Itincludes a taxonomic history, discussion of morphological characters,key, full synonymies with typifications, descriptions, specimen citations (and an index to numbered collections), figures of a leaf,flower, capitulum, and capitulescence of each species, and distributionmaps of the more abundant species. Two species are endemic, while twoothers are known only from Guatemala and southern Mexico. One, mainlyof temperate North American distribution (M.scandens) occurs in extremenortheastern Mexico, while another (M.amblyolepis), primarily ofColombia annd Panama, is present as a disjunct in Chiapas.
