Tripsacum australe (H.C.Cutler & E.S.Anderson, 1941) | |
Tripsacum australe is a species of grass in the family Poaceae. It is a perennial or rhizomatous geophyte which grows primarily in the wet tropical biome and is endemic to South America. Some common Spanish names for this species, according to Universidad Nacional de Columbia, include 'arroz silvestre', 'cañarote', and 'gramalote'. [1]
T. australe is native to Bolivia, North Brazil, Central-West Brazil, Colombia, French Guiana, Guyana, Paraguay, Peru, Suriname, Trinidad-Tobago, and Venezuela. [2]
The two known varieties [3] of T. australe are diploid (2n = 36). Both varieties can cross and produce fertile hybrids with each other. These two varieties have also been crossed with Tripsacum dactyloides var. meridonale (2n = 36) these hybrids are partially sterile. [4]
The varieties are:
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera. Hybrids are not always intermediates between their parents such as in blending inheritance, but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are.
Larches are deciduous conifers in the genus Larix, of the family Pinaceae. Growing from 20 to 45 metres tall, they are native to the cooler regions of the northern hemisphere, where they are found in lowland forests in the high latitudes, and high in mountains further south. Larches are among the dominant plants in the boreal forests of Siberia and Canada. Although they are conifers, larches are deciduous trees that lose their needles in the autumn.
Quercus stellata, the post oak or iron oak, is a North American species of oak in the white oak section. It is a slow-growing oak that lives in dry areas on the edges of fields, tops of ridges, and also grows in poor soils, and is resistant to rot, fire, and drought. Interbreeding occurs among white oaks, thus many hybrid species combinations occur. It is identifiable by the rounded cross-like shape formed by the leaf lobes and hairy underside of the leaves.
Salix × fragilis, with the common names crack willow and brittle willow, is a hybrid species of willow native to Europe and Western Asia. It is native to riparian habitats, usually found growing beside rivers and streams, and in marshes and water meadow channels. It is a hybrid between Salix euxina and Salix alba, and is very variable, with forms linking both parents.
Mentha aquatica is a perennial flowering plant in the mint family, Lamiaceae. It grows in moist places and is native to much of Europe, northwest Africa and southwest Asia.
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.
Loricariidae is the largest family of catfish, with over 90 genera and just over 680 species. Loricariids originate from freshwater habitats of Costa Rica, Panama, and tropical and subtropical South America. These fish are noted for the bony plates covering their bodies and their suckermouths. Several genera are sold as "plecos", notably the suckermouth catfish, Hypostomus plecostomus, and are popular as aquarium fish.
Fuchsia magellanica – commonly known as the hummingbird fuchsia, hardy fuchsia or chilco – is a species of flowering plant in the evening primrose family Onagraceae, native to the lower Southern Cone of southern South America.
Iris giganticaerulea, the giant blue iris, is a species of iris, in the subgenus Limniris, in the series Hexagonae. It is a rhizomatous perennial, from northern America. It has long bright green leaves, very tall stems and one or two musky fragrant flowers in a range of blue shades or rarely white.
Vaccinium arboreum is a species of Vaccinium native to the southeastern and south-central United States, from southern Virginia west to southeastern Nebraska, south to Florida and eastern Texas, and north to Illinois.
The Caribbean pine is a hard pine species native to Central America and the northern West Indies. It belongs to subsection Australes in subgenus Pinus. It inhabits tropical and subtropical coniferous forests such as Bahamian pineyards, in both lowland savannas and montane forests.
Iris × germanica is the accepted name for a species of flowering plants in the family Iridaceae commonly known as the bearded iris or the German bearded iris. It is one of a group of hybrid origin. Varieties include I. × g. var. florentina.
Epidendrum secundum, one of the crucifix orchids, is a poorly understood reed stemmed species, which Dressler (1989) describes as "the Epidendrum secundum complex." According to Dressler, there are dozens of varieties, some of which appear to deserve species rank. Arditti and Ghani note that E. secundum has the distinction of bearing the longest seeds known in the Orchidaceae, 6.0 mm long. By comparison, the seeds of E. ibaguense are only 2.9 mm long.
Tripsacum dactyloides, commonly called eastern gamagrass, or Fakahatchee grass, is a warm-season, sod-forming bunch grass. It is widespread in the Western Hemisphere, native from the eastern United States to northern South America. Its natural habitat is in sunny moist areas, such as along watercourses and in wet prairies. In some areas, it has adapted well to disturbed conditions.
Psilocybe hoogshagenii is a species of psilocybin mushroom in the family Hymenogastraceae. The mushroom has a brownish conical or bell-shaped cap up to 3 cm (1.2 in) wide that has an extended papilla up to 4 mm long. The stem is slender and 5 to 9 cm long. The variety P. hoogshagenii var. convexa lacks the long papilla.
Symphyotrichum lanceolatum is a species of flowering plant in the family Asteraceae native to North America. Common names include panicled aster, lance-leaved aster, and white panicled aster. It is a perennial, herbaceous plant that may reach 1.5 meters tall or more, sometimes approaching 2 m. The lance-shaped leaves are generally hairless but may feel slightly rough to the touch on the top because of tiny bristles. S. lanceolatum blooms July to October. The flowers grow in clusters and branch in panicles. They have 16–50 white ray florets that are up to 14 millimeters long and sometimes tinged pink or purple. The flower centers consist of disk florets that begin as yellow and become purple as they mature.
Iris setosa, the bristle-pointed iris, is a species of flowering plant in the genus Iris of the family Iridaceae, it belongs the subgenus Limniris and the series Tripetalae. It is a rhizomatous perennial from a wide range across the Arctic sea, including Alaska, Maine, Canada, Russia, northeastern Asia, China, Korea and southwards to Japan. The plant has tall branching stems, mid green leaves and violet, purple-blue, violet-blue, blue, to lavender flowers. There are also plants with pink and white flowers.
Iris fulva, also known as copper iris, is a species in the genus Iris, it is also in the subgenus Limniris and in the series Hexagonae. It is a rhizomatous perennial, endemic to the southern and central United States. It has copper-red to deep red flowers and bright green leaves.
Citrus taxonomy is the botanical classification of the species, varieties, cultivars, and graft hybrids within the genus Citrus and related genera, found in cultivation and in the wild.
Tripsacum lanceolatum is a species of grass with the common name of Mexican gamagrass, though as with many common names it doesn't accurately describe it fully since it grows far outside Mexico as well. T. lanceolatum is a perennial bunchgrass as most species in its genus are, that grows in a Tropical Dry biome. Considered LC by IUCN.
