Chamaedorea costaricana is a species of palm in the genus Chamaedorea , found in Central America. A common local name in Costa Rica is pacaya, [1] though this is also used as a name for Chamaedorea tepejilote .
They grow in colonies, with short horizontal stems under or at ground level, forming dense or open clumps, up to 6 m high and 2-6 cm in diameter, with internodes 5-30 cm long. Leaves 4-6, are erect-patent, pinnate 1-2 m long; with pinnae 20-26 on each side, slightly sigmoid or falcate, 25-40 cm long and 2.5-5 cm wide, long acuminate, 2 prominent nerves on each side of the main nerve, rachis 100-120 cm long; tubular sheath, 20-60 cm long, with an elongated triangular extension opposite the petiole insertion, forming auriculated lobes on each side of the petiole. The petiole is up to 35 cm long, abaxially with a pale band that extends to the sheath. Infrafoliar inflorescences, solitary, with peduncle 20-45 cm long, erect in flower, pendulum in fruit, bracts 5-8, rachis 10-20 cm long; inflorescences staminated with 15-30 splints, 20-30 cm long, flexuous and pendulous, green to yellow in flower, flowers 2.5-3.5 mm long and 2.5-3 mm wide, yellow-greenish, sepals free almost to the base, petals valved, free almost to the base; pistillate inflorescences with 10-20 slivers, 20-35 cm long, frequently only bifid, orange and bulging in fruit, flowers 3-3.5 mm long and 2-2.5 mm wide, in lax spirals, pale yellow, slightly sunken, sepals connate briefly at the base, petals imbricated almost to the apex, free. Fruits are globose to subglobose, 7-10 mm in diameter, green when unripe and turning black or black-purple when ripe.
It is found throughout Mexico and Central America, in Guatemala, Honduras, Costa Rica, Nicaragua, Panama, and El Salvador.
It is a common species in humid or very humid forests, cloud forests, and dwarf forests, at an altitude of 600-1650 meters. [1] It tolerates full sun, but is found to prefer shade in hot, inland climates. [2]
Syngonium is a genus of flowering plants in the family Araceae, native to tropical rain forests in southern Mexico, the West Indies, Central and South America. They are woody vines growing to heights of 10–20 m or more in trees. They have leaves that change shape according to the plant's stage of growth, and adult leaf forms are often much more lobed than the juvenile forms usually seen on small house plants. The scientific name of the genus comes from the Greek words σύν and γονή and refers to the fused ovaries of female flowers.
Echinodorus tunicatus is a species of aquatic plants in the family Alismataceae.
Desmoncus is a genus of mostly climbing, spiny palms native to the Neotropics. The genus extends from Mexico in the north to Brazil and Bolivia in the south, with two species present in the southeastern Caribbean.
Attalea crassispatha is a palm which is endemic to southwest Haiti. The most geographically isolated member of the genus, it is considered a critically endangered species and has been called one of the rarest palms in the Americas.
Butia purpurascens is a smallish, relatively slender, endangered species of Butia palm, up to 3-7m tall. It is locally known as palmeira-jataí, coqueiro-de-vassoura, butiá or coquinho-azedo in Portuguese. The Kalunga people call this palm cabeçudo.
Dypsis ambositrae is a species of flowering plant in the family Arecaceae. It is found only in Madagascar where it is threatened by habitat loss.
Lytocaryum is a monoecious genus of flowering plant in the palm family endemic to Brazil where 4 species are known. Palms once classified as Microcoelum are herein included; the genus is closely related to Syagrus, from which it is differentiated only by abundant tomentum, strongly versatile anthers, and slight epicarp, mesocarp, and endocarp differences. The name is Greek for "loose" and "nut".
Neonicholsonia is a monotypic genus of flowering plant in the palm family native to Central America. The sole species is Neonicholsonia watsonii. The genus and species names honor George Nicholson, a former curator of the Royal Botanic Gardens, Kew and his successor William Watson.
Allagoptera caudescens is a species of flowering plant in the palm family endemic to Brazil, where it is known as buri palm. The name combines the Greek words for "many" and "anther" with the name of another palm genus Cocos, and the epithet is Latin for "bearlike", referring to the hairy tomentum. It was formerly classified as Polyandrococos caudescens, the only species in the genus Polyandrococos.
Ptychococcus is a monoecious genus of flowering plant in the palm family from New Guinea and the Solomon Islands. They are closely related to Ptychosperma, only differentiated by the seed shape and endocarp type. The name is a combination of the Greek for "fold" and the Latin for "berry".
Synechanthus is a monoecious genus of flowering plant in the palm family found in Mexico, Central and South America. Commonly called bola, palmilla, or jelly bean palm, they are closely related to members of Chamaedorea, only distinguished by their flower and fruit form. The Greek genus name is a combination of "united" and "flower".
Tillandsia ionantha, the air plant, is a species in the genus Tillandsia. This species is native to Central America and Mexico. It is also reportedly naturalized in Broward County, Florida.

Gunnera magellanica is a perennial rhizomatous dioeceous herb native to Chile, Argentina and the Falkland Islands, and Andean areas of Peru, Ecuador. In the southern part of its range it grows in damper parts of the Magellanic Forests, and shrub formations on Tierra del Fuego, with an altitudinal range from sea level to 1500m.
Pinanga cattienensis is a species of small palm in the family Arecaceae. It is endemic to Vietnam, having been found in Cat Tien National Park in Đồng Nai Province, growing in seasonally-flooded tropical forest at low elevations.
Dr.Charlotte M. Taylor is a botanist and professor specialising in taxonomy and conservation. She works with the large plant family Rubiaceae, particularly found in the American tropics and in the tribes Palicoureeae and Psychotrieae. This plant family is an economically important group, as it includes plant species used to make coffee and quinine. Taylor also conducts work related to the floristics of Rubiaceae and morphological radiations of the group. Taylor has collected plant samples from many countries across the globe, including Chile, Colombia, Costa Rica, Panama, and the United States of America, and has named many new species known to science from these regions. As of 2015, Taylor has authored 278 land plant species' names, the seventh-highest number of such names authored by any female scientist.
Prunus annularis is a species of Prunus in the family Rosaceae. It is native to cloud forests along the Pacific coasts of Mexico and Central America. It is a tree 5 to 12 m tall. It is fed upon by caterpillars of the genus Oxynetra.
