Chigua (genus)
Chigua was formerly recognized as a genus of cycads in the family Zamiaceae containing two species described in 1990. It was re-described as a single species in the genus Zamia in 2009.
The scholarly use of Chigua for a cycad was first applied to a plant collected in 1918 by Francis W. Pennell in northern Colombia. The Type was not reported again until re-located by Rogrigo Bernal in 1986. Dennis Stevenson described the genus and two species, C. restrepoi and C. bernalii, in 1990. It was recognized that Chigua was very closely related to Zamia and might indeed be nested in Zamia.[1]
Anders Lindström reclassified C. restrepoi as Z. restrepoi and C. bernalii as a synonym of Z. restrepoi in 2009.[2][3]
