The variation in habit and morphology of the twelve species of Anginon, a poorly known southern African genus of woody Apiaceae, is discussed and illustrated. The genus Glia is shown to be the obvious outgroup, sharing with Anginon two convincing synapomorphies: 1, the reduction or partial reduction of the laminar part of the leaves, and 2, the heavily cutinized outer walls of the fruit epidermis. Several characters of the internal structure of the fruit, together with other morphological characters, have been analysed by the cladistic method. Our interpretation of character evolution within the genus and a first hypothesis of phylogenetic relationships, showing three distinct infrageneric groups, is presented.
