It usually reaches a height of , sometimes growing up to tall, with a stem diameter of . Taxonomy American botanist George Proctor considered ''A. media'' to be a valid species on the basis of its shorter, more slender trunk, but other authors considered it a synonym of '' A. aculeata''.

Orator F
An orator, or oratist, is a public speaker, especially one who is eloquent or skilled. Etymology Recorded in English c. 1374, with a meaning of "one who pleads or argues for a cause", from Anglo-French ''oratour'', Old French ''orateur'' (14th century), Latin ''orator'' ("speaker"), from ''orare'' ("speak before a court or assembly; plead"), derived from a Proto-Indo-European base *''or-'' ("to pronounce a ritual formula"). The modern meaning of the word, "public speaker", is attested from c. 1430. History In ancient Rome, the art of speaking in public (''Ars Oratoria'') was a professional competence especially cultivated by politicians and lawyers. As the Greeks were still seen as the masters in this field, as in philosophy and most sciences, the leading Roman families often either sent their sons to study these things under a famous master in Greece (as was the case with the young Julius Caesar), or engaged a Greek teacher (under pay or as a slave).

Arecaceae
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 imp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Virgin Islands
The Virgin Islands ( es, Islas Vírgenes) are an archipelago in the Caribbean Sea. They are geology, geologically and biogeography, biogeographically the easternmost part of the Greater Antilles, the northern islands belonging to the Puerto Rico Trench and St. Croix being a displaced part of the same geologic structure. Politically, the British Virgin Islands have been governed as the western archipelago, island group of the Leeward Islands, which are the northern part of the Lesser Antilles, and form the border between the Caribbean Sea and the Atlantic Ocean. The archipelago is separated from the true Lesser Antilles by the Anegada Passage and from the List of islands of Puerto Rico, main island of Puerto Rico by the Virgin Passage. The islands fall into three different jurisdiction (area), political jurisdictions: * British Virgin Islands, Virgin Islands, informally referred to as British Virgin Islands, a British Overseas Territories, British overseas territory, * Virgin I ...

Pinnate
Pinnation (also called pennation) is the arrangement of feather-like or multi-divided features arising from both sides of a common axis. Pinnation occurs in biological morphology, in crystals, such as some forms of ice or metal crystals, and in patterns of erosion or stream beds. The term derives from the Latin word ''pinna'' meaning "feather", "wing", or " fin". A similar concept is "pectination," which is a comb-like arrangement of parts (arising from one side of an axis only). Pinnation is commonly referred to in contrast to "palmation," in which the parts or structures radiate out from a common point. The terms "pinnation" and "pennation" are cognate, and although they are sometimes used distinctly, there is no consistent difference in the meaning or usage of the two words.Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co.

George Proctor (botanist)
George Richardson Proctor (1920–2015) was an American botanist and expert on Jamaican flora. He wrote widely on the topic, publishing ''Flora of the Cayman Islands'', and collected over 55,000 specimens from 50 different islands in the Caribbean. He was considered one of the "four horsemen" of taxonomy in the West Indies and Caribbean. Thirty-one species were named in his honor, including ''Coccothrinax proctorii''. Late in his life Proctor was arrested for a conspiracy to murder his wife at the age of 86, and in 2010 at the age of 90, was sentenced to four years in prison. Proctor was released after two, spending the rest of his life in the United States. Biography George Richardson Proctor was born in 1920 in Boston, Massachusetts. He received a PhD from the University of Pennsylvania after World War II. While in college, from 1946 to 1947, Proctor worked at the Academy of Natural Sciences in Philadelphia. He was first published at the age of 19. In 1948, he traveled to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acrocomia Aculeata
''Acrocomia aculeata'' is a species of palm native to the Neotropics, from southern Mexico and the Caribbean south to Paraguay and northern Argentina. Common names include grugru palm, gloo gloo, macaúba palm, coyol palm, and macaw palm; synonyms include ''A. lasiospatha, A. sclerocarpa'', and ''A. vinifera''. The fruit turns yellow when ripe and has a hard outer shell. The pulp is slightly sweet and is extremely slimy and sticky. Description It grows up to 15–20 m tall, with a trunk up to 50 cm in diameter, characterized by numerous slender, black, viciously sharp 10 cm long spines jutting out from the trunk. The leaves are pinnate, 3–4 m long, with numerous slender, 50–100 cm long leaflets. Petioles of the leaves are also covered with spines. The flowers are small, produced on a large branched inflorescence 1.5 m long. The fruit is a yellowish-green drupe 2.5–5 cm in diameter.

Acrocomia
''Acrocomia'' is a genus of palms which is native to the Neotropics, ranging from Mexico in the north, through Central America and the Caribbean, and through South America south to Argentina. Description ''Acrocomia'' is a genus of spiny, pinnate-leaved palms which range from large trees to small palms with short, subterranean stems. The species bears branched inflorescences which are located among the leaves. The unisexual flowers; female flowers are born near the base of the inflorescence, while male flowers are borne towards the tips. Fruit are large, single-seeded, and vary in colour from yellow, to orange, to brown. Ricardo Vargas‑Carpintero et al. have concluded that "main research gaps are associated with genotype–environment interaction, planting material, crop management, and sustainable cropping systems. Overall, we conclude that acrocomia is at an early phase of development as an alternative and multipurpose crop and its up-scaling requires the integration of ...

Trees Of Puerto Rico
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 co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
