The Flora del Río Cenepa, Amazonas, Peru covers an area of about 6100 km² in the department of Amazonas, in northern Peru close to the border with Ecuador. The Río Cenepa is a tributary of Río Marañon and its drainage extends from the Río Marañon to the border with Ecuador. The area is covered with lowland rainforest, with elevations ranging from 300 to 1050 m. The variation in substrates, from riverine deposits to nutrient-poor sandstone outcrops, has contributed greatly to the botanical diversity documented during the preparation of this work.

This flora consists of two volumes: Volume 1 contains an introduction and treatments of the Pteridophyta, Gymnospermae, and the families of flowering plants from Acanthaceae through Fabaceae. Volume 2 contains treatments of the families of flowering plants from Gentianaceae through Zingiberaceae.

The Introduction is written in two languages, Spanish and Aguaruna—the language of the indigenous people of the study area, and includes a general description of the area, sections on human population, land use, vegetation types, common names, conservation aspects, and a list of collaborators. In Volume 1, eight pages of color photos illustrate the habitat of the study area and representative species.

In Spanish. Two-volume set.
