Narrow Leaved Bindweed Convolvulus lineatus L. is a perennial plant in the family Convolvulaceae. The native range of the species is Mediterranean to western Mongolia and Pakistan. In Italy it is present in the central and southern regions (except for Molise and Basilicata), in Sicily and in Sardinia. In the past it was also recorded in eastern Liguria.
It is generally 3-15 cm tall and has twisted, creeping stems with woody base. Leaves are linear and silvery sericeous. Flowers develop between March and June, and have funnel-shaped corollas, white to pale pink.
Narrow Leaved Bindweed is very rare in Lazio and occurs in coastal areas around Rome (Santa Marinella; in the past also Anzio, Civitavecchia, Santa Severa) and on the islands of Ventotene and Santo Stefano, where it grows in dry grasslands and open areas with sparse vegetation.
