Description
A description of Paronychia americana is provided in The Flora of North America.
P. americana is a sprawling, ascending, or erect annual. Leaves are elliptic or spatulate, 4-18 mm long, and 1-2.5 mm wide, with usually conspicuous stipules. The calyx is purple with a pubescent and globose tube. The tube is 0.5 mm long with 0.5 mm long calyx lobes. The sepals are white-scarious-margined, broadly rounded, and hooded. There is a densely pubescent on the basal portion of the sepals and this portion is nearly ½ its length. The stem is glabrous or has one side with curly hairs.[1][2]
Distribution
Paronychia americana is endemic to an area from southern South Carolina to peninsular Florida, but the majority is found in Florida.[3]
