Comments: Starved rosette panic grass is a perennial grass common on open dry, sandy soils throughout the State of New Jersey.  It is often observed as a roadside species.  It is often found with other common dry roadside associates such as Danthonia spicata, Dichanthelium dichotomum, Dichanthelium spherocarpon and Panicum virgatum.  The species narrow basal leaves masks the rosette panic grass affiliation.  Our specimens show a wide degree of variation with many specimens showing fruiting culms longer than basal leaves.  This is somewhat dissimilar to the descriptions provided by FNA and Fernald (1950).  The acuminate spikelet and other common characters separate this species from its closest relative, Dichanthelium linearifolium.
