The corolla of a Codon royenii flower has longish oblong lobes that spread somewhat above a wide, cylindrical cup. The flowers produce copious amounts of nectar, earning the plant the common name of honey bush, a name that at first glance appears totally inappropriate. But there is a pleasant surprise waiting behind the hostile-looking, spiny front!
The filaments of the flowers are fused with the floor of the yellow-green corolla cup. Cavities among the filament bases fill up with nectar secreted by glands dedicated to the pleasing of pollinators.
The valued sweet juice, stored in the cellar under the false corolla floor, is sought by the locals, from insects to people (Le Roux, et al, 2005; Leistner, (Ed.), 2000; Eliovson, 1990; iNaturalist; Wikipedia; http://pza.sanbi.org).
