Abstract

Eurya degeneri Kobuski (Pentaphylacaceae), a dioecious shrub endemic to Kaua‘i, is resurrected from synonymy with E. sandwicensis A. Gray. Eurya degeneri is distributed in montane mesic to wet forests in central and northwestern Kaua‘i. It can be distinguished from E. sandwicensis by its glabrous young stems, leaves and pedicels, linear-elliptic to ovate-elliptic leaves, longer pedicels (5–11 mm long), and shorter petals (4.5–7 mm long). A key to Hawaiian Eurya is provided. Two lectotypes are here assigned. Eurya degeneri is preliminarily designated as Critically Endangered according to the IUCN Red List guidelines.
