The Integrated Taxonomic Information System (ITIS) is an American partnership of federal agencies designed to provide consistent and reliable information on the taxonomy of biological species. ITIS was originally formed in 1996 as an interagency group within the US federal government, involving several US federal agencies, and has now become an international body, with Canadian and Mexican government agencies participating. The database draws from a large community of taxonomic experts. Primary content staff are housed at the Smithsonian National Museum of Natural History and IT services are provided by a US Geological Survey facility in Denver. The primary focus of ITIS is North American species, but many biological groups exist worldwide and ITIS collaborates with other agencies to increase its global coverage.
Oenothera is a genus of about 145 species of herbaceous flowering plants native to the Americas. It is the type genus of the family Onagraceae. Common names include evening primrose, suncups, and sundrops. They are not closely related to the true primroses.
The Onagraceae are a family of flowering plants known as the willowherb family or evening primrose family. They include about 650 species of herbs, shrubs, and trees in 17 genera. The family is widespread, occurring on every continent from boreal to tropical regions.
Pseudacris is a genus of frogs in the family Hylidae found in North America ranging from the Pacific coastline to the Atlantic.
Oenothera lindheimeri, formerly Gaura lindheimeri, and commonly known as Lindheimer's beeblossom, white gaura, pink gaura, Lindheimer's clockweed, and Indian feather, is a species of Oenothera.
Oenothera curtiflora, known as velvetweed, velvety gaura, downy gaura, or smallflower gaura, is a species of flowering plant native to the central United States and northern Mexico, from Nebraska and Wyoming south to Durango and Nuevo Leon.
Gaura is a genus of flowering plants in the family Onagraceae, native to North America. The genus includes many species known commonly as beeblossoms. Recent genetic research has shown that the genus is paraphyletic unless the monotypic genus Stenosiphon is included within Gaura, increasing the number of species in the genus to 22.
Homopus is a genus of tiny tortoises in the family Testudinidae, endemic to southern Africa. Three species have been moved to the genus Chersobius.
Oenothera fruticosa, the narrowleaf evening primrose or narrow-leaved sundrops, is a species of flowering plant in the evening primrose family.
Oenothera suffrutescens is a species of flowering plant in the evening primrose family known as scarlet beeblossom and scarlet gaura.
Oenothera xenogaura, is a species of flowering plant in the evening primrose family known by the common names Drummond's beeblossom and scented gaura. It is native to Mexico and its range extends into Texas. It can be found in parts of the southern and southwestern United States where it is an introduced species and is a minor weed in some areas. This is a mat-forming perennial herb growing from rhizomes. Stems reach 10 or 12 centimeters in height can be plentiful and tightly clumped. Leaves are about one to nine centimeters long and linear to slightly oval-shaped. The stems and foliage are covered in hairs. The plant produces small spike inflorescences with centimeter-long sepals and smaller spoon-shaped petals which are white, fading to pink. The fruit is an erect, woody capsule about a centimeter long with a base shaped like a stalk with a bulge at the center.
Gaura sinuata is a species of flowering plant in the evening primrose family known by the common names wavyleaf beeblossom and Red River gaura. In 2007 the species, along with the genus Gaura was reclassified in the genus Oenothera. This species then becomes O. sinuosa in Oenothera Section Gaura.
Asarina is a flowering plant genus of only one species, Asarina procumbens, the trailing snapdragon, which is native to southern Europe. Originally placed in the Scrophulariaceae, the genus has more recently been moved to the Plantaginaceae. Species from North America formerly placed in the genus Asarina are now placed in Holmgrenanthe, Lophospermum, Mabrya and Maurandya, as well as Neogaerrhinum. Asarina is now regarded as exclusively an Old World genus.
Oenothera harringtonii is a species of flowering plant in the evening primrose family known by the common names Arkansas Valley evening primrose and Colorado Springs evening primrose. It is endemic to the state of Colorado in the United States.
Oenothera guara, formerly known as Gaura biennis, the biennial gaura or biennial beeblossom, is a North American flowering plant that can reach 6 ft (1.8 m) in height at maturity. Its upper half is made up of flowering stems, which are covered with soft, white hairs. It has light pink colored flowers, which turn a vibrant red/pink color in the late summer to early fall seasons. These colors make this plant attractive to butterflies and bees, and are in full bloom just before many fall plant species begin to bloom.
Macrobdella is a genus of leeches native to freshwater ecosystems of North America, especially Canada, Mexico, and the United States. The genus is commonly referred to as North American medicinal leeches.
Euphorbia discoidalis, commonly known as summer spurge, is a flowering plant. A dicot, it grows across parts of the southern United States. It reaches about 18 inches (460 mm) in height and has white flowers in the late summer and early fall. It is part of the Euphorbiaceae (spurge) family and the genus Euphorbia.
Oenothera suffulta, known as roadside gaura, honeysuckle gaura, or kisses, is a flowering plant in the primrose family, Onagraceae. It is endemic to the United States, in Texas and southern Oklahoma.
