Vesalea floribunda

collecting in Mexico

Mexico is one of the 18 megadiverse countries of the world. With over 200,000 different species, Mexico is home of 10–12% of the world's biodiversity. Mexico is crossed from north to south by two mountain ranges known as Sierra Madre Oriental and Sierra Madre Occidental, which are the extension of the Rocky Mountains from northern North America. From east to west at the center, the country is crossed by the Trans-Mexican Volcanic Belt also known as the Sierra Nevada. A fourth mountain range, the Sierra Madre del Sur, runs from Michoacán to Oaxaca.

The Caprifoliaceae of Mexico form an unusual disjunct phytogeographical link with the Flora of Eastern Asia where they are highly diverse. We were particularly interested in collecting samples from the genus Vesalea and Lonicera from which we made 16 collections. DNA material was also collected which will allow to study the phytogeography of these genera.See:

We made some important collections like Vesalea coriacea which was last collected in 1954 by Rzedowski, J. and thought to be extinct as well as a new record of V. grandifolia var. grandifolia in San Luis Potosi.
