HYDRANGEA SECTION CORNIDIA: towards an evolutionary tree

August 2009 until December 2013, research project and PhD thesis

In the Neotropics, Hydrangea is represented by root-climbing species belonging to the poorly known section Cornidia. Field and herbarium observations show a yet unknown number of new, already threatened species of this group. For instance, in Mexico, where our work is most advanced, we are currently describing a surprisingly high number of new species (three were known before we started with our work), the majority of which we consider as Critically Endangered according to the IUCN Red List categories and criteria.

The majority of the American species occur at higher altitudes in pristine primary forest, in order of importance: montane cloud forest, temperate forest, or rainforest. Few species grow in secondary forest. Most species are micro-endemic and restricted to a specific mountain range; only some species have a wider distribution. General population sizes are small and in many localities limited to only a few individuals. Their current distribution is potentially a relic of an ancient more common occurrence, as most localities with more or less viable populations are remote and sometimes difficult to reach.
