ARTETA, María et al. Vascular plants from the bay of Juli, Titicaca Lake, Puno-Peru. Ecol. apl. [online]. 2006, vol.5, n.1-2, pp.29-36. ISSN 1726-2216.

The vascular plant species richness is presented for the bay of Juli, specifically the Huaquina sector and the communities of Olla and C’aje-Huaylluni, on the Titicaca Lake shore. This area was studied from March to May 2006, covering altitudinal ranges of 3830 up to 4200 masl. Drying, mounting and determination of the collected samples were performed at the Herbarium Arequipense (HUSA) of the Universidad Nacional de San Agustín de Arequipa. A total of 185 species were found, belonging to the divisions: Pteridophyta, Pinophyta and Magnoliophyta and can be grouped into 58 families and 137 genera; Asteraceae and Poaceae families had most of the species among Magnoliophyta; within Petridophyta, Pteridaceae and Dryopteridaceae presented the highest percentages. Only 3 species were found in Pinophyta. The richest sector was Huaquina, where 136 species could be found. A very striking fact is that 25.4 % (47 spp.) of the species were new records for the Puno department.
