Table 1. Comparison of Sansevieria chlorantha M.Burkart, Kavula, Sikawa & Yinger sp. nov. with similar species of the subgenus Sansevieria. The traits of the species compared are taken from the protologues (Brown 1915; Newton 2015; Webb & Newton 2018), either directly or in a few cases from the pictures within.
