Ipomoea indica (Burman) Merrill var. acuminata (Vahl) Fosberg. Ocean-blue Morning-glory. Phen: Jan-Dec. Hab: Hammocks, coastal areas, disturbed areas. Dist: FL west to TX; West Indies, Mexico; Central and South America.
ID notes: "This species might be confused with Ipomoea purpurea and I. magnifolia but it is usually easily distinguished by the leaves grey-pubescent or tomentose beneath and the clustered flowers with very persistent bracteoles. However, it is extremely variable so leaves are sometimes glabrous, lobed or entire, bracteoles may be reduced and flowers are occasionally solitary varying in colour from blue to deep violet with prominent darker midpetaline bands." (Wood et al. 2020)
