediterranean Apocynaceae
2011
This article presents results of a field survey of pollinators of two Apocynaceae, Periploca laevigata subsp. angustifolia (Labill.)Markgraf (Periplocoideae) and Caralluma europaea (Guss.) N.E.Br. Asclepiadoideae) co-occurring on Lampedusa Island, Mediterranean sea. Fifteen species within nine families of Diptera have been identified as pollinators of the two plants. The families involved are Tephritidae, Milichiidae, Trixoscelididae, cathophagidae, Anthomyiidae, Muscidae, Calliphoridae, Sarcophagidae, Rhinophoridae. Families of Muscidae and Sarcophagidae are the more represented, respectively with four and three species. P. laevigata subsp. angustifolia seems to have a broader spectrum of …
