The genus Sesuvium (Aizoaceae, Sesuvioideae) in the Southern Cone

Sesuvium is a genus of 14 to 17 species of succulent plants, both annual and perennial, widely distributed in tropical and subtropical regions. The genus Sesuvium has not yet been studied in detail in the Southern Cone (Argentina, Southern Brazil, Chile, Paraguay and Uruguay), which has led to a mis...
