Taxonomy and Classification
This chapter provides a description of all plant families and genera that include putative fully mycoheterotrophic species, excluding initial and partial mycoheterotrophs. The overview covers a totalExpand

Phylogenetic relationships of the mycoheterotrophic genus Voyria and the implications for the biogeographic history of Gentianaceae.
PREMISE OF THE STUDY The angiosperm family Gentianaceae comprises over 1700 species in 91 genera. Gentianaceae are distributed worldwide, but most species occur in temperate zones. PhylogeneticExpand

Back to Gondwanaland: can ancient vicariance explain (some) Indian Ocean disjunct plant distributions?
Oceans, or other wide expanses of inhospitable environment, interrupt present day distributions of many plant groups. Using molecular dating techniques, generally incorporating fossil evidence, weExpand

Variation and evolution of herkogamy in Exochaenium (Gentianaceae): implications for the evolution of distyly.
BACKGROUNDS AND AIMS The spatial separation of stigmas and anthers (herkogamy) in flowering plants functions to reduce self-pollination and avoid interference between pollen dispersal and receipt.Expand

Ancestral and monophyletic presence of diplostigmaty in Sebaea (Gentianaceae) and its potential role as a morphological mixed mating strategy.
* Diplostigmaty, the presence of a primary (apical) stigma and secondary (mid-stylar) stigmas along the style, is only known from the genus Sebaea (Gentianaceae). Early work indicated that theExpand

The polyphyletic genus Sebaea (Gentianaceae): a step forward in understanding the morphological and karyological evolution of the Exaceae.
Within the Gentianaceae-Exaceae, the most species-rich genus Sebaea has received very little attention in terms of phylogenetic or karyological investigations. As a result, the exact number ofExpand

Taxonomy of Exochaenium and Lagenias: Two Resurrected Genera of Tribe Exaceae (Gentianaceae)
Abstract Morphological and molecular evidence has recently revealed the paraphyly of Sebaea (Gentianaceae: Exaceae), and support the establishment of three genera corresponding to highly supportedExpand

Klackenbergia (Gentianaceae-Exaceae), a new endemic genus from Madagascar
Several lines of evidence (morphological, karyological and molecular) support the exclusion of both Sebaea madagascariensis Klack. and S. condensata Klack. from Sebaea Sol. ex. R. Br. (Gentianaceae -Expand

Diplostigmaty in plants: a novel mechanism that provides reproductive assurance
Differentiation of female sexual organs in flowering plants is rare and contrasts with the wide range of male reproductive strategies. An unusual example involves diplostigmaty, the possession ofExpand

Cytogeography of Gentianaceae–Exaceae in Africa, with a special focus on Sebaea: the possible role of dysploidy and polyploidy in the evolution of the tribe
Unlike other tribes of Gentianaceae, Exaceae have so far received little attention regarding their karyological evolution. Indeed, only 35 chromosome number counts (19 species) have been referencedExpand
