The type-host species of Puccinia cygnorum re-determined as Kunzea glabrescens (Myrtaceae)

摘要

Puccinia cygnorum is one of only two native Australian rusts known to occur on host plants of the family Myrtaceae. On the two collections known to have been made in Australia, including the type, the host species has been recorded as Kunzea ericifolia and K. vestita. Examination of these specimens, in the light of taxonomic revision of Kunzea, allows the re-determination of both as K. glabrescens.
