Kickxia spuria is a species of flowering plant in the family Plantaginaceae known by several common names, including roundleaf cancerwort{{Cite web |url=https://plants.usda.gov/java/profile?symbol=KISP |title=USDA Plants Profile |access-date=2008-05-18 |archive-date=2008-10-11 |archive-url=https://web.archive.org/web/20081011030618/http://plants.usda.gov/java/profile?symbol=KISP |url-status=live }} and round-leaved fluellen.{{BSBI 2007 |accessdate=2014-10-17 }} It is native to Europe and Asia, but it is present on other continents as an introduced species, and sometimes a noxious weed. This is a low hairy herb with a creeping stem with many branches. It produces rounded, fuzzy leaves at wide intervals along the stem, and solitary snapdragon-like flowers. Each flower is up to 1.5 centimeters long with a narrow, pointed spur extending from the back. The lobes of the mouth are yellow, white, and deep purple, and the whole flower is fuzzy to hairy. The fruit is a spherical capsule about 4 millimeters long. This species is similar to its relative, Kickxia elatine, but for the shape of its leaves, and the hairy flower stalk, which is bare with Kickxia elatine.
