Evolvulus alsinoides

Evolvulus alsinoides, commonly known as dwarf morning-glory and slender dwarf morning-glory, is flowering plant from the family Convolvulaceae. It has a natural pantropical distribution encompassing tropical and warm-temperate regions of Australasia, Indomalaya, Polynesia, Sub-Saharan Africa and the Americas.

It was first described in 1753 by Carl Linnaeus as Convolvulus alsinoides. In 1762, he transferred it to the new genus, Evolvulus.

Description
It is a herbaceous plant, annual or perennial with numerous prostrate or ascending stems, slender, with appressed and spreading hairs. The leaves, petiolate or subsessile, are 0.7 to 2.5 cm long and 5 to 10 mm long.

The rounded corolla, with pentameric symmetry, blue in color, rarely white, is 7 to 10 mm in diameter. The stamens, with filiform filaments, are united at the base of the corolla tube. The ovary, glabrous, is surmounted by two free styles. The fruit is a globular capsule, with four valves, generally containing four seeds that are black and smooth.

Chemical compounds isolated from E. alsinoides include scopoletin, umbelliferone, scopolin and 2-methyl-1,2,3,4-butanetetrol.
