* In the ''{{Franchise/StarWars}}'' fic ''[[https://m.fanfiction.net/s/9203119/1/Encounter-On-Myrkr Encounter on Myrkr]]'' Luke Skywalker and Mara Jade try re-enacting their night on Myrkr after they’re married, while Talon Karrde is setting up a base there. They start making love in the brush and wind up contacting the stinging, itching, swelling plant from their first experience(see the Literature entry below)again. The medic says it’s the worst case he’s ever seen, over their entire bodies, and they’re forced to admit what happened. Han Solo remarks that he’d think they’d have learned their lesson about that plant the first time.

* The ''Literature/{{Twilight}}'' / ''Franchise/MarvelUniverse'' fanfic ''[[https://www.fanfiction.net/s/5482319/1/Wolverine Wolverine]]'' has Bella Logan (AKA "Wolverine") and her grandfather Victor Creed/Sabertooth reminiscing about an incident during their time with Weapon X, when they went camping with the rest of their team and one of them ran afoul of this trope.

* This is the main hazard posed by [[NamesToRunAwayFromReallyFast "Stalin's revenge"]], also known as the giant hogweed. It's a grass taller than most sapling trees. The poisonous sap/juice of this plant is really potent and causes burns comparable to mustard gas. It's also basically the Eastern European equivalent of kudzu, an imported plant that the authorities considered potentially useful but it spread uncontrollably all over the land. The worst part? It looks harmless, even beautiful, if you don't know better, as many city kids learn to their chagrin after a trip to the country. Its leaves are also broad, large, and inviting as impromptu toilet paper. Many a CitySlicker temporarily lost the ability to sit painlessly because of this plant. The stems are cylindrical and hollow and make a great pretend telescope.
%% Doesn't explain any mixup with another plant. Please do not unhide until further context has been added.* Creator/StephenKing's autobiography ''Literature/OnWriting'' has an anecdote about going to the bathroom behind a tree and using some nice shiny leaves to wipe his behind.
* Unlucky people can get the same reaction from mango peels as others do from poison ivy, because both have the same chemical called urushiol.

Note: These are generally played for laughs. If you're weak of stomach, do ''not'' Google the types of injuries these plants can create (Unless you'd really like to see an example of a blister the size of a football). Oh, and poison sumac, if burned, releases a gas that causes allergic reactions that can kill. It really pays to know your plants before you go hiking.

* In ''Manga/MonsterMusume'', protagonist Kimihito's very low on funds for food to feed his UnwantedHarem. Part of his hunt for food leads him into a forest filled with both edible plants and very poisonous ones. He was originally going to give up on the plants altogether, but SlimeGirl Suu proved she could [[NewPowersAsThePlotDemands safely distinguish between the poisonous plants and the ones that were safe to eat]].
