Ceratozamia
From Wikipedia, the free encyclopedia

Ceratozamia is a genus of New World cycads in the family Zamiaceae. The genus contains 16-18 currently living species and one or two fossil species. Most species are endemic to mountainous areas of Mexico, while C. robusta extends into the mountains of Guatemala 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. Many species have extremely limited ranges, and almost all described species are listed as vulnerable, endangered, or critically endangered by the IUCN Red List. Illegal plant poaching has posed a major threat to Ceratozamia species.

The plants are diecious, with a globose or cylindrical stem, rarely dichotomously branched, that may be underground or emergent. Several species produce basal shoots or suckers. The leaves are pinnately compound, straight, and spirally arranged. Leaf bases are usually deciduous but sometimes persistent. The petioles and rachis often have spines, though there may be very few to none. Leaflets are simple, entire, and articulate at the base, with parallel side veins and no distinct central vein. Male cones are cylindrical, upright, hairy, and stalked. Female cones are stalked or sessile, erect, and have short hairs. Seeds are oblong or elliptical, with a fleshy whitish outer coat.

Most species inhabit mountainous areas at 800-1000 m elevation, on sheltered slopes in moist forests. These forests range from tropical rainforests that are always wet, to pine-oak forests with alternating wet and dry seasons. There is a noticeable correlation between characteristics of species and the wetness or dryness of the habitat. Species with broad, thin leaflets live in wet habitats, and species with narrow, thick leaflets live in climates with wet and dry seasons.

No formal classification of the genus currently exists, but studies by researchers have shown that there are two major groups within the genus. The first group contains seven described species. Species in this group have small cones and thin, broad, asymmetrical leaflets that taper gradually toward the base. Species of the second group have cones that are small to large. Leaflets are narrow, thin to thick in texture, symmetrical, and do not taper toward the base. This group contains nine species.

Ceratozamia robusta is a species of plant in the Zamiaceae family. It is found in Belize, Guatemala, and Mexico. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss.

Default MAX, why doesnt RPT distinguish that on the left hand side of the pages

Its kind of confusing, it doesn't say it clearly, and say if i wanted to search just for cycads, it doesn't let me. So, maybe put a button or something for people just looking for cycads...know what i mean... i should be getting paid for that information...lol
