Abstract: Many negative factors are affecting the flora of the islands, which makes it necessary to analyse its capacity to survive and adapt to environmental changes.Studies on the productivity of Canary flora species are scarce. In this work, we have analysed the distribution and productivity of flowers and seeds of eleven species of the genus Echium spp. in Tenerife. Data on morphological characters were collected and correlated with reproductive effort. The analyses obtained indicate that there are significant differences between morphological and productivity characters for the different species, as well as forgrow thtype, with E.wildpretii being the species with the highest production. Significant differences in flower production etween localities were obtained for the same species in 66.6% of the taxa studied, indicating hatthe species change their production depending on the locality where they are found. However, the current distribution and abundance of this genus in Tenerife cannot be explained exclusively by their productivity; the anagement developed with some of the taxa and the anthropic influence also explain the proportion of potential area occupied.
