Baileya (the desert marigolds) is a genus of plants in the aster family Asteraceae. All are native to the southwestern United States and to Mexico.
Asteraceae or Compositae is a very large and widespread family of flowering plants (Angiospermae).
The Southwestern United States, also known as the American Southwest, is the informal name for a region of the western United States. Definitions of the region's boundaries vary a great deal and have never been standardized, though many boundaries have been proposed. For example, one definition includes the stretch from the Mojave Desert in California to Carlsbad, New Mexico, and from the Mexico–United States border to the southern areas of Colorado, Utah, and Nevada. The largest metropolitan areas are centered around Phoenix, Las Vegas, Tucson, Albuquerque, and El Paso. Those five metropolitan areas have an estimated total population of more than 9.6 million as of 2017, with nearly 60 percent of them living in the two Arizona cities—Phoenix and Tucson.
Mexico, officially the United Mexican States, is a country in the southern portion of North America. It is bordered to the north by the United States; to the south and west by the Pacific Ocean; to the southeast by Guatemala, Belize, and the Caribbean Sea; and to the east by the Gulf of Mexico. Covering almost 2,000,000 square kilometres (770,000 sq mi), the nation is the fifth largest country in the Americas by total area and the 13th largest independent state in the world. With an estimated population of over 120 million people, the country is the eleventh most populous state and the most populous Spanish-speaking state in the world, while being the second most populous nation in Latin America after Brazil. Mexico is a federation comprising 31 states and Mexico City, a special federal entity that is also the capital city and its most populous city. Other metropolises in the state include Guadalajara, Monterrey, Puebla, Toluca, Tijuana and León.
They are typically annual, though B. multiradiata may be perennial. The leaves, which may range from being entire to deeply lobed, mostly occur in a basal cluster. From this arises several flower stems, up to 18 inches (50 cm) in height, usually carrying a single yellow radiate flower each, although B. pauciradiata may have 2-3 flowers on a stem.
Desert marigolds typically have their main bloom in the spring, extending through July. Summer thunderstorms may enable a second bloom in October and even into November.
A thunderstorm, also known as an electrical storm or a lightning storm, is a storm characterized by the presence of lightning and its acoustic effect on the Earth's atmosphere, known as thunder. Relatively weak thunderstorms are sometimes called thundershowers. Thunderstorms occur in a type of cloud known as a cumulonimbus. They are usually accompanied by strong winds, heavy rain, and sometimes snow, sleet, hail, or, in contrast, no precipitation at all. Thunderstorms may line up in a series or become a rainband, known as a squall line. Strong or severe thunderstorms include some of the most dangerous weather phenomena, including large hail, strong winds, and tornadoes. Some of the most persistent severe thunderstorms, known as supercells, rotate as do cyclones. While most thunderstorms move with the mean wind flow through the layer of the troposphere that they occupy, vertical wind shear sometimes causes a deviation in their course at a right angle to the wind shear direction.
Baileya species are used as food plants by the larvae of some Lepidoptera species including Schinia miniana (which feeds exclusively on the genus) and Schinia pallicincta (which feeds exclusively on B. pauciradiata).
A larva is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle.
Lepidoptera is an order of insects that includes butterflies and moths. About 180,000 species of the Lepidoptera are described, in 126 families and 46 superfamilies, 10 per cent of the total described species of living organisms. It is one of the most widespread and widely recognizable insect orders in the world. The Lepidoptera show many variations of the basic body structure that have evolved to gain advantages in lifestyle and distribution. Recent estimates suggest the order may have more species than earlier thought, and is among the four most speciose orders, along with the Hymenoptera, Diptera, and Coleoptera.
Schinia, commonly called flower moths, is a large genus of moths belonging to the family Noctuidae. The genus has a Holarctic distribution with the vast majority of species being found in North America, many with a very restricted range and larval food plant.
The genus is named after US microscopist and West Point professor Jacob Whitman Bailey (1811–1857), known for his studies of diatoms .
Jacob Whitman Bailey (1811–1857) was an American naturalist, known as the pioneer in microscopic research in America.
Gaillardia is a genus of flowering plants in the sunflower family, Asteraceae, native to North and South America. It was named after an M. Gaillard de Charentonneau, an 18th-century French magistrate who was a patron of botany. The common name may refer to the resemblance of the inflorescence to the brightly patterned blankets made by Native Americans, or to the ability of wild taxa to blanket the ground with colonies. Many cultivars have been bred for ornamental use.
