Tritonia securigera subsp. securigera, in Afrikaans the tandkalkoentjie (little tooth turkey), has a prominent tall yellow protuberance on each of the three lower tepals. These obstacles can only be cleared by nectar-seeking bees by loading pollen from the anthers onto their backs for unloading at the next flower. The three yellow “teeth” can be seen in these flowers photographed near Oudtshoorn. So can the oblong purple anthers at the tops of the two visible stamens and the taller style with its three-branched stigma under the hooded dorsal tepal. The bright orange flowers of about 2 cm in diameter appear in spring.
The plant grows annually from a corm to heights ranging from 15 cm to 40 cm. The leaves are sword-shaped and may be crisped. The plants are distributed more widely than the Little Karoo, from west of Riversdale to Graaff-Reinet (Vlok and Schutte-Vlok, 2010; Manning, 2009).
