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
The species ranges from southern South Carolina to Georgia and southern Florida.[1]
Ecology
Habitat
Paronychia americana can occur in sandhills, sand pine scrubs, turkey oak woods, wiregrass savannas, and grassy recreation fields. [3] Associated species include sand pine, live oak, turkey oak, bluejack oak, and wiregrass. [3]
Phenology
This species flowers from June through September.[1]
Pollination
The following Hymenoptera families and species were observed visiting flowers of Paronychia americana at Archbold Biological Station: [4]
