Abstract

Myrsinecirrhosa Lorence & K.R.Wood (Primulaceae), a new single-island endemic shrub species from Kaua'i, Hawaiian Islands, is described and illustrated. Notes on its distribution, ecology and conservation status are included. The new species is known from an area with ca. 45 individuals, where it is restricted to the remote central windward region of Kaua'i in open bogs and along open windy ridges. Suggested IUCN Red List status is CR (Critically Endangered). It differs from its Kaua'i congeners by its longer petals and narrowly elliptic leaves with strongly undulate margins and tendril-like apex. Phylogenetic analysis using RADseq data supports the recognition of this new species.

Myrsinecirrhosa(报春花科),夏威夷群岛考艾岛的一个独特灌木新种。
Myrsinecirrhosa Lorence & K.R.Wood(报春花科)是夏威夷群岛考艾岛的一种新的单岛特有灌木物种,本报告对其进行了描述并配有插图。文章还介绍了该种的分布、生态和保护状况。据了解,该新物种产自一个约有 45 个个体的地区,局限于考艾岛偏远的中部向风地区的开阔沼泽和开阔的山脊。建议的世界自然保护联盟红色名录地位为 CR(极度濒危)。它与考艾岛同属植物的不同之处在于花瓣较长,叶片呈狭椭圆形,边缘呈强烈波状,先端呈卷须状。利用 RADseq 数据进行的系统发育分析支持对这一新种的认定。
