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. [1]

This perennial grass grows up to a meter tall, [2] growing in clumps up to a meter wide. [3] 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. [2]

The specific epithet pauciflora, referring the Latin term for 'few flowered'. [4] [5]

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. [3]

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. [1]

Everglades National Park is an American national park that protects the southern twenty percent of the original Everglades in Florida. The park is the largest tropical wilderness in the United States and the largest wilderness of any kind east of the Mississippi River. An average of one million people visit the park each year. Everglades is the third-largest national park in the contiguous United States after Death Valley and Yellowstone. UNESCO declared the Everglades & Dry Tortugas Biosphere Reserve in 1976 and listed the park as a World Heritage Site in 1979, and the Ramsar Convention included the park on its list of Wetlands of International Importance in 1987. Everglades is one of only three locations in the world to appear on all three lists.

It also erects a thin stem which is topped with an inflorescence of one to three nodding flowers. Each flower is a shade of pink or purple to white, with two curving outer petals flexed back against the flower, and inner petals extended straight outward. The fruit is a capsule just over a centimeter long. The specific epithet pauciflora, refers to the Latin term for 'few flowered'.
