shows great morphological variation in some characters, particularly the size of the leaves and the indumentum of leaves and stems. Despite few specimens analyzed and populations found in the wild, it is possible to see a continuum between the different morphotypes identified. The variations observed are attributed to different environmental conditions and should not intervene in the recognition of these populations as a single species.
