Zamia wallisii is a species of plant in the Coontie Family (Zamiaceae). It is endemic to Colombia. Its common name is chigua. [1]
Zamia wallisii was described in 1875 by Alexander Braun from material collected by Gustav Wallis in Colombia. The species was collected once again in 1888 by Guillermo Kalbreyer and then not seen again for 100 years. Both the Wallis and Kalbreyer collections were lost and no type specimen was extant resulting in some doubt about the existence of the species until its rediscovery in the 1980s, by Ian Sutherland Turner. [2] Its most noteworthy feature is its leaflets, which are up to 23.5 inches (60 centimeters) long and eleven inches (26.5 centimeters) wide, the largest of any gymnosperm. [3]
There is only one known population of this plant, comprising fewer than 50 individuals. It is located in habitat that is being consumed by deforestation. [1] Plants are found near the town of Frontino, Antioquia Department, and also near Urrao, and in Las Orquideas National Park.
Stangeria eriopus is a cycad endemic to southern Africa. It is the sole species in the genus Stangeria, most closely related to the Australian genus Bowenia, with which it forms the family Stangeriaceae.
Zamia furfuracea is a cycad endemic to southeastern Veracruz state in eastern Mexico.
Zamia pumila, commonly known as guáyara in Spanish, is a small, tough, woody cycad native to the Greater Antilles. Z. pumila was the first species described for the genus and, therefore, is the type species for the genus Zamia and the family Zamiaceae.
Zamia is a genus of cycad of the family Zamiaceae, native to North America from the United States throughout the West Indies, Central America, and South America as far south as Bolivia. The genus is considered to be the most ecologically and morphologically diverse of the cycads, and is estimated to have originated about 68.3 million years ago.
Chigua is a genus of cycads in the family Zamiaceae containing two species, endemic to small areas in northwestern Colombia. Described by botanist Dennis Stevenson in 1990, it is the most recently named genus, and the name refers to a Spanish transliteration of the common name given to cycads by the indigenous peoples of Colombia. The species are found in wet lowland rainforests at 100–200 m altitude.
Cycas aculeata is a species of cycad in the genus Cycas, native to Vietnam, where it is endemic to a single site on the south slopes of the Hai Van Pass.
Macrozamia riedlei, commonly known as a zamia or zamia palm, is a species of cycad in the plant family Zamiaceae. It is endemic to southwest Australia and often occurs in jarrah forests. It may only attain a height of half a metre or form an above trunk up to two metres with long arching fronds of a similar length. The giant cones amidst the crown of palm-like fronds contain edible seeds surrounded by red sarcotesta. The seeds are consumed by birds and animals, and can be a favoured part of the human diet when prepared correctly. M. riedlei benefits from a close association with bacteria that fix nitrogen, which also produce substances found throughout the plant that are toxic to some animals when consumed. The species is cultivated for ornamental use in urban and domestic environments.
Zamia fischeri is a species of cycad in the family Zamiaceae. It is endemic to Mexico. It is often confused with Zamia vazquezii. Zamia fischeri is named after Gustav Fischer, a cycad enthusiast of the nineteenth century.
Zamia lacandona is a species of plant in the family Zamiaceae. It is endemic to Mexico, where it occurs only in the state of Chiapas, near Palenque and Agua Azul.
Zamia lucayana is a species of plant in the family Zamiaceae. It is endemic to the Bahamas, where it occurs on southeastern Long Island near Clarence Town and Turtle Cove. It is endangered by habitat loss.
Zamia paucijuga is a species of plant in the cycad family Zamiaceae.
Zamia pseudoparasitica is a species of plant in the family Zamiaceae. It is endemic to Panama.
Zamia pygmaea is a species of plant in the family Zamiaceae found only in Cuba. It is the smallest living cycad. It is listed as critically endangered on the IUCN Red List based on its limited distribution, severely fragmented habitat, and population of less than 250 mature individuals.
Zamia roezlii is a species of cycad, a palm-like pachycaulous plant in the family Zamiaceae. It is found in Colombia and the Pacific coast of Ecuador. It is named for the Czech botanist Benedikt Roezl. A single sperm cell from Zamia roezlii is about 0.4 mm in length and is visible to the unaided eye, being the world's largest plant sperm cell. Drosophila bifurca, a species of fruit fly, has sperm that are 5.8 cm long, albeit mostly coiled tail. The tree is up to 22 feet in height with fronds up to ten feet long bearing leaflets up to twenty inches long and six inches wide.>
Gustav Wallis was a German plant collector who introduced over 1,000 plant species to Europe, many of which were named after him. He was particularly focused on orchid hunting during the Victorian orchid craze, but also was the first European collector of plants such as large-leaved Anthurium specimens that continue to be among the most sought after today.
Encephalartos latifrons is a species of cycad that is native to Eastern Cape province in South Africa at elevations of 200 and 600 metres.
Zamia erosa is a species of cycad native to the Caribbean islands of Jamaica, Cuba, and Puerto Rico, described by Orator Fuller Cook and Guy N. Collins in 1903. The species formerly known as Z. amblyphyllidia was determined in 2010 to be the same species as Z. erosa. It is listed as vulnerable by the IUCN Red List.
Encephalartos lanatus is a species of cycad, a plant belonging to the family Zamiaceae growing in Mpumalanga, South Africa. Its specific epithet, lanatus, means wooly in Latin.
Zamia incognita is a species of cycad in the family Zamiaceae. It is endemic to Colombia.
Zamia integrifolia, also known as coontie palm, is a small, tough, woody cycad native to the southeastern United States, the Bahamas, Cuba, and the Cayman Islands.
