Cryptocentrum beckendorfii (Orchidaceae: Maxillariinae), an extraordinary newspecies from Andean Peru
Cryptocentrum beckendorfii is described and illustrated from a single cultivated plant reputedly from the Amazonian slopes in the Cuzco region of Andean Peru. This species is similar to C. pseudobulbosum, also from the Amazonian slopes of the Andes, with which it shares sympodial habit with pseudobulbs unlike most species of the genus, which are monopodial and lack pseudobulbs. It differs from ...
متن کاملThe pollination mechanism in Trigonidium obtusum Lindl (Orchidaceae: Maxillariinae): sexual mimicry and trap-flowers.
The pollination process in Trigonidium obtusum Lindl. (Epidendroideae: Maxillariinae) is documented. The flowers are pollinated by sexually excited drones of Plebeia droryana (Meliponinae). When attempting to copulate either with sepals or petals, these bees slip on the waxy perianth surface and become trapped in the funnel-like flower tube. Bees trying to escape from the flowers may instead ac...
متن کاملMolecular phylogeny of the neotropical genus Christensonella (Orchidaceae, Maxillariinae): species delimitation and insights into chromosome evolution.
BACKGROUND AND AIMS Species' boundaries applied within Christensonella have varied due to the continuous pattern of variation and mosaic distribution of diagnostic characters. The main goals of this study were to revise the species' delimitation and propose a more stable classification for this genus. In order to achieve these aims phylogenetic relationships were inferred using DNA sequence dat...
متن کاملFish utilisation of managed realignments
One area of ecological benefit not yet fully evaluated in European waters is the utilisation of restored saltmarsh habitats by fish species. This study examines the utilisation of managed realignments and relic saltmarsh by fish species. Factors affecting habitat heterogeneity and fish populations are discussed, and recommendations are made with respect to scheme design and management that will...
