First report of plumeria rust disease caused by Coleosporium plumeriae in Taiwan.

The article discusses the first report of rust disease in Plumeria rubra, an ornamental tree, caused by Coleosporium plumeriae in Taipei, Taiwan. In December 2003, stages of a rust fungus were found on leaves of Plumeria rubra growing at the Taipei Botanical Garden. The rust generated orange to yellow sori in leaves, and, in severe infections, caused early leaf abscision. The morphology of the stages of the specimens seen on P. rubra is similar to previous descriptions of Coleosporium plumeriae.
