“…In this context, we consider that a more extensive and detailed sampling of the genus Zamia across the Neotropics would be necessary to corroborate any correlation between trichome morphology and stem habit. REPRODUCTIVE STRUCTURES.-Although the characters employed for the identification of species of Zamia have been obtained from leaf morphology (Miquel, 1861(Miquel, , 1869Regel, 1857Regel, , 1876de Candolle, 1868;Schuster, 1932;Eckenwalder, 1980;Vovides et al, 1983;Newell, 1986;Schutzman & Vovides, 1998;Schutzman et al, 1988;Stevenson, 1993Stevenson, , 2001aStevenson, , b, 2004Nicolalde-Morejón et al, 2008), the evaluation of reproductive characters, especially those corresponding to ovulate strobili, is essential to discriminate among closely related taxa. Outstanding attributes that should be considered in this case are (i) the form and shape of the cone apex (Stevenson, 1987); (ii) the peduncle position with respect to the vertical axis of the cone, when mature (Schutzman et al, 1988); and (iii) the overall color of the cone (see descriptions and Figs.…”
