Evolvulus Explained

Evolvulus is a genus of flowering plants in the Convolvulaceae, the morning glory family. They are known generally as dwarf morning glories.^[1] Most are native to the Americas. There are about 100 species.^[2]

Description

These plants are annual and perennial herbs and shrubs. They have non-twining stems. The leaves have smooth edges. Flowers are borne singly or in small clusters, or sometimes in spikes. The corolla is round and flat or bell-shaped. The fruit is a capsule containing 1 to 4 seeds.^[2]

Taxonomy

Etymology

The genus name Evolvulus comes from the Latin word meaning "to unroll", inspired by its non-vining form.^[3]
