Geissorhiza is a large genus (103 spp.) of small to medium corm bearing plants in the Iridaceae family found in the winter rainfall region of the south and west coasts of southern Africa. Many of them make very handsome container plants and benefit from extra water during growth. Geissorhiza is quite similar to Hesperantha and superficially very difficult to tell apart although Geissorhiza blooms during the day and many Hesperantha species open late in the day. Most species of Geissorhiza have a style that divides above the anthers and in Hesperantha the style divides at the mouth of the tube. The genus Engysiphon was relegated to a section in Geissorhiza in 1985. Most of the flowers in this section have long tubes unlike the flowers in most of the other species. More information can be learned from Peter Goldblatt's monograph, 1985 and Manning, Goldblatt, Snijman, 2002. Representatives of some of the species are shown below.
