Dubautia laevigata is a species of Dubautia endemic to moderate elevations on the island of Kaua'i in the state of Hawaii, United States. A member of the Silversword alliance, it only grows in the understory of mesic Hawaiian tropical rainforests. It is declining in population and is threatened by the spread of invasive species, with approximately 5500 individuals remaining[1].

Description

Dubuatia laevigata is a shrub that grows up to 2.5m high with a compact woody stem. It has large, shiny green leaves 7-24cm long and 0.8-3.5cm wide. The margins of the leaves are serrate. Flowers are small (2.5-3mm long) and appear in clusters in 2-5, with yellow corollas[2]. Flowers mostly appear between December and August[3].

Distribution and Habitat

Dubuatia laevigata is only found at medium (575m-1250m) elevations in mesic wet forests on the island of Kaua'i. It is absent from the highest elevations of the Alaka'i plateau.
