Catasetum krahlii (Orchidaceae, Catasetinae): a new and threatened species from the Brazilian Amazon

In the present study we propose a new Catasetum taxon belonging to the group of species with symmetrical and converging antennae. It was found in a vegetation of “terra firme” and “campinarana” in the central Brazilian Amazon. A detailed description of the taxon is given as well as a photograph plate and comments relating to distribution, habitat, phenology and conservation status. It is compared to C. rivularium and C. barbatum which are sympatric species and somewhat similar to the new taxon. Furthermore, we present a key to Catasetum species with symmetrical and convergent antennae occurring in the Brazilian Amazon.

期刊介绍： Experimental, theoretical and applied papers on all aspects of plant (including algae) and fungi biology are welcome. The submitted manuscript or its essential content must not have been published previously or be under consideration for publication elsewhere. Contributions should be substantial, written in high-quality English and show general interest. We expect that the submitted manuscript presents a great novelty in Botany, and this should attract a wide audience. Considering this, case studies are only considered if the narrative and implications are provided to be of general interest. Thus, manuscripts that report aspects of local interest are discouraged unless the implications of the findings are wide-reaching. Manuscripts with agronomic subjects are expected to contain a substantial amount of basic plant biology. Please see below some details for specific area.
