Common name: Spotted sandmat
Synonyms: Chamaesyce maculata (Linnaeus) Small; Euphorbia supina Rafinesque.
Euphorbia maculata is a weedy annual herbaceous plant. It tends to grow low to the ground and somewhat repent.
This plant is native from Quebec to North Dakota and south to Florida and Texas. However, it has been introduced globally.
E. maculata prefers moist to wet sandy soils like alluvial sands, moist loamy or clayey sand, and coarse calcareous gravelly soils. It is found in a variety of natural and disturbed community types, including pine flatwoods, sand dunes, river banks, open shorelines, and near brackish marshes. Disturbed habitat includes railways, citrus furrows, cracks in pavement, roadside ditches, and recently clear-cut, site prepared and planted slash pine flatwoods.
It has been observed flowering and fruiting in September.
Herbivory and toxicology
Euphorbia maculata has been observed to host plant bugs from the Miridae family such as Lygus lineolaris, Semium hirtum and Spanagonicus albofasciatus.
Conservation, cultivation, and restoration
Medicinally, the sap can be ingested to induce vomiting and act as a laxative, and can be used topically to treat warts, sores, lesions, and soreness.
