Abstract Detail



Solving taxonomic puzzles in Hyobanche (Orobanchaceae).

Hyobanche (Orobanchaceae) is a small holoparasitic genus endemic to southern Africa. Species delimitation has been difficult due to the nature of how herbarium specimens appear – brown or black masses of stuck together flowers. Populations of Hyobanche observed in the field have considerable morphological variation (flower color and size, inflorescence shape, pattern of sepal fusion, etc), which is consistent within a geographic region. These observations were the motivation for conducting morphological and molecular analyses to determine whether the current taxonomy is a correct representation of species diversity in the genus. A morphometric analysis of ca 400 herbarium accessions, including all type specimens, was conducted and compared to previously reported results from AFLP marker studies. These results support a revision of Hyobanche to encompass two morphologically distinct sections (Sanguinea and Rubra), several new species, and synonymization for the Hyobanche rubra complex.
