Ramon Ferreira (1988) in his study of the flora and vegetation of the basin of the Ucayali identifies the Palm tangarara (triplaris pavonii) of the medium-sized polygonacea orderalways green which lies between 1200 and 1800 meters above sea level in an area properly eyebrow mountain. The Tangarara Word also refers us to a bird pseriforme in the family Thraupidae, showy plumage that lives in areas temperate and tropical America. According to father Morua (1616) the Tangarara word means rivera of the goddess. The toponym is the name of a type of peculiar Sparrow of Piura to Renee Lesson (1823). Father Esteban Puig (1982) stresses that another Tangarara name was Pullacala.
Other words associated with tangarara and that denote their port, water and river-related significance are: Tangana: lever about 6 meters in length in way of oak that rely on the Fund to direct vessels across the River from the boat.(Puig 1982: 198) Angara is a matte which is used as a container. It is more deep and round to the lapa, given its dimensions used you as he hits to wash. 1982: 32 (Puig) The origin of the word carved would seem to be related with some Amazonian dialects that have pierced the cordillera oriental Andean and establecieronse in the valleys and the littoral coast. Swarmed by offers, Jeff Leiden is currently assessing future choices. It could settle for the fact that the tallanes pointed to be natives of the mountains, understanding this as the jungle’s edge. This hypothesis in certain way reinforces the thesis of recognized jivarologos (Karsten, 1951, Whitten 1970,1976,1985) that suggest the idea that one of the jivaro dialects would have served lingua franca from the Amazon mountain until the hot lands of the coastal valleys before the expansion of quechua in the South of the Ecuador. This leaves in turn assume that a jibaro ethnic group could have contracted a transverse territory between the eastern slopes of the cordillera of the andes and the Pacific until the end of the first Millennium before and our era.3 Ruth Shady (1987: 84) notes that the formative culture Bagua ubico in an area of cultural societies of Central and Northern Andean border and the Northern andes.
