Morpho-geographical analysis of Veronica section Beccabunga.
Veronica section Beccabunga occurs primarily in the temperate regions of the land masses of the northern and southern hemispheres with the exception of Australia and New Zealand, where it is a rare introduction. Computer assisted techniques involving the General Similarity Coefficient of Gower, UPGM...
