Mimbulus mimbletonia
A not so attractive looking, but extremely rare, plant. As his interest in Herbology grew, Neville Longbottom was gifted a Mimbulus mimbletonia by his Uncle Algie. Neville demonstrated the plant's defence mechanism aboard the Hogwarts Express, leaving Harry, Ginny and Luna covered in Stinksap. For a brief time "Mimbulus mimbletonia" was a password to Gryffindor Tower - making it one of the only passwords Neville had no trouble remembering.
