Dubautia kenwoodii G. Carr

Dubautia kenwoodii is a small shrub about 5 dm tall; the leaves are opposite.   Diagnostic features of the species include the combination of uniseriate, peripheral, very firmly coalescent receptacular bracts, cymose-glomerate capitula, and coriaceous, lustrous leaves with sharply cartilaginous-toothed margins and abruptly narrowed, broadly clasping bases. Based on the single known collection, flowering appears to occur in June.

This species of the Hawaiian silversword alliance is known only from the Holotype, collected on the rim of Kalalau Valley, N of Kahuama'a Flat, Kaua'i.  Its habitat is a steep, diverse Lowland Mesic Forest at 800 m elevation.
