摘要

Wege, J.A. & Thiele, K.R. Two new species of Hibbertia (Dilleniaceae) From near Ravensthorpe in Western Australia. Nuytsia 19(2): 303-310 (2009). Two new and geographically restricted species allied to Hibbertia hamulosa J.R.Wheeler and H. mucronata (Turcz.) Benth. are newly described. Hibbertia abyssa Wege & K.R.Thiele is distinctive for its long, slender and more or less glabrous peduncles, and sepals with both uncinate and Minute stellate hairs on the Outer Surface. This species, which occurs on shallow soils with siltstone outcropping, is known from a single population adjacent to the nickel mine on Bandalup Hill and has recently been nominated for listing as Declared Rare Flora. Hibbertia atrichosepala Wege & K.R.Thiele is readily distinguished from allied species by its completely glabrous sepals. It is a narrow-range endemic of rocky, lateritic habitats in the Ravensthorpe Range and is listed as having Priority One conservation status.

Wheeler和H. mucronata(Turcz。)Benth结盟。是新描述的。 Hibbertia abyssa Wege&K.R. Thiele的特点是长而纤细,或多或少是无毛的花序梗,并且萼片的外表面有不合星状和微小星状的毛。该物种存在于粉砂岩露头的浅层土壤中,是从班达卢普山镍矿附近的一个种群中得知的,最近被提名为申报稀有植物群。 Hibbertia atrichosepala Wege和K.R. Thiele的完全无毛的萼片很容易将其与盟友物种区分开。它是Ravensthorpe山脉中岩石,红土生境的狭义地方特有物种,被列为一级优先保护地。
