Description
Dubuatia laevigata is a shrub that grows up to 2.5 m (8 ft 2 in) high with a compact woody stem. It has large, shiny green leaves 7–24 cm (2.8–9.4 in) long and 0.8–3.5 cm (0.31–1.38 in) wide. The margins of the leaves are serrate. Flowers are small (2.5–3 mm (0.098–0.118 in) long) and appear in clusters of 2–5, with yellow corollas,[3] and mostly appear between December and August.[4]
Distribution and habitat
Dubuatia laevigata is only found at medium elevations of 575–1,250 m (1,886–4,101 ft) in mesic wet forests on the island of Kaua'i. It is absent from the highest elevations of the Alaka'i plateau.
