Bactris Guineensis
''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 Arecaceae, palm native to the tropical forests of Central America, 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 language, 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 thick, in a cluster; generally armed with stiff, bla ...

Cocoseae
Cocoseae is a tribe (biology), 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 of the species of this tribe is the presence, in the endocarp, of three or more "eyes" or pores of germination. According to Thomas C. Whitmore all Cocosoid palms have inflorescences in which the flowers are in triads (sets of three flowers). 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 identified as natural relatives (monophylum) in most studies. Their systematic position within the Arecoideae ...

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 taxa ranked above species 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 colloquially 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, except for the Hyphaene genus, who has branched palms. 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, especially in regions like the Middle East and North Africa. A wide range of common products and foods are deri ...

Family (biology)
Family (, : ) 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". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Acrocomia Crispa
''Acrocomia crispa'', also known as 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. The young palm tree stems are edible by humans and animals; the ripe fruit ripe is used to produce cooking oil and for animal feed. 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 Alexande ...

Phylogeny
A phylogenetic tree or phylogeny is a graphical representation which shows the evolutionary history between a set of species or Taxon, taxa during a specific time.Felsenstein J. (2004). ''Inferring Phylogenies'' Sinauer Associates: Sunderland, MA. In other words, it is a branching diagram or a tree (graph theory), tree showing the evolutionary relationships among various biological species or other entities based upon similarities and differences in their physical or genetic characteristics. In evolutionary biology, all life on Earth is theoretically part of a single phylogenetic tree, indicating common ancestry. Phylogenetics is the study of phylogenetic trees. The main challenge is to find a phylogenetic tree representing optimal evolutionary ancestry between a set of species or taxa. computational phylogenetics, Computational phylogenetics (also phylogeny inference) focuses on the algorithms involved in finding optimal phylogenetic tree in the phylogenetic landscape.
