This is one of the true prairie grasses. Because of its dense tufts of sprawling narrow leaves, there is really nothing else that closely resembles it. While some Sporobolus spp.
(Dropseeds) have narrow spike-like inflorescences that are often partially hidden by their sheaths, other species in this genus have long-exerted inflorescences that are airy and open. Prairie Dropseed is a good example of this latter group; it has longer spikelets than other species in this group.
