Abstract
The two rust fungi, Ravenelia acaciae-arabicae and R. evansii, were both found on Acacia nilotica subsp. indica in southern (Tamil Nadu) and northern (Gujarat) India. R. acaciae-arabicae has been often incorrectly synonymised with R. evansii, although each has distinctive urediniospores, viz. echinulate in R. acaciae-arabicae and verruculose in R. evansii. Both species are re-described and illustrated from fresh specimens collected in India. Herbarium specimens of R. evansii from South Africa, including the holotype, were also examined. The difficulty in connecting different anamorphic spore stages to either of these teleomorphic rusts is highlighted by the presence of similar aecidia on plants of A. robusta infected with R. evansii in South Africa and on A. nilotica subsp. indica infected
with R. acaciae-arabicae in India. It is not known whether these aecidial rusts represent the same species, nor is it known if they represent an aecidial stage of either R. acaciae-arabicae, R. evansii or
other rusts.
