Abstract:

A new variety, Ardisia lindleyana var. angustifolia C. M. Hu & X. J. Ma is described. It differs from the type variety by its leaves being linear-lanceolate, 7-13.5 cm long, only 4-7 mm broad. Superficially, it strikingly resembles A. ensifolia E. Walker and A. quinquegona Blume var. salicifolia (E. Walker) C. M. Hu & J. E. Vidal, but can be easily distinguished by its rusty puberulent branchlets, inflorescences terminal on leafy branchlets, and leaves with marginal glands.
