Description

• Evolvulus cardiophyllus is a low-growing herb in the morning-glory family (Convolvulaceae). It has slender stems and small, heart-shaped to broadly oval leaves, consistent with the meaning of its scientific name (cardiophyllus, referring to heart-shaped leaves). Like other members of Evolvulus, it may produce small, five-lobed flowers, typically blue or whitish, borne singly or in small clusters. Detailed species-specific information on its appearance and life history is limited.

Range

• Evolvulus cardiophyllus is associated with Mexico and other parts of tropical America, although its precise distribution is not well documented in readily available botanical accounts. It is native to Zihuatanejo, Guerrero, and the surrounding area.

Habitat

• It is expected in warm, open habitats where low-growing herbs thrive, such as tropical scrub, dry grassland, woodland edges, and disturbed ground. Well-drained soils and seasonal rainfall may support its growth, although detailed habitat requirements for this species are not well established.
