Digitaria pauciflora is a blue-green to gray bunch grass that forms mounds of up to one meter (three feet) in diameter. Much of what is known regarding Digitaria pauciflora is taxonomic in nature (e.g. Hitchcock 1935; Webster and Hatch 1990; Wunderlin 1998). It is generally agreed upon that this species is currently known only from the Everglades pinelands (with the exception of a single occurrence which has since disappeared in the Richmond Pineland Complex (Bradley and Gann 1999; R. Hammer pers. comm.) Digitaria pauciflora appears to be fire tolerant, existing in ecosystems that are known to have frequent fires (Avery 1983; Bradley and Gann 1999).
Distribution & Occurrence
This species is known from rocky pinelands (Hitchcock 1935; Wunderlin 1988) or more specifically the fingerglades or ecotone between pine rockland and marl prairie, and edges of each ecosystem. These habitats can flood, especially the marl prairie, each wet season (Bradley and Gann 1999; Avery 1983).
Associated species include: Pinus elliottii var. densa, Sabal palmetto, Schizachyrium rhizomatum, Vernonia blodgettii and Elytraria caroliniensis var. angustifolia.
