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.
Digitaria is a genus of plants in the grass family native to tropical and warm temperate regions but can occur in tropical, subtropical, and cooler temperate regions as well. Common names include crabgrass, finger-grass, and fonio. They are slender monocotyledonous annual and perennial lawn, pasture, and forage plants; some are often considered lawn pests. Digitus is the Latin word for "finger", and they are distinguished by the long, finger-like inflorescences they produce.
Clematis pauciflora is a species of clematis known by the common name ropevine. This flowering plant is native to the high desert and chaparral slopes of southern California and Baja California. It is a woody vine with nodes every few centimeters which produce leaves and flowers. The leaves are made up of several dark green lobed leaflets, each one to three centimeters wide. From each leaf-bearing node grows an inflorescence of one to three flowers with narrow petallike sepals in shades of light yellow. Most of the flower is made up of a spray of up to 50 stamens and almost as many similar-looking pistils. The fruit is an achene equipped with a long plume-like style. The specific epithet pauciflora is Latin for 'few-flowered'.
Dicentra pauciflora is a species of flowering plant in Dicentra, the genus containing the bleeding-hearts. Its common names include shorthorn steer's head and few-flowered bleeding-heart. This perennial wildflower is native to the US states of Oregon and California, where it grows high in the mountains in gravelly soils. This is a short bleeding-heart, approaching 10 centimeters in maximum height. From a rhizome beneath the soil it extends several erect petioles, each holding a leaf divided into leaflets which are each divided into smooth, fingerlike lobes. 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'.
