Sarracenia alata, also known as yellow trumpets, [1] pale pitcher plant or pale trumpet, is a carnivorous plant in the genus Sarracenia . Specifically, S. alata is an endemic species to North America; it is native to the southeastern regions of the United States, including parts of the Gulf Coast states.
Like all Sarracenia species, S. alata is endemic to the New World, having evolved its perennial growth habit and insect-supplementation as a result of its unique ecological niche and environment. These pitcher plants grow in generally flat and low-lying areas, preferring protection from heavy breezes and high winds. They thrive where most plants would likely perish—in consistently saturated soils that are generally low in nutrients—as well as open wetlands, typically classified as longleaf pine ( Pinus palustris ) savannas.
The pale pitcher plant's habitat is split into two geographically separate areas: an eastern range from East Louisiana across the Gulf Coastline of Mississippi, and into West Alabama. The species also has a western range from East Texas into West Louisiana. [1] In Mississippi, there are mature, wild specimens of S. alata which rival the sheer size of any other Sarracenia species.
Among members of Sarracenia the floral coloring of Sarracenia alata is remarkably varied. Flowers may be cream to white, greenish, yellow or reddish. As the floral color variations exist within populations hundreds of miles from any other Sarracenia species, these variations cannot be attributed to hybridization. [2] Other than the range of floral colors, Sarracenia alata differs little from Sarracenia rubra . The veining of Sarracenia rubra pitchers tends to be more reticulated whereas that of Sarracenia alata often exhibits more of a pinstripe pattern and grows taller pitchers.
Pitcher plants are several different carnivorous plants that have modified leaves known as pitfall traps—a prey-trapping mechanism featuring a deep cavity filled with digestive liquid. The traps of what are considered to be "true" pitcher plants are formed by specialized leaves. The plants attract and drown their prey with nectar.
Sarracenia is a genus comprising 8 to 11 species of North American pitcher plants, commonly called trumpet pitchers. The genus belongs to the family Sarraceniaceae, which also contain the closely allied genera Darlingtonia and Heliamphora.
Darlingtonia californica, also called the California pitcher plant, cobra lily, or cobra plant, is a species of carnivorous plant. It is the sole member of the genus Darlingtonia in the family Sarraceniaceae. This pitcher plant is native to Northern California and Oregon, US, growing in bogs and seeps with cold running water usually on serpentine soils. This plant is designated as uncommon due to its rarity in the field.
Flatwoods, pineywoods, pine savannas and longleaf pine-wiregrass ecosystem are terms that refer to an ecological community in the southeastern coastal plain of North America. Flatwoods are an ecosystem maintained by wildfire or prescribed fire and are dominated by longleaf pine, and slash pine in the tree canopy and saw palmetto, gallberry and other flammable evergreen shrubs in the understory, along with a high diversity of herb species. It was once one of the dominant ecosystem types of southeastern North America. Although grasses and pines are characteristic of this system, the precise composition changes from west to east, that is, from Texas to Florida. In Louisiana, savannas even differ between the east and west side of the Mississippi River. The key factor maintaining this habitat type is recurring fire. Without fire, the habitat is eventually invaded by other species of woody plants.
Sarracenia flava, the yellow pitcherplant, is a carnivorous plant in the family Sarraceniaceae. Like all the Sarraceniaceae, it is native to the New World. Its range extends from southern Alabama, through Florida and Georgia, to the coastal plains of southern Virginia, North Carolina and South Carolina. Populations also exist in the Piedmont, Mendocino County, California and mountains of North Carolina.
Sarracenia purpurea, the purple pitcher plant, northern pitcher plant, turtle socks, or side-saddle flower, is a carnivorous plant in the family Sarraceniaceae.
Nepenthes alata is a tropical pitcher plant endemic to the Philippines. Like all pitcher plants, it is carnivorous and uses its nectar to attract insects that drown in the pitcher and are digested by the plant. It is highly polymorphic, and its taxonomy continues to be subject to revisions.
Nepenthes eustachya is a tropical pitcher plant endemic to Sumatra, where it grows from sea level to an elevation of 1600 m. The specific epithet eustachya, formed from the Greek words eu (true) and stachys (spike), refers to the racemose structure of the inflorescence.
Sarracenia rubra, also known as the sweet or purple pitcher plant, is a carnivorous plant in the genus Sarracenia. Like all Sarracenia, it is native to the New World. Its range extends from southern Mississippi, through southern Alabama, the Florida panhandle and Georgia, to the coastal plains of North Carolina and South Carolina.
Sarracenia oreophila, also known as the green pitcherplant, is a carnivorous plant in the genus Sarracenia. It has highly modified leaves in the form of pitchers that act as pitfall traps for prey. The narrow pitcher leaves are tapered tubes that rise up to 75 centimetres (30 in) from the ground, with a mouth 6 to 10 centimetres in circumference Like all the Sarracenia, it is native to North America. Sarracenia oreophila is the most endangered of all Sarracenia species, its range limited to a handful of sites in northern Alabama, North Carolina, Georgia, and—historically—Tennessee.
Sarracenia leucophylla, also known as the crimson pitcherplant, purple trumpet-leaf or white pitcherplant, is a carnivorous plant in the genus Sarracenia.
Sarracenia minor, also known as the hooded pitcherplant, is a perennial, terrestrial, rhizomatous, herbaceous, carnivorous plant in the genus Sarracenia. Like all the Sarracenia, it is native to North America.
Sarracenia rosea is a species of pitcher plant in the genus Sarracenia and is sometimes known as Burk's southern pitcher plant.
Carnivorous plants are plants that derive some or most of their nutrients from trapping and consuming animals or protozoans, typically insects and other arthropods, and occasionally small mammals and birds. They still generate all of their energy from photosynthesis. They have adapted to grow in places where the soil is thin or poor in nutrients, especially nitrogen, such as acidic bogs. They can be found on all continents except Antarctica, as well as many Pacific islands. In 1875, Charles Darwin published Insectivorous Plants, the first treatise to recognize the significance of carnivory in plants, describing years of painstaking research.
Sarracenia alabamensis, also known as the cane-brake pitcher plant, is a carnivorous plant in the genus Sarracenia. Like all Sarracenia, it is native to the New World. S. alabamensis subsp. alabamensis is found only in central Alabama, while subsp. wherryi is found in southwestern Alabama, eastern Mississippi and Florida. It is sometimes treated as two subspecies of S. rubra.
Exyra semicrocea, the pitcher plant mining moth, is a moth of the family Noctuidae. It is found from Northern North Carolina south to Florida west to Texas.
Nepenthes hamiguitanensis is a tropical pitcher plant endemic to a single peak on the Philippine island of Mindanao, where it grows at elevations of 1200–1600 m above sea level. Once thought to be a natural hybrid between N. micramphora and N. peltata, this plant is now considered a species of possible hybridogenic origin. It produces squat upper pitchers that vary greatly in pigmentation, from red speckled to yellow throughout.
Nepenthes viridis is a tropical pitcher plant endemic to the Philippines. It is known only from coastal areas at low altitude and has been recorded from Dinagat, Samar, and a number of surrounding islets. It is closely allied to the N. alata group of species.
Sarracenia jonesii is a species of pitcher plant endemic to seepage bogs in the appalachian mountains of North Carolina and South Carolina. It is currently only found in ten locations: 4 in North Carolina and 6 in South Carolina. S. jonesii is listed as endangered by the US federal government.
The North American continent is home to a wide variety of carnivorous plant species. Species from seven genera are native to the continent, and three of these genera are found nowhere else on the planet.
