Bactris Campestris
''Bactris campestris'' is a small (1–5 m tall) Thorns, spines, and prickles, spiny Arecaceae, palm which grows in multi-stemmed clumps in savannas and low forests in northern South America from Colombia to the Guianas, Trinidad and Tobago, and northern Brazil. Description ''Bactris campestris'' grows in small, multi-stemmed clumps. The stems, which are tall and in diameter, are often sheathed by the remains of old leaf bases. Stems usually bear between two and five leaves which are covered with flattened greyish-brown spines in length. The leaf sheath and petiole (botany), petiole are densely covered with spines; those on the rachis are less dense and grow mostly on the lower surface. The leaf sheath is long, the petiole and the rachis . Each leaf consists of 17 to 32 leaflets which clustered in groups of two to five. The largest of the leaflets are long and broad. The inflorescence consists of a -long peduncle (botany), peduncle and -long rachis, off of which branches b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eduard Friedrich Poeppig
Eduard Friedrich Poeppig (16 July 1798 – 4 September 1868) was a German botanist, zoologist and explorer. Biography Poeppig was born in Plauen, Saxony. He studied medicine and natural history at the University of Leipzig, graduating with a medical degree. On graduation, the rector of the university gave him a botanical mission to North and South America. He was helped out financially by a small group of friends and scientists in Leipzig, that included botanist Christian Friedrich Schwägrichen, who in exchange, received sets of specimens.JSTOR Global Plants Poeppig, Eduard Friedrich (1798-1868) He subsequently worked as a naturalist in (1823–24) and |
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 opi ...

Trees Of South America
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heart Of Palm
Heart of palm is a vegetable harvested from the inner core and growing bud of certain palm trees, most notably the coconut (''Cocos nucifera''), juçara (''Euterpe edulis''), açaí palm (''Euterpe oleracea''), palmetto (''Sabal'' spp.), and peach palm. Harvesting of many uncultivated or wild single-stemmed palms results in palm tree death (e.g. ''Geonoma edulis''). However, other palm species are clonal or multi-stemmed plants (e.g. ''Prestoea acuminata'', ''Euterpe oleracea''), and moderate harvesting will not kill the entire clonal palm. Heart of palm may be eaten on its own, and often it is eaten in a salad. There are palm varieties that have become domesticated farm species as an alternative to sourcing from wild palms. The main variety that has been domesticated is '' Bactris gasipaes'', known in English as peach palm. This variety is the most widely used for canning. Peach palms are self- suckering and produce multiple stems, with up to 40 on one plant. This lets produce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bactris Pliniana
''Bactris'' is a genus of spiny 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 '' B. gasipaes'', while others are used 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 spines. Stems generally bear spines on the internodes; in '' B. glaucescens'' and '' B. setulosa'' spines are also present on the nodes. A few species lack spines on their stems. All species ...

Plastid
The plastid (Greek: πλαστός; plastós: formed, molded – plural plastids) is a membrane-bound organelle found in the cells of plants, algae, and some other eukaryotic organisms. They are considered to be intracellular endosymbiotic cyanobacteria. Examples include chloroplasts (used for photosynthesis), chromoplasts (used for pigment synthesis and storage), and leucoplasts (non-pigmented plastids that can sometimes differentiate). The event which led to permanent endosymbiosis in the Archaeplastida clade (of land plants, red algae, and green algae) probably occurred with a cyanobiont (a symbiotic cyanobacteria) related to the genus '' Gloeomargarita'', around 1.5 billion years ago. A later primary endosymbiosis event occurred in photosynthetic ''Paulinella'' amoeboids about 90–140 million years ago. This plastid belongs to the "PS-clade" (of the cyanobacteria genera ''Prochlorococcus'' and ''Synechococcus''). Secondary and tertiary endosymbiosis has also occurred, in a wid ...

Monophyly
In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics (synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have take ...

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 hav ... 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 id ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tribe (biology)
In biology, a tribe is a taxonomic rank above genus, but below family (biology), 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 Goat-antelope#Tribe Caprini, 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 Scilloideae#Hyacintheae, 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 ...

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 importanc ...
