Stegnospermataceae
''Stegnosperma'' is a genus of flowering plants, consisting of three species of woody plants, native to the Caribbean, Central America, and the Sonoran Desert. These are shrubs or lianas, with anomalous secondary thickening in mature stems, by successive cambia. Characteristics Leaves are alternate, entire, 2–5 cm in length, tapering at both ends. Flowers are small (5–8 mm), five-merous, with white petal-like sepals, and a superior ovary. They are arranged in short racemes, usually no more than 10 cm long, shorter in ''S. watsonii''. The fruit is a capsule 5–8 mm in diameter: it contains small (2–3 mm) black seeds with a conspicuous reddish aril. The genus has commonly been treated as belonging to the family Phytolaccaceae, but the APG system and APG II system, of 2003, regard it as the sole genus of its own family, the Stegnospermataceae and assign it to the order Caryophyllales in the clade core eudicots Turner et al. suggest that ''S. hali ...

APG System
The APG system (Angiosperm Phylogeny Group system) of plant classification is the first version of a modern, mostly molecular-based, system of plant taxonomy. Published in 1998 by the Angiosperm Phylogeny Group, it was replaced by the improved APG II in 2003, APG III system in 2009 and APG IV system in 2016. History The original APG system is unusual in being based, not on total evidence, but on the cladistic analysis of the DNA sequences of three genes, two chloroplast genes and one gene coding for ribosomes. Although based on molecular evidence only, its constituent groups prove to be supported by other evidence as well, for example pollen morphology supports the split between the eudicots and the rest of the former dicotyledons. The system is rather controversial in its decisions at the family level, splitting a number of long-established families and submerging some other families. It also is unusual in not using botanical names above the level of order, that is, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phytolaccaceae
Phytolaccaceae is a family (biology), family of flowering plants. Though almost universally recognized by Taxonomy (biology), taxonomists, its circumscription has varied. It is also known as the Pokeweed family. The APG II system, of 2003 (unchanged from the APG system, of 1998), also recognizes this family and assigns it to the order Caryophyllales in the clade core eudicots. The family comprises five Genus, genera, totalling 33 known species. It is divided into the subfamilies Agdestioideae and Phytolaccoideae, with the former Rivinioideae in the Takhtajan system, now placed in its own family Petiveriaceae Genera and species The Phytolaccaceae includes the following genera: *''Agdestis'' Moc. & Sessé ex DC. — 1 species *''Anisomeria (plant), Anisomeria'' D.Don — 3 species *''Ercilla (plant), Ercilla'' A.Juss. — 2 species *''Nowickea'' J.Martínez & J.A.McDonald — 2 species *''Phytolacca'' L. — ca 25 species Former genera The following genera were previously in ...

Raceme
A raceme () or racemoid is an unbranched, indeterminate growth, indeterminate type of inflorescence bearing flowers having short floral stalks along the shoots that bear the flowers. The oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. Examples of racemes occur on mustard (genus ''Brassica''), radish (genus ''Raphanus''), and orchid (genus ''Phalaenopsis'') plants. Definition A ''raceme'' or ''racemoid'' is an unbranched, indeterminate growth, indeterminate type of inflorescence bearing pedicellate flowers (flowers having short floral stalks called ''Pedicel (botany), pedicels'') along its axis. In botany, an ''axis'' means a shoot, in this case one bearing the flowers. In indeterminate inflorescence-like racemes, the oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. A plant that flowers on a showy raceme may hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gulf Of California
The Gulf of California (), also known as the Sea of Cortés (''Mar de Cortés'') or Sea of Cortez, or less commonly as the Vermilion Sea (''Mar Vermejo''), is a marginal sea of the Pacific Ocean that separates the Baja California peninsula from the Mexico, Mexican mainland. It is bordered by the states of Baja California, Baja California Sur, Sonora, and Sinaloa with a coastline of approximately . Rivers that flow into the Gulf of California include the Colorado River, Colorado, Fuerte River, Fuerte, Mayo River (Mexico), Mayo, Sinaloa River, Sinaloa, Sonora River, Sonora, and the Yaqui River, Yaqui. The surface of the gulf is about . Maximum depths exceed because of the complex geology, linked to plate tectonics. The gulf is thought to be one of the most diverse seas on Earth and is home to more than 5,000 species of micro-invertebrates. Parts of the Gulf of California are a UNESCO World Heritage Site.

Sonora
Sonora (), officially Estado Libre y Soberano de Sonora (), is one of the 31 states which, along with Mexico City, comprise the Administrative divisions of Mexico, Federal Entities of Mexico. The state is divided into Municipalities of Sonora, 72 municipalities; the capital (and largest) city of which is Hermosillo, located in the center of the state. Other large cities include Ciudad Obregón, Nogales, Sonora, Nogales (on the Mexico–United States border, Mexico-United States border), San Luis Río Colorado, and Navojoa. Sonora is bordered by the states of Chihuahua (state), Chihuahua to the east, Baja California to the west (of the north portion) and Sinaloa to the southeast. To the north, it shares a border with the United States, and on the southwest has a significant share of the coastline of the Gulf of California. Sonora's natural geography is divided into three parts: the Sierra Madre Occidental in the east of the state; plains and rolling hills in the center; and the co ...

Core Eudicots
The eudicots or eudicotyledons are flowering plants that have two seed leaves (cotyledons) upon germination. The term derives from ''dicotyledon'' (etymologically, ''eu'' = true; ''di'' = two; ''cotyledon'' = seed leaf). Historically, authors have used the terms tricolpates or non-magnoliid dicots. The current botanical terms were introduced in 1991, by evolutionary botanist James A. Doyle and paleobotanist Carol L. Hotton, to emphasize the later evolutionary divergence of tricolpate dicots from earlier, less specialized, dicots. Scores of familiar plants are eudicots, including many commonly cultivated and edible plants, numerous trees, tropicals and ornamentals. Among the most well-known eudicot genera are those of the sunflower (''Helianthus''), dandelion (''Taraxacum''), forget-me-not ('' Myosotis''), cabbage ('' Brassica''), apple (''Malus''), buttercup ('' Ranunculus''), maple ('' Acer'') and macadamia (''Macadamia'').
