Digitaria pauciflora
''Digitaria pauciflora'' is a species of grass known by the common names twospike crabgrass, Florida pineland crabgrass, Everglades grass, few-flowered fingergrass, and particular grass. It is endemic to Florida in the United States, where it is found only in the Everglades.〔(''Digitaria pauciflora''. ) The Nature Conservancy.〕
This perennial grass grows up to a meter tall,〔(''Digitaria pauciflora''. ) Grass Manual Treatment.〕 growing in clumps up to a meter wide.〔(''Digitaria pauciflora''. ) Center for Plant Conservation.〕 The densely hairy leaves are up to 12 centimeters long. The inflorescence is a panicle with 2 or 3 branches up to 11 centimeters long.〔
Today this plant only occurs in Everglades National Park in rocky pinelands habitat and prairie. This type of habitat can flood during the wet season. It is also prone to wildfire. Associated plants include ''Pinus elliottii'' var. ''densa'', ''Sabal palmetto'', ''Schizachyrium rhizomatum'', ''Vernonia blodgettii'', and ''Elytraria caroliniensis'' var. ''angustifolia''.〔
The total distribution is about 31 square miles. It is represented by a single population. While the population is largely protected within the Everglades, the surrounding landscape is undergoing rapid development. Within the park the species may be affected by changes in the local hydrology and the fire regime and the invasion of non-native plants.〔
