Schizachyrium Nees. Subfamily: Panicoideae. Tribe: Andropogoneae. Subtribe: Andropogoninae. supertribe: Andropogonodae. clade: "PACMAD". Common name: Little Bluestem.
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.

- Please include your name and if possible, email in case when need to clarify what you wrote.
- If you opt out of including email, please be as specific as possible (e.g., which photo is incorrect?)
- Please do not submit questions asking to identify plants or about horticultural topics (e.g., how do I control an invasive plant in my garden?). Instead, those questions can be submitted here for the Carolinas region only.
- Please do not send us feedback about unkeyed species as this work is ongoing.
- Please allow time for flora edits to show in our next data release. We greatly appreciate your feedback but may require extra time to research complicated taxonomic issues.
