Abstract
Pakayaku is a scarcely contacted community of Kichwa indigenous people situated in the banks of river Bobonaza (Pastaza, Ecuador) at the heart of the Ecuadorian Amazonia. In this paper we present a catalogue of 250 taxa of useful vascular plants belonging to 81 families from the Pakayaku ancestral territories, a so far unexplored area. 126 taxa are first citations for the Bobonaza valley, 22 new for Pastaza province, the largest administrative province of the country, and 1, Pouteria manaosensis, is cited for the first time for Ecuador. In total, approximately 60% of the catalogue consists of new citations.
