Morphology
Like most representatives of the genus, this plant is characterized by fleshy succulent leaves and stems that serve as a reservoir for storing water. This anatomical feature ensures survival during periods of drought and in regions with uneven rainfall distribution.
The flowers have a structure typical of purslanes and open mainly in sunny weather. The specific epithet "macrantha" points to the relatively large size of the flowers compared to some related species.
Interesting facts
The geographical footprint of this species is exceptionally broad for a single plant taxon. In the Old World, it is documented in Greece, Italy, Spain, Belgium, Morocco, Tunisia, and Liberia, as well as on islands like Sicily and Rhodes.
In the Americas, its native or introduced range covers numerous distinct ecological zones. It can be found in the United States from California to Florida, and stretches southward through Mexico into Guatemala.
