- Note
- Verdcourt in Kew Bull. 37: 459–464 (1982), followed by Sebsebe in Kew Bull. 54: 63–79 (1999), restricted C. rhyniospermus to plants with small pale and more or less distinctly lobed corollas in Pakistan, Saudi Arabia, Egypt, Sudan, Eritrea and Somalia, whereas C. capituliferus has larger, more strongly coloured corollas that are not or only shallowly lobed, and occurs in Somalia, Ethiopia and Kenya. C. rhyniospermus is circumscribe here more broadly, as was also made by Verdcourt in Fl. Trop. E Afr. (1963).
