Ink painting/drawing of linseed rust, caused by Melampsora lini.

The painting shows a linseed stem with two offshoots. The central shoot terminates in two seedpods, whereas the side shoots terminate in seed buds or blue five-petalled linseed flowers. There are yellow, chlorotic areas painted on the leaves, with orange dots representing the rust pustules. Rust pustules are also present on the seed heads.
