Note
Four varieties of K. longifolia were recognised by Verdcourt in Fl. Trop. E. Afr. (1976). The Somali material consists of small annual plants with calyx-lobes c. 1.5 mm long and corolla-lobes 2–2.5 mm long and best agrees with var. effusa (Oliv.) Verdc.

Native to:

Angola, Kenya, KwaZulu-Natal, Madagascar, Malawi, Mozambique, Somalia, Tanzania, Zambia, Zaïre, Zimbabwe
