Abstract:—We provide the first record of Puya yakespala for Bolivia, a species previously believed to be endemic to Argentina. We present information on its morphology, phenology, floral visitors, habitat, and distribution. The rosette plant with an inflorescence is up to 3.5 m long and has lemon-yellow colored flowers and contains black nectar. Its flowering phase lasts for approximately five months. It is found in the xerophytic Puna habitat within two national and one municipal protected area. We documented symbiotic relationships between P. yakespala and eight bird species that consume its nectar, the hummingbird Oreotrochilus estella being the most frequent visitor. Given its restricted distribution in Argentina and Bolivia, we suggest conducting additional research on its role in community ecology.
