Convolutum

Convolutum is a genus of herbaceous plants in the family Boraginaceae, commonly known as the borage family. Species within this genus are characterized by their spirally coiled flower clusters, a distinctive feature that gives the genus its name. The word "convolutum" is derived from the Latin word "convolvere," meaning "to roll up" or "to coil."

These plants typically feature rough, hairy leaves and brightly colored flowers, often blue or purple, though some species may have pink or white blooms. The flowers are usually borne in scorpioid cymes, which unfurl in a coiled manner as they develop. Convolutum species are found in various arid and semi-arid regions, particularly in the Mediterranean basin and parts of North Africa.

The exact taxonomic classification of Convolutum has seen some revision over time, with some species previously placed in other genera like Heliotropium now being included here. Research continues to clarify the relationships within the Boraginaceae family.

While not widely cultivated for ornamental purposes, some species of Convolutum have traditional uses in folk medicine in their native regions. Their ecological role often involves supporting local pollinators. The genus represents a small but distinct group of plants within the diverse Boraginaceae family, notable for its characteristic floral arrangement.
