A briological team composed by María J. Cano, and Juan A. Jiménez from University of Murcia (Spain) carried out an expedition to Northern Peru (Cajamarca, Lambayeque, Piura, Trujillo) in June of 2009. This trip was funded by Spanish Ministry of Education and Science through the project “Study of the tribes Barbuleae and Bryoerythrophylleae (Pottiaceae, Bryophyta) in South America” (CGL2007-60692).
This exploration was carried out thanks to the cooperation of Asunción Cano of University San Marcos of Lima (USM). We wish to acknowledge the assistance of Segundo Leiva and Mario Zapata (Universidad Privada Antenor Orrego). About 550 specimens of bryophytes were collected, keeping at MUB with duplicates at USM.
