Abatia

Abatia (syn. "Raleighia" Gardner) is a genus of about ten species of Central and South American trees in the willow family Salicaceae (following the Angiosperm Phylogeny Group classification). Previously it was treated in the family Flacourtiaceae, or tribe Abatieae of the family Passifloraceae (Lemke 1988) or Samydaceae by G. Bentham & J.D. Hooker and Hutchinson.
"Abatia" has opposite leaves with very small stipules and marginal glands at the base of the blade of the leaf. The valvate (meeting at the edges without overlapping) perianth (sepal and petal together) members are closely joined at the base. They bear many filamentous processes.
The leaves of "A. rugosa" and "A. parviflora" are source of black dye in Peru.
