The Cycadales are a group of significant global conservation concern and have the highest extinction risk all seed plants. Understanding synchronisation reproductive phenology may be useful for by enabling targeting pollen collection from wild populations identifying window fertilisation to aid in cultivation Cycadales. Phenological data 11 species Zamia were gathered herbarium specimens. Four phenological characters coded with monthly character states. DNA was isolated sequenced 26S, CAB, NEEDLY, matK rbcL, simultaneous phylogenetic analysis sequence carried out. Three major clades recovered: Caribbean clade, Central American clade South clade. Eight showed statistically microsporangiate ovulate phases, indicating time fertilisation. Close consistently observed throughout (statistically four five species) but less consistent one two three species). Ultimately, is shown potential driver speciation some others barrier hybridisation.
