Mac Alford, Ph.D.

Associate Professor, Department of Biological Sciences

Plant systematics and floristics are the two major areas of my research. In systematics, my research focuses on the tropical relatives of willows, poplars, and cottonwoods (Salicaceae and Samydaceae), trees and shrubs formerly placed in the heterogeneous family Flacourtiaceae. Delimiting and describing species, working out the nomenclature, and mapping distributions make up the classical aspects of these studies, and inferring relationships using phylogenetic techniques with data obtained from morphology, phytochemistry, anatomy, and DNA sequences make up the modern aspects.

In floristics, my research focuses on the state of Mississippi and the southeastern coastal plain. Mississippi currently lacks a manual, taxonomic keys, and county-level distribution maps of the known species of plants, and only recently has an electronic checklist of the species become available. Several students have worked on species delimitation problems in the southeast, in particular, applying genetic data to understanding whether a "complex" consists of one or more species.

Students are welcome in both of these areas of research. Local floras, species complexes in both the southeastern U.S. and the tropics, and classical and modern taxonomic questions are topics ready for pursuit.

I am also curator of the USM Herbarium. The collection presently consists of about 30,000 specimens and is an invaluable resource for research on the flora of Mississippi.
