Key to Schizachyrium

A genus of about 60 species, widespread in tropical, subtropical, and warm temperate regions of the World. The issue of the separation of Schizachyrium from Andropogon, the membership of each genus, the morphological characters that are key and diagnostic (when characters are in conflict), and the reciprocal monophyly of each genus remain very uncertain (see, for instance, Arthan et al. 2017). For now, I retain the predominant usage of recent decades of separating the two genera, and allocate the species to genera on the pragmatic character of single racemes (Schizachyrium) vs. 2 or more racemes (Andropogon), but that may well prove erroneous.
