Puccinia malvacearum on Pelargonium geranium

It was originally found on the leaves of a species of Malva in Chile.[3] Other plants also affected by the rust include Abutilon, Alcea (Hollyhock),[4] Hibiscus, Lavatera, Malvastrum and Sphaeralcea.

Suggested control measures (in the US), include sanitation (removal or destruction of affected plants or plant portions) or treatment with fungicides.
