| Abstract: | Puccinia erythropus, whose uredinial-telial stage occurs onMiscanthus andEularia spp. (Gramineae), was found to have a heteroecious macrocyclic life cycle with the spermogonial-aecial stage onCynanchum sublanceolatum var.obtusum (Asclepiadaceae).Puccinia miyoshiana, which forms the uredinial-telial stage onBothriochloa, Capillipedium, Eccoilopus, andSpodiopogon (Gramineae), is known to form its spermogonial-aecial stage onBuplerum spp. (Umbelliferae). By field observations and artificial inoculations,Bupleurum komarovianum was proved to serve as an additional spermgonial-aecial host of this fungus. |
