Mississippi, United StatesOPGCNot Available2005COLLECTED2004Wild materialCreeping burhead is a creeping annual or short-lived perennial obligate wetland plant whose native range extends from Maryland, west to Missouri, and south to east Texas and the Florida panhandle. The leaves are basal; blades broad-ovate, 2-18 cm long, 4-16 cm wide, rounded apically, truncate to cordate at the base, with 7-9 principal veins and almost straight cross veins; leaf petioles are 10-50 cm long, enlarged and spongy below. Flowering scapes are up to 1.3 m long, upright when young, but often dropping and rooting at the nodes and tips to produce new plantlets. Flowers are perfect in whorls of 5-15 at the nodes of the arching scape, pedicellate, subtended by a triangular bract. Sepals are 5-6mm long; petals are 5-12 mm long, white, stamens 15-20; pistils many, tapered, persisting as a beak. Fruiting heads globose; achenes about 2 mm long, ribbed and beaked; seeds shiny and reticulate. Flowering occurs from June until frost.1695061NSL 440014
