Ceratozamia hildae G.P.Landry & M.C.Wilson
Natives of Mexico (and now critically endangered there due to habitat loss), bamboo cycads don’t look very much like most other cycads. They come from a deciduous cloud forest around San Luis Potosi and Quiretaro in eastern Mexico, between elevations of 2953-3937' (900-1200 m). They are not found in the wild in the United States, but they are fairly common in gardens.
Identification: These cycads grow up to 4' (1.2 m) high. Male cones are up to 12" (30 cm) in length x 1½" (3.8 cm) around and yellowish brown; female cones are somewhat shorter and wider, nearly cylindrical, and olive green. Each stem is up to 4' (1.2 m) long, with 20-50 leaflets. Each leaflet is 4-10" (10-25 cm) long.
