Syringodea is a genus endemic to South Africa in the Iridaceae family. It is very similar in appearance to the Eurasian genus Crocus and also has a stemless habit and long-tubed flowers. It is also similar to the genus Romulea. A distinguishing feature is that the ovaries are subterranean or just at the soil surface and the seed capsules remain there. It is found in both winter and summer rainfall areas and has flowers that are responsive to temperature, opening only on warm days. This genus was revised by Miriam P. de Vos in 1983
