Bactris Tefensis
''Bactris'' is a genus of spiny Arecaceae, palms which are native to Mexico, South and Central America and the Caribbean. Most species are small trees about tall, but some are large trees while others are shrubs with subterranean stems. They have simple or pinnately compound leaves and yellow, orange, red or purple-black fruit. The genus is most closely related to several other spiny palms—''Acrocomia'', ''Aiphanes'', ''Astrocaryum'' and ''Desmoncus''. The fruit of several species is edible, most notably ''Bactris gasipaes, B. gasipaes'', while others are used medicinal plants, medicinally or for construction. The ancestors of the genus are believed to have entered South America during the late Cretaceous. ''Bactris'' shows high rates of speciation. Description Both stems and leaves of ''Bactris'' species are generally covered with Thorns, spines, and prickles, spines. Stems generally bear spines on the internodes; in ''Bactris glaucescens, B. glaucescens'' and ''Bactris setul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bactris Gasipaes
''Bactris gasipaes'' is a species of palm native to the tropical forests of Central and South America. It is well spread in these regions, where it is often cultivated by smallholders in agroforestry systems or more rarely, in monoculture. Common names include peach palm in English, among others used in South American countries. It is a long-lived perennial plant that is productive for 50 to 75 years on average. Its population has an important genetic diversity, leading to numerous fruits, colors, and qualities. The fruits are edible and nutritious but need to be cooked for 30 minutes to five hours. They also benefit many animals in the wild. Peach-palms are also cultivated for the heart of palm, and the trunk can make valuable timber. Description ''Bactris gasipaes'', like most sea-island palms, grows erect, with a single slender stem or, more often, several stems that are up to eight inches (20 cm) thick, in a cluster; generally armed with stiff, black spines in circular ...

Cocoseae
Cocoseae is a tribe of cocosoid palms of the family Arecaceae. Description The fruit of the Cocoseae is a modified drupe, with a sclerenchymatous epicarp and a highly developed mesocarp, formed mainly by parenchyma . The endocarp is generally sclerenchymatous and protects the seeds from predation and drying. The most obvious synapomorphy In phylogenetics, an apomorphy (or derived trait) is a novel character or character state that has evolved from its ancestral form (or plesiomorphy). A synapomorphy is an apomorphy shared by two or more taxa and is therefore hypothesized to have ... of the species of this tribe is the presence, in the endocarp, of three or more "eyes" or pores of germination. Distribution The Cocoseae are distributed mainly in the Neotropical regions, with two genera endemic to Africa (''Jubaeopsis'' and ''Elaeis'') and Madagascar ( ''Beccariophoenix'' and ''Voanioala'' ), respectively. Systematics The Cocoseae in the sense of Dransfield et al. (2008) are ide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tribe (biology)
In biology, a tribe is a taxonomic rank above genus, but below family and subfamily. It is sometimes subdivided into subtribes. By convention, all taxonomic ranks from genus upwards are capitalized, including both tribe and subtribe. In zoology, the standard ending for the name of a zoological tribe is "-ini". Examples include the tribes Caprini (goat-antelopes), Hominini (hominins), Bombini (bumblebees), and Thunnini (tunas). The tribe Hominini is divided into subtribes by some scientists; subtribe Hominina then comprises "humans". The standard ending for the name of a zoological subtribe is "-ina". In botany, the standard ending for the name of a botanical tribe is "-eae". Examples include the tribes Acalypheae and Hyacintheae. The tribe Hyacintheae is divided into subtribes, including the subtribe Massoniinae. The standard ending for the name of a botanical subtribe is "-inae". In bacteriology, the form of tribe names is as in botany, e.g., Pseudomonadeae, based on the ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arecoideae
The Arecaceae is a family of perennial flowering plants in the monocot order Arecales. Their growth form can be climbers, shrubs, tree-like and stemless plants, all commonly known as palms. Those having a tree-like form are called palm trees. Currently, 181 genera with around 2,600 species are known, most of which are restricted to tropical and subtropical climates. Most palms are distinguished by their large, compound, evergreen leaves, known as fronds, arranged at the top of an unbranched stem. However, palms exhibit an enormous diversity in physical characteristics and inhabit nearly every type of habitat within their range, from rainforests to deserts. Palms are among the best known and most extensively cultivated plant families. They have been important to humans throughout much of history. Many common products and foods are derived from palms. In contemporary times, palms are also widely used in landscaping. In many historical cultures, because of their importance as ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Acrocomia Crispa
''Acrocomia crispa'', the Cuban belly palm or corojo, a palm species which is endemic to Cuba. Formerly placed in its own genus, ''Gastrococos'', recent work found that that genus was nested within ''Acrocomia''. It is a tall, spiny palm with a trunk that is slender at the base, but swollen in the middle, giving it the name "Cuban belly palm" in English. Description ''Acrocomia crispa'' is a single-stemmed palm tree with pinnately-compound leaves. Stems are tall, with a distinct, "spindle-shaped" bulge halfway up the stem. Trunks are densely spiny, but becomes smooth and grey as the trunk ages. Trees have 10-20 leaves which are up to with leaflets which are approximately opposite. Taxonomy The species was first described by as ''Cocos crispa'' by Carl Sigismund Kunth in 1816 based on an incomplete specimen collected by Alexander von Humboldt and Aimé Bonpland. In 1866 Sebastián Alfredo de Morales described ''Gastrococcus armentalis'' based on a distinct type species. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aiphanes Aculeata
''Aiphanes horrida'' is a palm native to northern South America and Trinidad and Tobago. ''Aiphanes horrida'' is a solitary, spiny tree. In the wild it grows 3–10 metres tall (9–30 feet) tall with a stem diameter of 6–10 centimetres (2–4 inches); cultivated trees may be as much as 15 m (49') tall with a 15 cm (6") diameter.

Phylogeny
A phylogenetic tree (also phylogeny or evolutionary tree Felsenstein J. (2004). ''Inferring Phylogenies'' Sinauer Associates: Sunderland, MA.) is a branching diagram or a tree showing the evolutionary relationships among various biological species or other entities based upon similarities and differences in their physical or genetic characteristics. All life on Earth is part of a single phylogenetic tree, indicating common ancestry. In a ''rooted'' phylogenetic tree, each node with descendants represents the inferred most recent common ancestor of those descendants, and the edge lengths in some trees may be interpreted as time estimates. Each node is called a taxonomic unit. Internal nodes are generally called hypothetical taxonomic units, as they cannot be directly observed. Trees are useful in fields of biology such as bioinformatics, systematics, and phylogenetics. ''Unrooted'' trees illustrate only the relatedness of the leaf nodes and do not require the ancestral root to be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
