Abstract
This paper describes four new species of rust fungi from southern Africa. Three of them, Puccinia dimorphothecae-cuneatae on Dimorphotheca cuneata (Asteraceae), P. feliciicola on Felicia filifolia (Asteraceae), and Uredo myricae on Myrica sp. (Myricaceae), were collected in the South African Cape region, while Uromyces hessii on Zantedeschia angustiloba (Araceae) is from Angola. Rust fungi are reported for the first time on the plant genera Thereianthus (Iridaceae) and Cullumia (Asteraceae), both from South Africa. The specimen on Thereianthus was provisionally determined as Uromyces ecklonii that has been known so far only on Freesia. The rust of Cullumia showed only uredinia that were similar to Puccinia clanwilliamensis, hitherto only known on Berkheya.
