Tumbes Region
Tumbes () is a coastal department and region in northwestern Peru bordering Ecuador. Due to the region's location near the Equator it has a warm climate, with beaches that are considered among the finest in Peru. Despite its small area, the region contains a wide variety of ecosystems. It is the smallest department in Peru and its third least populous department after Moquegua and Madre de Dios, but it is also its third most densely populated department, after La Libertad and Lambayeque. The name "Tumbes" originates from either ''Tumpis'', a group of native peoples from the area, the word ''tumbos'', a species of Passiflora that used to abound in the area, or the name of the Tumba cacique, whose son founded and populated the area. Geography The Tumbes Region is bordered by the Ecuadorian provinces of El Oro and Loja on the east; Peru's Piura Region on the south; and by the Pacific Ocean on the north and west. Morphologically, four zones can be defined in the region: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bursera Graveolens
''Bursera graveolens'', known in Spanish as ("Holy Stick”), is a wild tree native from the Yucatán Peninsula to Peru and Venezuela. ''Bursera'' ''graveolens'' is found in the seasonally dry tropical forests of Peru, Venezuela, Colombia, Ecuador, Panama, Costa Rica, Nicaragua, Honduras, Guatemala, and El Salvador,, and on the Galápagos Islands. The tree belongs to the same family (Burseraceae) as frankincense and myrrh. It is widely used in ritual purification and as folk medicine for stomach ache, as a sudorific, and as liniment for rheumatism. Aged heartwood is rich in terpenes such as limonene and α-terpineol. Conservation In 2006, the government of Peru listed ''Bursera graveolens'' as "In Critical Danger" (En Peligro Critico (CR)) under Decree 043-2006-AG, banning the cutting of live trees and allowing only for the collection of naturally fallen or dead trees. However, in 2014, it was removed from the SERFOR (National Forest and Wildlife Service) list of protected spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paspalum
''Paspalum'' is a genus of plants in the grass family. The group is widespread across much of Asia, Africa, Australia, and the Americas. Commonly known as paspalum, bahiagrasses, crowngrasses or dallis grasses, many of the species are tall perennial New World grasses. They are warm-season C4 grasses and are most diverse in subtropical and tropical regions. ''Paspalum scrobiculatum'' (''koda'', ''varuka'', ''varuku'', etc.) is a millet locally grown as food grain. Some species, such as bahiagrass (''P. notatum'') and '' P. nicorae'', are grown for pasturage, especially with the perennial forage peanut (''Arachis glabrata'') as a companion crop. Bahiagrass has also some significance as a honey plant. Water finger-grass (''P. vaginatum'') resembles bermudagrass (''Cynodon dactylon''), but has a higher salinity tolerance and can consume greywater. It is not infrequently used for arena and golf course turf in warmer coastal regions, such as Baja California, Florida, Peru, Texas ...

Distichlis Spicata
''Distichlis spicata'' is a species of grass known by several common names, including seashore saltgrass, inland saltgrass, and desert saltgrass. This grass is native to the Americas, where it is widespread. It can be found on other continents as well, where it is naturalized. It is extremely salt tolerant.Mojave Desert Wildflowers, Pam MacKay, 2nd ed. 2013, p 284 Distribution and habitat ''Distichlis spicata'' thrives along coastlines and on salt flats and disturbed soils, as well as forest, woodland, montane, and desert scrub habitats. It can form dense monotypic stands, and it often grows in clonal colonies. Non-clonal populations tend to be skewed toward a majority of one sex or the other. The grass forms sod with its hearty root system. Its rhizomes have sharp points which allow it to penetrate hard soils and aerenchymous tissues, which allow it to grow underwater and in mud. This plant grows easily in salty and alkaline soils, excreting salts from its tissues via salt gla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scirpus
''Scirpus'' is a genus of grass-like species in the sedge family Cyperaceae many with the common names club-rush, wood club-rush or bulrush (see also bulrush for other plant genera so-named). They mostly inhabit wetlands and damp locations. Taxonomy The taxonomy of the genus is complex, and under review by botanists. Recent studies by taxonomists of the Cyperaceae have resulted in the creation of several new genera, including the genera '' Schoenoplectus'' and ''Bolboschoenus''; others (including ''Blysmus'', '' Isolepis'', '' Nomochloa'', and '' Scirpoides'') have also been used. At one point this genus held almost 300 species, but many of the species once assigned to it have now been reassigned, and it now holds an estimated 120 species. Description ''Scirpus'' are rhizomatous perennial herbs, with 3-angled stems and flat grass-like leaves. The flowers are in clusters of small spikelets, often brown or greenish brown. Some species (e.g. ''S. lacustris'') can reach a height of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyperus
''Cyperus'' is a large genus of about 700 species of sedges, distributed throughout all continents in both tropical and temperate regions. Description They are annual or perennial plants, mostly aquatic and growing in still or slow-moving water up to deep. The species vary greatly in size, with small species only tall, while others can reach in height. Common names include ''papyrus sedges'', ''flatsedges'', ''nutsedges'', ''umbrella-sedges'' and ''galingales''. The stems are circular in cross-section in some, triangular in others, usually leafless for most of their length, with the slender grass-like leaves at the base of the plant, and in a whorl at the apex of the flowering stems. The flowers are greenish and wind-pollinated; they are produced in clusters among the apical leaves. The seed is a small nutlet. Ecology ''Cyperus'' species are eaten by the larvae of some Lepidoptera species, including '' Chedra microstigma''. They also provide an alternative food source f ...

Tephrosia
''Tephrosia'' is a genus of flowering plants in the pea family, Fabaceae. It is widespread in both the Eastern and Western Hemisphere, where it is found in tropical and warm-temperate regions. The generic name is derived from the Greek word τεφρος (''tephros''), meaning "ash-colored," referring to the greyish tint given to the leaves by their dense trichomes. Hoarypea is a common name for plants in this genus, along with Goat's Rue and Devil's Shoestring. Uses Many species in the genus are poisonous, particularly to fish, for their high concentration of rotenone. The black seeds of ''Tephrosia'' species have historically been used by indigenous cultures as fish toxins.NTFlora Northern Territory Flora online:''Flora of the Darwin Region: Fabaceae.''Retrieved 10 June 2018 In the last century, several ''Tephrosia'' species have been studied in connection with the use of rotenone as an insecticide and pesticide.

Crotalaria
''Crotalaria'' is a genus of flowering plants in the family Fabaceae (subfamily Faboideae) commonly known as rattlepods. The genus includes over 700 species of herbaceous plants and shrubs. Africa is the continent with the majority of ''Crotalaria'' species (approximately 400 species), which are mainly found in damp grassland, especially in floodplains, depressions and along edges of swamps and rivers, but also in deciduous bush land, roadsides and fields. Some species of ''Crotalaria'' are grown as ornamentals. The common name rattlepod or rattlebox is derived from the fact that the seeds become loose in the pod as they mature, and rattle when the pod is shaken. The name derives from the Ancient Greek , meaning "castanet", and is the same root as the name for the rattlesnakes (''Crotalus''). ''Crotalaria'' species are used as food plants by the larvae of some Lepidoptera species including ''Endoclita sericeus'', '' Etiella zinckenella'' and '' Utetheisa ornatrix''. The toxic alka ...
