Phemeranthus rugospermus is a species of flowering plant in the miner's lettuce family, Montiaceae, known by the common names prairie fameflower, rough-seeded fameflower, and flower-of-an-hour. It is native to the central United States from Texas and Louisiana north to Nebraska, Minnesota, and Wisconsin. [2] [3]
Claytonia perfoliata, also known as Indian lettuce, spring beauty, winter purslane, or miner's lettuce, is a flowering plant in the Montiaceae family. It is a fleshy, herbaceous annual plant native to the western mountain and coastal regions from southernmost Alaska and central British Columbia all the way south to Central America, but most common in California in the Sacramento and northern San Joaquin Valleys.
Montiaceae are a family of flowering plants, comprising about 14 genera with about 230 known species, ranging from herbaceous plants to shrubs. The family has a cosmopolitan distribution.
Texas is the second largest state in the United States by both area and population. Geographically located in the South Central region of the country, Texas shares borders with the U.S. states of Louisiana to the east, Arkansas to the northeast, Oklahoma to the north, New Mexico to the west, and the Mexican states of Chihuahua, Coahuila, Nuevo León, and Tamaulipas to the southwest, while the Gulf of Mexico is to the southeast.
Phemeranthus rugospermus is a perennial herb growing up to 25 centimeters (10 inches) tall with an erect branching or unbranched stem. The cylindrical leaves are up to 6 centimeters (2.4 inches) long. The pink flowers arise on a tall stalk. The capsules contain wrinkly seeds. [4] The flowers open for one day, and only in the afternoon. [2]
Phemeranthus rugospermus grows in open habitat where there is little competition from other plants, such as rock outcrops, stretches of sand, or open woods. It can be found on dunes along the banks of the Mississippi River. It benefits from low levels of disturbance, such as fires. [2] Human-caused forms of disturbance, such as off-road vehicle activity, can be beneficial at times. [3] Other plants in the habitat may include Andropogon scoparius , Selaginella rupestris , Opuntia compressa , Panicum virgatum , Allium stellatum , Isanthus brachiatus , Houstonia longifolia , and Ambrosia artemisiifolia . [2]
In physical geography, a dune is a hill of loose sand built by aeolian processes (wind) or the flow of water. Dunes occur in different shapes and sizes, formed by interaction with the flow of air or water. Most kinds of dunes are longer on the stoss (upflow) side, where the sand is pushed up the dune, and have a shorter "slip face" in the lee side. The valley or trough between dunes is called a slack. A "dune field" or erg is an area covered by extensive dunes.
The Mississippi River is the second-longest river and chief river of the second-largest drainage system on the North American continent, second only to the Hudson Bay drainage system. Its source is Lake Itasca in northern Minnesota and it flows generally south for 2,320 miles (3,730 km) to the Mississippi River Delta in the Gulf of Mexico. With its many tributaries, the Mississippi's watershed drains all or parts of 32 U.S. states and two Canadian provinces between the Rocky and Appalachian mountains. The main stem is entirely within the United States; the total drainage basin is 1,151,000 sq mi (2,980,000 km2), of which only about one percent is in Canada. The Mississippi ranks as the fourth-longest and fifteenth-largest river by discharge in the world. The river either borders or passes through the states of Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana.
An off-road vehicle is considered to be any type of vehicle which is capable of driving on and off paved or gravel surface. It is generally characterized by having large tires with deep, open treads, a flexible suspension, or even caterpillar tracks. Other vehicles that do not travel public streets or highways are generally termed off-highway vehicles, including tractors, forklifts, cranes, backhoes, bulldozers, and golf carts.
