一般资料:
This species was first described as a wholy seperate, and new genus (Chigua) in 1990. Considered sister to both Zamia and Microcycas. New research, using DNA analysis, now places Chigua paraphyletic with Zamia (K. D. Hill et al. THE FAMILIES AND GENERA OF CYCADS: A MOLECULAR PHYLOGENETIC ANALYSIS OF CYCADOPHYTA BASED ON NUCLEAR AND PLASTID DNA SEQUENCES, Int. J. Plant Sci. 164(6):933-948. 2003). In this study Chigua is clearly nested within Zamia, but Microcycas remains as sister group.
