Xyris straminea is a small annual tufted species of plant in the Xyridaceae family. It can be found in seasonally wet soils and inselbergs in Tropical Africa.
Linear leaves, sometimes rugulose at the base and weakly curved towards the apex. Inflorescence, mostly ovoid or ellipsoid spikes distinguished by the presence of ovate pale brown bracts, between 4.5 - 6.5 mm. [1] [2]
Widespread in Tropical West Africa where it often grows on wet rocky slopes, rock pools and a few other seasonally wet habitats. [1]
The Poales are a large order of flowering plants in the monocotyledons, and includes families of plants such as the grasses, bromeliads, rushes and sedges. Sixteen plant families are currently recognized by botanists to be part of Poales.
The tropics are the regions of Earth surrounding the Equator. They are defined in latitude by the Tropic of Cancer in the Northern Hemisphere at 23°26′10.4″ (or 23.43623°) N and the Tropic of Capricorn in the Southern Hemisphere at 23°26′10.4″ (or 23.43623°) S. The tropics are also referred to as the tropical zone and the torrid zone.
Tropical and subtropical moist broadleaf forests (TSMF), also known as tropical moist forest, is a subtropical and tropical forest habitat type defined by the World Wide Fund for Nature.
Tropical climate is the first of the five major climate groups in the Köppen climate classification identified with the letter A. Tropical climates are defined by a monthly average temperature of 18 °C (64.4 °F) or higher in the coolest month, and feature hot temperatures all year-round. Annual precipitation is often abundant in tropical climates, and shows a seasonal rhythm but may have seasonal dryness to varying degrees. There are normally only two seasons in tropical climates, a wet season and a dry season. The annual temperature range in tropical climates is normally very small. Sunlight is intense in these climates.
The Xyridaceae are a family of flowering plants. This family has been recognized by many taxonomists and is known as the yellow-eyed grass family.
Xyris is a genus of flowering plants, the yelloweyed grasses, in the yellow-eyed-grass family. The genus counts over 250 species, widespread over much of the world, with the center of distribution in the Guianas.
Xyris andina is a species of plant in the Xyridaceae family. It is endemic to Ecuador. Its natural habitat is subtropical or tropical moist montane forests, and much of its range now under threat of habitat destruction.
Andina, meaning Andean, may refer to:
Anna Amelia Mauve was a South African botanist who worked at the Botanical Research Institute in Pretoria. She catalogued more than 4,000 plant specimens from the Kalahari and Soutpansberg regions. She made major contributions to the journals Flowering Plants of Africa and Bothalia.
Xyris tennesseensis is a rare species of flowering plant in the family Xyridaceae known by the common name Tennessee yellow-eyed grass. It is native to a small section of the Southeastern United States, including parts of the states of Alabama, Georgia, and Tennessee. A federally listed endangered species, it is threatened by the loss and degradation of its habitat.
Xyris complanata, known as the feathered yellow-eye is a tufted herb in the Xyridaceae family. It is native to southern China, India, Sri Lanka, Thailand, Cambodia, Laos, Vietnam, Malaysia, Indonesia, the Philippines, New Guinea and Australia. It is also naturalized in Hawaii where it is known as Hawai'i yelloweyed grass. In New South Wales it grows in moist areas, often near swamps or in heathland.
Xyris ambigua, the coastal plain yelloweyed grass, is a North American species of flowering plant in the yellow-eyed-grass family. It is native to southern and eastern Mexico, Central America, Cuba, and the southeastern and south-central United States.
Xyris baldwiniana, common name Baldwin's yelloweyed grass, is a North American species of flowering plant in the yellow-eyed-grass family. It is native to southern Mexico (Chiapas), Central America, and the southeastern and south-central United States.
Xyris elliottii, common name Elliott's yelloweyed grass, is a North American species of flowering plant in the yellow-eyed-grass family. It is native to the coastal plain of the United States from Mississippi to South Carolina plus southern Mexico (Tabasco), Central America and the West Indies.
Xyris jupicai, common name Richard's yelloweyed grass, is a New World species of flowering plants in the yellow-eyed-grass family. It is widespread in North America, South America, Mesoamerica, and the West Indies.
Xyris smalliana, Small's yelloweyed grass, is a North American species of flowering plants in the yellow-eyed-grass family. It grows on the coastal plain of the eastern and southern United States from Maine to Texas, as well as in Cuba, Central America, and the State of Tabasco in southern Mexico.
Seasonal tropical forest, also known as moist deciduous, semi-evergreen seasonal, tropical mixed or monsoon forests, typically contain a range of tree species: only some of which drop some or all of their leaves during the dry season. This tropical forest is classified under the Walter system as (i) tropical climate with high overall rainfall and (ii) having a very distinct wet season with dry season. These forests represent a range of habitats influenced by monsoon (Am) or tropical wet savannah (Aw) climates. Drier forests in the Aw climate zone are typically deciduous and placed in the Tropical dry forest biome: with further transitional zones (ecotones) of savannah woodland then tropical and subtropical grasslands, savannas, and shrublands.
Xyris gracilis, commonly known as slender yellow-eye, is a species of flowering plant in the family Xyridaceae and is endemic to eastern Australia. It is a tufted herb with linear leaves with 5 to 8 flowering stems with bright yellow flowers.
Xyris marginata, commonly known as alpine yellow eye, was first collected by German-Australian botanist Ferdinand von Mueller in 1875. Xyris marginata is a monocot in the family Xyridaceae which is endemic to King Island (Tasmania) and Tasmania, commonly growing in button grass moorlands, at altitudes of up to 1070 meters (3,510.5 ft) above sea level.
