Dianella lignosa (Asphodelaceae), a new species from the north-west Kimberley region of Western Australia

Abstract

We here describe Dianella lignosa R.L.Barrett & M.D.Barrett (Asphodelaceae) as a new species from the Kimberley region of Western Australia, previously included under Dianella longifolia R.Br. The new species is readily identifiable by its thick, woody lateral rhizomes, and also differs from D. longifolia in leaf and floral characters.
