Background: Myco-heterotrophy evolved independently several times during angiosperm evolution. Although many species of myco-heterotrophic plants are highly endemic and longdistance dispersal seems unlikely, some genera are widely dispersed and have pantropical distributions, often with large disjunctions. Traditionally this has been interpreted as evidence for an old age of these taxa. However, due to their scarcity and highly reduced plastid genomes our understanding about the evolutionary histories of the angiosperm myco-heterotrophic groups is poor. Results: We provide a hypothesis for the diversification of the myco-heterotrophic family Burmanniaceae. Phylogenetic inference, combined with biogeographical analyses, molecular divergence time estimates,... |

Four new species, one with two subspecies, of the genus Campylospermum are described, all endemic or sub-endemic to Gabon. These are C. auriculatum, C. gabonensis, C. gabonensis subsp. australis, C. glaucifolium and C. occidentalis. Distribution maps and scans of the holotypes are provided as well as preliminary IUCN Red List assessments. New combinations for nine species formerly assigned to the genus Ouratea and/or Gomphia are proposed: C. andongensis, C. glomeratum, C. longestipulatum, C. lunzuensis, C. lutambensis, C. nutans, C. plicatum and C. warneckei. Finally, one taxon is raised from the variety to species level, leading to the new combination C. costatum. |
