|discussion=<p>Species 100 (7 in the flora).</p><!--
--><p>Most species of Hypoxis are in southern Africa. The key to flowering plants presented below will work for most specimens; some specimens have intermediate characteristics and are impossible to identify without seeds. When mature seeds are available, identifications should be confirmed by examination of the seed characters. Relationships among the species in the flora are uncertain and will remain so until a better understanding of the primarily African H. angustifolia complex is reached. Therefore, species are treated here in alphabetical order.</p>
