Comments
Puccinia juncophila was described from Juncus sp. in Victoria by Cooke and Massee (1893). McAlpine (1906) examined the type material and provided an emended  description of P. juncophila, especially with regard to the size of the urediniospores. McAlpine (1906) described a second native Australian rust on Juncaceae, P. tenuispora, which occurs on Luzula spp.
