Sagittaria papillosa, the nipplebract arrowhead,[2] is a plant species native to the south-central United States (Texas, Oklahoma, Louisiana, Arkansas and Mississippi).[3][4]

Sagittaria papillosa grows in wet places such as marshes and the banks of lakes and slow-moving streams. It is a perennial herb up to 120 cm tall. Petioles are triangular in cross-section, the leaf blade very narrowly elliptical to ovate, not lobed. The species is distinguished from others in the genus by having bumps (papillae) resembling nipples on the flower bracts.[4][5][6][7]
