ILPIN Notes: Fernald et al. quoting Palziel indicates that seeds are used for porridge during scarcity in Africa. Species is found in southern U.S. and California. There is only one collection in Illinois in St. Claire county and this is probably extinct now. This is the only Illinois species. The exposed rachis tips of the spikes distinguish this from other digitate species. This species has spicate, digitate, and sided inflorescence branches. Species roots at culm nodes.
