Phyla nodiflora (frog fruit, sawtooth fogfruit, turkey tangle), is an ornamental plant in the Verbenaceae family, and is native to South America and the United States. It can be found in tropical areas around the globe, a naturalized species in many places. This plant is cited in Flora Brasiliensis by Carl Friedrich Philipp von Martius. It is often grown as groundcover, and is sometimes present in yards as a lawn weed.
The inflorescence consists of a purple centre encircled by small white-to-pink flowers. The flower takes on a match-like look, which is why the plant is sometimes called matchweed.
