Ceratozamia microstrobila is a species of plant in the family Zamiaceae. [3]
Ceratozamia microstrobila has small glossy green leaves that are about 70 centimeters long. The new leaves of this plant take the color of bronze to darker brown. The plant produces small pollen cones. These cones have the color of yellowish green. [4]
The plant is endemic to Mexico, within the state of San Luis Potosí and in the southern portion of Tamaulipas. [1] It is native to a terrestrial environment that includes deciduous cloud forests and oak woods on limestone. [1] It is found on Ejido las Abridas mountain in the Sierra Madre Oriental of San Luis Potosí State, and the very southern portion of Tamaulipas. There are at least 6 wild populations.
This species likes a well shaded area that is well drained. [5]
It is threatened by habitat loss. It is recorded to be vulnerable to becoming an endangered species due to the decrease in population. In the past fifty years, the population of this Ceratozamia microstrobila has decreased between 30 and 50 percent.
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.
Cupressus arizonica, the Arizona cypress, is a North American species of tree in the cypress family Cupressaceae, native to the southwestern United States and Mexico. Populations may be scattered rather than in large, dense stands.
Ceratozamia is a genus of New World cycads in the family Zamiaceae. The genus contains 27 known currently living species and one or two fossil species. Most species are endemic to mountainous areas of Mexico, while few species extend into the mountains of Guatemala, Honduras and Belize. The genus name comes from the Greek ceras, meaning horn, which refers to the paired, spreading horny projections on the male and female sporophylls of all species.
Cycas beddomei is a species of cycad in the genus Cycas, native to India, where it is confined to a small area of Andhra Pradesh state in the Tirumala Hills in scrubland and brush covered hills.
Ariocarpus agavoides is a species of cactus. It is endemic to Mexico. It grows in dry shrubland in rocky calcareous substrates. Some taxonomists place it in a separate genus as Neogomezia agavoides. The locals use the slime from the roots of the plants as glue to repair pottery. The sweet-tasting warts are eaten and often added to salads
Ceratozamia hildae, commonly known as the bamboo cycad, is a species of cycad in the family Zamiaceae that is endemic to Mexico. It is native to the Huasteca Potosina of Querétaro and San Luis Potosí, near the Santa Maria River. C. hildae inhabits deciduous oak woodlands at elevations of 850–1,300 m (2,790–4,270 ft). It is threatened by habitat loss and over-collecting.
Ceratozamia kuesteriana is a species of cycad in the family Zamiaceae that is endemic to the Sierra Madre Oriental of Mexico.
Ceratozamia latifolia is a species of cycad in the family Zamiaceae that is endemic to Querétaro, Hidalgo and San Luis Potosí in Mexico. It inhabits cloud zone oak forests in the Sierra Madre Oriental.
Ceratozamia mexicana is a species of plant in the family Zamiaceae.
Ceratozamia whitelockiana is a species of plant in the family Zamiaceae. It is endemic to Mexico, where it is known only from Metates and Chiapan in Oaxaca state. Only two subpopulations have been found, with a total population of about 2200 individuals. The habitat is threatened by conversion to plantations using slash-and-burn techniques.
Ceratozamia zaragozae is a species of plant in the family Zamiaceae. It is endemic to the Rio Verde in El Capulín, San Luis Potosí state in northeastern Mexico. It is a Critically endangered species, threatened by habitat loss. It is found southwest of the Rio Verde, in Capulin district.
Macrozamia glaucophylla is a species of cycad from the genus Macrozamia and the family Zamiaceae. Endemic to New South Wales, Australia, this species has features that resembles palms, although both species are taxonomically quite different. The current population trend of Macrozamia glaucophylla is stable with 2,500 to 10,000 mature individuals. The species are found in several habitats including forest and savanna. Ecologically, Macrozamia glaucophylla lives in terrestrial system, a land-based community of organisms where the biotic and abiotic components interact in the given area.
Macrozamia miquelii, is a species of cycad in the plant family Zamiaceae. It is endemic to Queensland and New South Wales in Eastern Australia. Located within sclerophyll forests dominated by eucalyptus trees, the cycad grows on nutrient-poor soils. It is recognised within the Zamiaceae family for its, medium height at 1 m, intermediate size of male and female cones and lighter green leaves compared to other cycads within the plant family of Zamiaceae. The seeds have an orange red sarcotesta which attracts fauna consumption, allowing a mutualistic seed dispersal for the cycad. These seeds are also edible for human consumption if prepared correctly to remove the toxins.
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.
Encephalartos caffer, the Eastern Cape dwarf cycad, is a rare cycad from the genus Encephalartos. It typically has an underground stem, with a small portion on top, the stem is only very rarely branched and may be as much as 40 cm long. Emerging from the top are long, pinnate, dark green leaves up to 1 metre (3.3 ft) long. These often have a distinctive ruffled, feathery appearance, caused by the numerous, clustered leaflets being irregularly twisted from the central stalk and pointing out in different directions. New leaves are brown and woolly at first but most of the hair is lost as they mature, although they never become completely smooth or glossy. Both male and female plants bear single reproductive cones made up of a series of spiraled scales, which become greenish-yellow when mature. In the female, two largish, glossy, scarlet-coloured seeds are formed on top of each cone scale.
Encephalartos lebomboensis is a species of cycad in the family Zamiaceae. Native to the Lebombo Mountains of South Africa, the species was first described in 1949 by the South African botanist Inez Verdoorn. It is commonly known as the Lebombo cycad, although the name is also used for Encephalartos senticosus which also occurs in the same locality.
Encephalartos senticosus is a species of cycad in the family Zamiaceae native to the Lebombo Mountains of Mozambique, Eswatini (Swaziland), and the KwaZulu-Natal province of South Africa. Prior to its description in 1996, Encephalartos senticosus had been confused with the closely related and sympatric Encephalartos lebomboensis. Both species are commonly known as the Lebombo cycad.
Encephalartos whitelockii is a species of cycad that is native to Uganda.
Encephalartos natalensis, the Natal cycad or giant cycad, is a species of cycad that is endemic to the Qumbu and Tabankulu areas of the northern part of the Eastern Cape, and through most of KwaZulu-Natal. The number of mature individuals of this species is declining and the International Union for Conservation of Nature has assessed its conservation status as being "near threatened".
Encephalartos aemulans, the Ngotshe cycad, is a species of cycad endemic to South Africa. It is listed by the IUCN as Critically Endangered and by CITES in Appendix I. Only 100-250 are believed to be left, with a decreasing population trend. Its main threat is collecting of wild specimens.
