Chaparral is a shrubland plant community found primarily in the U.S. state of California, in southern Oregon, and in the northern portion of the Baja California Peninsula in Mexico. It is shaped by a Mediterranean climate and infrequent, high-intensity crown fires, featuring summer-drought-tolerant plants with hard sclerophyllous evergreen leaves, as contrasted with the associated soft-leaved, drought-deciduous, scrub community of coastal sage scrub, found often on drier, southern facing slopes within the chaparral biome. Three other closely related chaparral shrubland systems occur in central Arizona, western Texas, and along the eastern side of central Mexico's mountain chains (mexical), all having summer rains in contrast to the Mediterranean climate of other chaparral formations. Chaparral comprises 9% of the California's wildland vegetation and contains 20% of its plant species. The name comes from the Spanish word for place of the scrub oak, chaparro.
The Malpighiales comprise one of the largest orders of flowering plants, containing about 36 families and more than 16,000 species, about 7.8% of the eudicots. The order is very diverse, containing plants as different as the willow, violet, poinsettia, manchineel, rafflesia and coca plant, and are hard to recognize except with molecular phylogenetic evidence. It is not part of any of the classification systems based only on plant morphology. Molecular clock calculations estimate the origin of stem group Malpighiales at around 100 million years ago (Mya) and the origin of crown group Malpighiales at about 90 Mya.
The Cyperaceae are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges. The family is large, with some 5,500 known species described in about 90 genera, the largest being the "true sedges" genus Carex with over 2,000 species.
The Big Bend is part of the Trans-Pecos region in southwestern Texas, United States along the border with Mexico, north of the prominent bend in the Rio Grande for which the region is named. Here the Rio Grande passes between the Chisos Mountains in Texas and the Sierra Madre Oriental in Mexico as it changes from running east-southeast to north-northeast. The region covers three counties: Presidio County to the west, Brewster County to the east, and Jeff Davis County to the north.
Cryolophosaurus is a genus of large theropods known from only a single species Cryolophosaurus ellioti, known from the early Jurassic period of Antarctica. It was about 6.5 metres (21.3 ft) long and 465 kilograms (1,025 lb) in weight, making it one of the largest theropods of its time. Individuals of this species may have grown even larger, because the only known specimen probably represents a sub-adult. Cryolophosaurus is known from a skull, a femur and other material, the skull and femur of which have caused its classification to vary greatly. The femur possesses many primitive characteristics that have classified Cryolophosaurus as a dilophosaurid or a neotheropod outside of Dilophosauridae and Averostra, whereas the skull has many advanced features, leading the genus to be considered a tetanuran, an abelisaurid, a ceratosaur and even an allosaurid. Since its original description, the consensus is that Cryolophosaurus is either a primitive member of the Tetanurae or a close relative of that group, most recently, it has been found to be a derived neotheropod, close to Averostra.
"What Is and What Should Never Be" is a song by English rock band Led Zeppelin. It was written by Jimmy Page and Robert Plant and was included as the second track on Led Zeppelin II (1969).
Malpighiaceae is a family of flowering plants in the order Malpighiales. It comprises about 73 genera and 1315 species, all of which are native to the tropics and subtropics. About 80% of the genera and 90% of the species occur in the New World and the rest in the Old World.
The Rafflesiaceae are a family of rare parasitic plants comprising 36 species in 3 genera found in the tropical forests of east and southeast Asia, including Rafflesia arnoldii, which has the largest flowers of all plants. The plants are endoparasites of vines in the genus Tetrastigma (Vitaceae) and lack stems, leaves, roots, and any photosynthetic tissue. They rely entirely on their host plants for both water and nutrients, and only then emerge as flowers from the roots or lower stems of the host plants.
Westringia is a genus of Australian shrubs. As with other members of the mint family their upper petal is divided into two lobes. There are four stamens - the upper two are fertile while the lower two are reduced to staminodes. The leaves are in whorls of 3 or 4.
Gracillariidae is an important family of insects in the order Lepidoptera and the principal family of leaf miners that includes several economic, horticultural or recently invasive pest species such as the horse-chestnut leaf miner, Cameraria ohridella.
Opostegidae or "white eyecap moths" is a family of insects in the order Lepidoptera that is characterised by particularly large eyecaps over the compound eyes. Opostegidae are most diverse in the New World tropics.
Kevin R. Thiele is currently an adjunct associate professor at the University of Western Australia and the director of Taxonomy Australia. He was the curator of the Western Australian Herbarium from 2006 to 2015. His research interests include the systematics of the plant families Proteaceae, Rhamnaceae and Violaceae, and the conservation ecology of grassy woodland ecosystems. He also works in biodiversity informatics, developing and teaching the development of interactive multi-access keys, and has been involved in the design of software for the Global Biodiversity Information Facility.
Aerva is a genus of plants in the family Amaranthaceae. Its species are native to the palaeotropics, throughout continental Africa, Madagascar and smaller islands, through parts of the Middle East, India, and southeast Asia. Aerva javanica (Burm.f.) Schult. is an alien in northern Australia.
Helicia is a genus of 110 species of trees and shrubs, constituting part of the plant family Proteaceae. They grow naturally in rainforests throughout tropical South and Southeast Asia, including India, Sri Lanka, Indochina, Peninsular Malaysia to New Guinea and as far south as New South Wales.
Ptilotus R.Br. is a genus of approximately 120 species of annual and perennial herbs and shrubs in the family Amaranthaceae. All species are native to mainland Australia, although one species, Ptilotus spathulatus (R.Br.) Poir., also occurs in Tasmania and another, Ptilotus conicus R.Br., in Malesia on the islands of Flores and Timor. Most of the diversity is in Western Australia, particularly in the Pilbara. Common names for species in this genus include mulla mulla, foxtails, pussy tails and lamb's tails. The genus was first formally described by botanist Robert Brown in Prodromus Florae Novae Hollandiae in 1810. In family-level phylogenetic studies, Ptilotus has been placed within a clade informally known as the 'aervoids'. It has been resolved as monophyletic and is closely related to Aerva Forssk. An interactive key to the species of Ptilotus is available at KeyBase.
Ptilotus macrocephalus is a native Australian perennial herb growing up to 50 centimetres (20 in) high. The species was originally described as Trichinium macrocephalum by Robert Brown in 1810 based on specimens from Victoria, Australia. In 1816, it was first transferred to the genus Ptilotus by Jean Louis Marie Poiret. While once considered distributed throughout most of the Australian mainland, current research limits the distribution of P. macrocephalus to south-eastern Australia, mostly in south-eastern South Australia, Victoria and New South Wales. A study by Hammer et al. (2019) determined that specimens previously identified as P. macrocephalus are morphologically and ecologically distinct species, the now named Ptilotus xerophilusT.Hammer & R.W.Davis and Ptilotus psilorhachisT.Hammer & R.W.Davis.
Mangifera indica, commonly known as mango, is a species of flowering plant in the sumac and poison ivy family Anacardiaceae. It is native to the Indian subcontinent where it is indigenous. Hundreds of cultivated varieties have been introduced to other warm regions of the world. It is a large fruit-tree, capable of growing to a height and crown width of about 30 metres (100 ft) and trunk circumference of more than 3.7 metres (12 ft).
The Citrus Industry is a book consisting of five volumes of scientific and experimental information on all the citrus species and varieties, originals as well as hybrids.
Conophytum bilobum is a plant in the family Aizoaceae, native to southern South Africa. It blooms in autumn. It is scentless and grows to a height of 7 cm (2.8 in). The specific epithet bilobum comes from the two-lobed bodies these plants possess.
