Notes
This species is somewhat variable, particularly with respect to the shape of the head of the buds which has been used as a key character to discriminate between groups of species. The head is generally obtuse with only slight ribs or wings, but the lobes can have bosses which in extreme forms make a distinct crown of points around the sunken apex. The extreme form, resembling the shape found in T. buvumae from the same general area, is consistent around the north and east sides of Lake Victoria, and found to a lesser extent in NE. Zaire, but var. karaguensis refers to forms with small bosses and links to normal forms on the Tanzanian side of Lake Victoria and sporadically in Zaire.
