The taxonomy of the Ribes andicola group and Urtica is investigated for the relict forests in the AmotapeHuancabamba Zone and especially the relict forests of NW Peru. Three new species of Ribes are described, Ribes contumazensis as local endemic from Contumazá, R. colandina as widespread across the Andes from Lambayeque and La Libertad to Amazonas and R. sanchezii as endemic to forests overlooking the Marañon. Additionally, Ecuadoren R. austroecuadorense is recorded for the first time from Peru from forest relics in Huancabamba (Piura) and Chota (Cajamarca). Two new species of Urtica are described, U. urentivelutina as a local endemic on the slopes overlooking the Marañon near Chagual (La Libertad), and U. lalibertadensis which is widespread in La Libertad from Otuzco to Tayabamba. Urtica longispica is reported as new to the flora of Peru and U. macbridei is reported from northern Pe...

Fátima Cáceres de Baldarrago was a Peruvian botanist recognized for her knowledge of the Cactaceae family and the flora of southern Peru. She had an active interest in the different aspects of "Scientia amabilis". Thus, her concern to learn from scientific collections, and the management and review of various taxa led her to do internships at the Instituto Nacional de Innovación Agraria, La Joya, Arequipa, and at the Herbarium Truxillense of the Universidad Nacional de Trujillo, La Libertad, as well as in the Museo de Historia Natural de la Universidad Nacional Mayor de San Marcos, which she created a permanent collaborative connection.
