Anatomy, Morphology, and Cladistic Analysis of Monsonia L. (Geraniaceae).
Phylogenetip relationships among the 25 species of the old-world genus Monsonia are explored by means of a cladistic analysis. After a detailed revision, 20 morphological and anatomical characters were selected, including some new ones from nectaries, androecium, and mericarps. Phylogenetic analysis...
