|discussion=<p>Steinchisma is a genus of 5-6 species that grow in moist or wet, usually open, sandy areas in warm-temperate and tropical regions of the Western Hemisphere. A single species is native the Flora region. It is sometimes included in Panicum, but recent studies support its recognition as a separate genus. Photosynthesis in Steinchisma is intermediate between C3 and C4 plants.</p>
