LEAFLET ANATOMY OF ZAMIA DISODON D.W. STEV. & SABATO AND Z. RESTREPOI (D.W. STEV.) A. LINDSTR.

The genus Zamia is morphologically and ecologically the most diverse of the Cycadales. Colombia is the country where most living species of Zamia have been recorded. Even though in the past this genus extended beyond the Neotropical region, nowadays it is almost entirely restricted to that biogeographical realm. As with the remaining Cycadales, this genus shows several unusual anatomical traits in the leaflets. The objective of this research was to study and compare the leaflet anatomy of Zamia disodon and Z. restrepoi and establish possible relationships between the anatomical traits and the... Mehr ...
