Hippeastreae (Amaryllidaceae) is a controversial clade (tribe) with mainly tropical distribution (Meerow, 2010; Garcia & al., 2019). The tribe includes the genus Habranthus Herb., commonly named "rain lilies", whose species are principally distributed in South America (Arroyo, 1990;Meerow & Snijman, 1998; Howard, 2001; Amaral, 2011; Garcia & al., 2019).
Species of this genus are prized for their ornamental and phytochemical potential. Habranthus cardenasianus Traub & I.S.Nelson, is a species distributed in Bolivia and northwest Argentina and grows in sandy soils in deciduous forest (Roitman&al., 2006).
In this work, the chromosome characterization of H. cardenasianus originating from Argentina was investigated.
