Wikipedia

Sesuvium verrucosum

Sesuvium verrucosum is a species of flowering plant in the iceplant family known by the common names western sea-purslane and verrucose sea-purslane. It is native to the Americas, where it can be found in the southwestern quadrant of the United States, Mexico, and parts of South America. It grows in many types of saline and alkaline habitat types on the coast and inland, including salt marshes and other saline wetlands, alkali flats, and drying desert washes. It is a perennial herb producing many branching prostrate stems up to a metre long, forming a mat up to two metres wide. The herbage is verrucose, covered densely in crystalline bumps. The stems are lined with leaves of varying shapes which measure up to 4 cm long. Flowers occur in the leaf axils. They have no petals, but the five, pointed sepals are generally bright pink to reddish or orange in color with a thick, verrucose outer surface. At the centre of the flower is a ring of stamens around the central ovary. The fruit is a capsule about 500 mm long containing many seeds.

Notes

Comments

Sesuvium verrucosum is widespread and variable, with habitat preferences extending from coastal, saline wetlands to reservoir margins and desert alkali playas in North America and South America. Several names, including S. sessile Persoon, have been applied or misapplied to this species, which can resemble S. portulacastrum. It differs from S. portulacastrum in having sessile or occasionally pedicellate flowers and in lacking roots at stem nodes. Plants from coastal environments such as margins of estuaries are usually smaller in stature, with smaller morphological features than interior desert plants; plants at some coastal sites may function as annuals. Further investigation of this variation could provide useful insight into the relationships of different populations now assigned to S. verrucosum.
