Sphenoclea zeylanica, called chickenspike, gooseweed, and wedgewort, is a widespread species of flowering plant in the genus Sphenoclea, native to Africa, Madagascar, tropical and subtropical Asia, and Australia.[3] It is widely introduced in the New World tropics and subtopics from the southern United States to northern Argentina.[2] Its young leaves are edible and are occasionally eaten, perhaps with a light boiling.[3] A common weed of rice paddies, it can cause yield losses from 25 to 50%.[4]
