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]
Ecology
Habitat
Paronychia americana can occur in sandhills, sand pine scrubs, turkey oak woods, wiregrass savannas, and grassy recreation fields. [4] Associated species include sand pine, live oak, turkey oak, bluejack oak, and wiregrass. [4]
Phenology
This species flowers from June through September.[1]
Pollination
Paronychia americana has been observed at the Archbold Biological Station to host sweat bees from the Halictidae family such as Lasioglossum nymphalis and L. placidensis and wasps from the Vespidae family such as Leptochilus krombeini.[5]
