Cycad
Ceratozamia sabatoi Vovides, Vázq.Torres, Schutzman & Iglesias
Ceratozamia sabatoi is a cycad species in the family Zamiaceae, native to northeastern Mexico, specifically the states of Hidalgo and Querétaro. It is known from only two localities, one of which is affected by agricultural and grazing activities. The species is distinguished by its flat leaflets, descending leaves, and microsporophylls with a recurved downward distal face. The specific epithet honors Sergio Sabato, a professor at the University of Naples Federico II, for his contributions to Zamiaceae biology.
Description
Ceratozamia sabatoi has a stem 8–30 cm long and 20–35 cm in diameter, with persistent, triangular cataphylls. Leaves are 3–40 in number, 60–129 cm long, and have 26–54 pairs of leaflets. Leaflets are linear, papyraceous, and flat, with green, glabrous surfaces. Pollen strobili are 11–18 cm long and 3.5–4.8 cm in diameter, with microsporophylls that have a recurved downward distal face. The species is distinguished from other Ceratozamia species by these features, particularly the microsporophyll morphology and flat leaflets. It was described in 1993 and is known from only two localities in Mexico, one of which is degraded.
