Distribution of North American grasses within the subfamily Chloridodeae.

In the 1950’s, Hartley showed that tribes of Poaceae have distinct geographic patterns. In 2000, Barkworth and Capels compared the geographical distribution of grass tribes within North America using the Manual of Grasses of North America classification. They showed that the two large tribes of Chloridoid grasses, Cynodonteae and Eragrosteae, had different but overlapping distributions. In 2010, Peterson et al published a new tribal treatment for the Chloridoideae based on phylogenetic analysis. To better understand how these changes in circumscription impacted patterns of distribution in North America within the subfamily Chloridodeae, I analyzed data from Symbiota to compare the distribution of grasses of the subfamilies tribes. In addition, the data were used to analyze and compare environmental characteristics of the tribes.
