Collection trip: Perú, November-December 2007



Participants: Eric Tepe, Stephen Stern, Segundo Leiva, Mario Zapata, José Mateo, and María Paz Moreno

This five-week trip to Peru was focused on collecting Solanaceae on the eastern slopes of the Andes, one of the richest areas in the World for Solanum.  We were based in Lima at the Herbario Nacional (USM), and got a lot of help from the staff there.  The first week was spent in and around Oxapampa, where the Missouri Botanical Garden has a project and a regional herbarium (HOXA).  Collecting in this area was very fruitful, thanks to the help of José Mateo from HOXA.  We then spent a few days collecting near the coast and the high Andes, before heading North to the city of Trujillo.  The rest of the trip was spent with Segundo Leiva and Mario Zapata, from the Museo de Historia Natural at the Universidad Privada de Antenor Orrego (HAO).  Segundo is a Solanaceae specialist and his help was invaluable as we collected over the Andes and into the Amazon Basin.  Highlights from this part of the trip included the rarely collected S. angustialatum and S. chamaepolybotryon.
