DistributionSouthern outer Coastal Plain, ranging north only to Jones County.

Coastal Plain, southeastern NC to southern FL and eastern TX.
AbundanceRare to locally uncommon over its range in NC, but can be uncommon to locally common where present. The NCNHP database has 23 records, most of which are still extant. This is a State Endangered species.
HabitatWet longleaf Pine--Wiregrass savannas and flatwoods, often over marl or coquina limestone.
PhenologyFlowering and fruiting August-October.
IdentificationStems usually are 3-6 feet tall, with lance-shaped to narrowly elliptic leaves. The whole plant is glaucescent green. The inflorescence is branched but rather narrow in outline. Each head is cylindrical, white, with 5 disk florets. When in bloom, this is one of the more striking plants of "marl savannas" in the state owing to its height and pale green foliage.
Taxonomic CommentsOlder texts treated it as Cacalia lanceolata.

Other Common Name(s)Ovateleaf Indian-plantain, Ovateleaf Cacalia, Broadleaf Indian-plantain. Websites and references use many different common names. This website will thus go with the one used by both NatureServe and Weakley (2018).
