During a revisionary study ofSpigelia, three new species from Mexico were discovered. Two of these new species appear to be narrow endemics, one in the state of Chiapas and one in the state of Guerrero, and the third is more widespread in Mexico and Guatemala. These new species are described, illustrated, and distinguished from other North AmericanSpigelias.

A phylogenetic parsimony and Bayesian analysis of ITS sequences from 15 Spigelia species plus 17 outgroups in Loganiaceae confirms its independent taxonomic status: on the basis of sequence similarity and phylogenetic topology it is phylogenetically distinct from all Spigilia species sequenced so far.

Morphological Diversity and Taxonomic Importance of Fruits and Seeds of the Genus Spigelia (Loganiaceae) in Mexico

The fruits and seeds of the Mexican Spigelia species proved to be taxonomically useful, allowing the differentiation of four main clusters of species separated by the size of the analyzed structures in the three analyses.

CLADISTICS AND FAMILY LEVEL CLASSIFICATION OF THE GENTIANALES

Cl cladistic results are presented that show Loganiaceae, sensu lato, to be a paraphyletic group definable only by plesiomorphies, with members showing closest relationships to other families of the Gentianales.
