Abstract

Euryadegeneri Kobuski (Pentaphylacaceae), a dioecious shrub endemic to Kaua'i, is resurrected from synonymy with E.sandwicensis A. Gray. Euryadegeneri 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. Euryadegeneri is preliminarily designated as Critically Endangered according to the IUCN Red List guidelines.

夏威夷群岛考艾岛特有的 Euryadegeneri(五加科)复活了。
Euryadegeneri Kobuski(五加科)是考埃岛特有的雌雄异株灌木,与 E.sandwicensis A. Gray同义。Euryadegeneri 分布在考艾岛中部和西北部的山地中度至潮湿森林中。它与 E.sandwicensis 的区别在于幼茎、叶片和花梗无毛,叶片呈线状椭圆形到卵状椭圆形,花梗较长(5-11 毫米长),花瓣较短(4.5-7 毫米长)。提供了夏威夷柃属的检索表。这里指定了两个标本。根据世界自然保护联盟(IUCN)红色名录指南,Euryadegeneri 被初步定为极危物种。
