Evolutionary Trees and Numerical Taxonomy in Studies of Tillandsia (Bromeliaceae)
Bromeliaceae, a tropical american plant family has received two major monographic treatments in the past half century and several smaller, partial treatments in recent years. The goals of this study were to ascertain the interresemblances and probable evolutionary pathways among the nine subgenera of Tillandia and Vriesea; to conduct the same types of analyses using the 36 species of the subgenus Phytarrhiza centered in upland South America; to interrelate the pleistocene climatic changes and the evolution of the mesic and xeric species in order to help unravel the mystery of the origin of the mesic and xeric forms of bromeliads.
