The image presents a close-up view of the underside of leaves from cut-leaved evening primrose (Oenothera laciniata) plants, showcasing the effects of rust fungus infection.

**Leaf Appearance**

* The leaves exhibit a yellowish-green color with serrated edges.
* They display numerous small, orange-yellow pustules on their undersides, which are characteristic of rust fungi.

**Rust Fungus Identification**
