Acrocomia media is a species of palm which is native to Puerto Rico and the Virgin Islands.
Acrocomia media is a pinnately leaved palm with a solitary, stout stem. It usually reaches a height of 8 to 10 metres (26 to 33 ft), sometimes growing up to 15 metres (49 ft) tall, with a stem diameter of 20 to 30 centimetres (7.9 to 11.8 in). [1]
American botanist George Proctor considered A. media to be a valid species on the basis of its shorter, more slender trunk, [1] but other authors considered it a synonym of A. aculeata . [2] [3]
Acrocomia media is commonly known as coroso or palma de coroso in Puerto Rico. [1]
The geography of Puerto Rico consists of an archipelago located between the Caribbean Sea and the North Atlantic Ocean, east of the Dominican Republic, west of the Virgin Islands and north of Venezuela. The main island of Puerto Rico is the smallest and most eastern of the Greater Antilles. With an area of 3,515 square miles (9,104 km2), it is the third largest island in the United States and the 82nd largest island in the world. Various smaller islands and cays, including Vieques, Culebra, Mona, Desecheo, and Caja de Muertos comprise the remainder of the archipelago with only Culebra and Vieques being inhabited year-round. Mona is uninhabited through large parts of the year except for employees of the Puerto Rico Department of Natural Resources.
Territories of the United States are sub-national administrative divisions overseen by the United States government. The various U.S. territories differ from the U.S. states and Native American tribes in that they are not sovereign entities. In contrast, each state has a sovereignty separate to that of the federal government and each federally-recognized Native American tribe possesses limited tribal sovereignty as a "dependent sovereign nation". Territories are classified by incorporation and whether they have an "organized" government through an organic act passed by the Congress. U.S. territories are under U.S. sovereignty and, consequently, may be treated as part of the United States proper in some ways and not others. Unincorporated territories in particular are not considered to be integral parts of the United States, and the Constitution of the United States applies only partially in those territories.
The Puerto Rico Trench is located on the boundary between the Caribbean Sea and the Atlantic Ocean. The oceanic trench, the deepest in the Atlantic, is associated with a complex transition between the Lesser Antilles subduction zone to the south and the major transform fault zone or plate boundary, which extends west between Cuba and Hispaniola through the Cayman Trough to the coast of Central America.
Aiphanes is a genus of spiny palms which is native to tropical regions of South and Central America and the Caribbean. There are about 26 species in the genus, ranging in size from understorey shrubs with subterranean stems to subcanopy trees as tall as 20 metres (66 ft). Most have pinnately compound leaves ; one species has entire leaves. Stems, leaves and sometimes even the fruit are covered with spines. Plants flower repeatedly over the course of their lifespan and have separate male and female flowers, although these are borne together on the same inflorescence. Although records of pollinators are limited, most species appear to be pollinated by insects. The fruit are eaten by several birds and mammals, including at least two species of amazon parrots.
Dypsis lutescens, also known as golden cane palm, areca palm, yellow palm, or butterfly palm, is a species of flowering plant in the family Arecaceae, native to Madagascar and naturalized in the Andaman Islands, Réunion, El Salvador, Cuba, Puerto Rico, the Canary Islands, southern Florida, Haiti, the Dominican Republic, Jamaica, the Leeward Islands and the Leeward Antilles.
Aiphanes minima is a spiny palm tree which is native to the insular Caribbean from Hispaniola to Grenada, and widely cultivated elsewhere. Usually 5–8 metres (16–26 ft) tall, it sometimes grows as an understorey tree and only 2 m (6.6 ft) in height.
Coccothrinax barbadensis is a palm found in the Lesser Antilles. Like other members of the genus Coccothrinax, C. barbadensis is a fan palm. The leaves are widely used to thatch roofs.
Coccothrinax alta is a palm which is native to Puerto Rico and the Virgin Islands. Like other members of the genus, C. alta is a fan palm. Trees are 2–6 m tall, with some individuals getting up to 11 m. Flowers are light yellow, and fruit are purple-black when ripe. It is found on lower elevations, but to 350 m above sea level.
Calyptronoma is a genus in the palm family, native to the Greater Antilles. They have pinnately compound leaves with short petioles. The name was coined by August Grisebach who first described the genus in his 1846 Flora of the British West Indian Islands.
Calyptronoma rivalis is a pinnately compound leaved palm species that is found on Hispaniola and Puerto Rico. Its common names include palma de manaca and Puerto Rican manac.
Gaussia is a genus in the palm family, native to Mexico, Central America and the Greater Antilles. They are solitary, unarmed, and have pinnately compound leaves. The trees have enlarged bases and prop-roots.
Acrocomia crispa, the Cuban belly palm or Corojo palm, 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.
Gaussia attenuata is a palm which is native to the Dominican Republic and Puerto Rico. The species grows on steep-sided limestone hills in Puerto Rico.
Roystonea borinquena, commonly called the Puerto Rico royal palm, is a species of palm which is native to Hispaniola, Puerto Rico and the Virgin Islands.
Leucothrinax morrisii, the Key thatch palm, is a small palm which is native to the Greater Antilles, northern Lesser Antilles, The Bahamas and the Florida Keys. Until 2008 it was known as Thrinax morrisii. It was split from the genus Thrinax after phylogenetic studies showed that its inclusion in Thrinax would render that genus paraphyletic. The generic name combines leuco with thrinax.
Sabal causiarum, commonly known as the Puerto Rico palmetto or Puerto Rican hat palm, is a species of palm which is native to Hispaniola, Puerto Rico, the United States Virgin Islands, and the British Virgin Islands. As its common and scientific names suggest, its leaves are used in the manufacture of "straw" hats.
Sabal mauritiiformis is a species of palm which is ranges from Mexico, Central America, Colombia, Venezuela and Trinidad.
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.
Isla Magueyes is a 7.2 hectares island 50 metres (160 ft) from the southwest coast of the island of Puerto Rico. It is encircled with mangrove and has an interior of dry scrub habitat, where it gets its name. It is named for the presence of many century plants or maguey. The surrounding shelf of the island is mostly coral reef. There are buildings on the western end of the island associated with the Department of Marine Sciences, University of Puerto Rico at Mayagüez. UPR- Mayagüez is the most important center in the Atlantic region for the study of tropical marine science due to its location, facilities, and first-rate researchers. The research facilities includes the Puerto Rico Water Resources and Environmental Research Institute, the Caribbean Coral Reef Institute (CCRI), the Research and Development Center, the Agricultural Research Station and the Caribbean Atmospheric Research Center (ATMOSCarib).
