Floristic composition and state of conservation of the threatened plants in Cajatambo / Lima / Peru were studied. The plants were collected at altitudes that ranged between 2 802 and 4 534 masl, in nine plant formations. A total number of 64 families, 211 genera and 355 species were reported, being Asteraceae, Poaceae, Fabaceae, Caryophyllaceae, Lamiaceae and Solanaceae the families best represented, and the genera with the highest number of species were Senecio, Baccharis, Calceolaria, Oxalis and Solanum. It was found out that 31 species belong to some category of threat. Some species are present only in a place such as Ocopata, Iscu-Viconga, Hualylashtoclanca and San Cristobal hill. The plant formations with higher presence of threatened species were: scrubland, agricultural field, grassland and Polylepis forest.

Keywords : floristic composition; plant formation; degree of threat.
