A contribution to the rust flora (Uredinales) on Zygophylloideae (Zygophyllaceae) in Africa.

摘要

Five African species of rust fungi infecting the plant subfamily Zygophylloideae are described in detail and illustrated by line drawings, three of which are described as new: Uromyces dinteri sp. nov. (anamorph Uredo zygophylli) on Tetraena decumbens (=Zygophyllum decumbens) and on cf. Tetraena sp., Uromyces namaqualandus sp. nov. on Roepera cordifolia (=Zygophyllum cordifolium) and on cf. Roepera sp., and Uromyces paulshoekensis sp. nov. on cf. Roepera foetida (=Zygophyllum cf. meyeri=Zygophyllum foetidum). Furthermore, we examined Uromyces trollipii on Roepera foetida (=Zygophyllum foetidum) and Uredo zygophyllina (=Uredo zygophylli) on Tetraena cornuta (=Zygophyllum cornutum) and on Tetraena prismatocarpa (=Zygophyllum prismatocarpum). The description of a sixth species, Uredo augeae on Augea capensis, is added from literature.
