Abstract

Abstract Hopkins, H.C.F. & Y. Pillon (2020). Virotia azurea (Proteaceae: Macadamieae), a striking new species endemic to New Caledonia and notes on V. francii and V. leptophylla. In English, English and French abstracts. Candollea 75: 89–98. Virotia azurea H.C. Hopkins & Pillon (Proteaceae), the seventh species in the endemic genus Virotia L.A.S. Johnson & B.G. Briggs from New Caledonia is described and illustrated. A distribution map and preliminary conservation assessment are provided. This new species occurs principally on non-ultramafic substrates in a restricted area of central Grande Terre. It has relatively long narrow leaves, often with distally undulate-sinuate or bluntly toothed margins and a pointed apex, plus blue flowers and laterally flattened, markedly beaked fruits containing seeds with blue to mauve cotyledons. Its characters are compared with those of other species of Virotia and a key to species is provided. A handful of specimens previously identified as Virotia francii (Guillaumin) P.H. Weston & A.R. Mast are determinated mostly as Virotia leptophylla (Guillaumin) L.A.S. Johnson & B.G. Briggs and other species; the former is now confined to ultramafic substrates in southern Grande Terre and the latter is more widespread, principally occurring on non-ultramafic substrates though occasionally found on ultramafic ones in the south of the island as well.

新喀里多尼亚特有的一个引人注目的新种——蓝毒蝇(变形科:澳洲毒蝇科)及对francii和leptophyla的注解

摘要Hopkins，H.C.F.&Y.Pillon（2020）。天青病毒（变形菌科：澳洲坚果科），新喀里多尼亚特有的一个引人注目的新物种，对弗兰奇病毒和薄叶病毒有注释。英文、英文和法文摘要。Candollea 75:89-98。描述并举例说明了来自新喀里多尼亚的特有属Virotia L.A.S.Johnson&B.G.Briggs的第七个物种——Virotia azurea H.C.Hopkins&Pillon（Proteae）。提供了分布图和初步保护评估。这个新物种主要出现在Grande Terre中部限制区的非超镁铁质基底上。它有相对长而窄的叶子，通常有远端波状的具正弦或钝齿的边缘和尖的先端，加上蓝色的花和侧面扁平的、明显有喙的果实，果实中含有蓝色至淡紫色子叶的种子。将其特征与其他种类的紫苏进行了比较，并提供了一个物种的关键。少数先前被鉴定为弗氏病毒（Guillaumen）P.H.Weston&A.R.Mast的标本主要被确定为细叶病毒（Guiliaumen）L.A.S.Johnson&B.G.Briggs和其他物种；前者现在仅限于Grande Terre南部的超镁铁质基底，后者更为广泛，主要发生在非超镁铁质基质上，尽管偶尔也会在该岛南部的超级镁铁质基底上发现。

期刊介绍： Candollea is an international peer-reviewed journal that publishes original scientific papers, preferably in English but also in French. Spanish language manuscripts will be evaluated only if linked to scientific projects involving the Conservatoire et Jardin botaniques de Genève. Successful submissions will be in the fields of evolution, molecular systematics, morphology-anatomy, nomenclature, taxonomy, or vegetation analyses of plants. Reviews and articles on the history of botanical collections are welcome. New distribution records lacking pertinent analyses will not be considered. Manuscripts dealing with nomenclature alone will be considered only if clearly related to the Geneva library or herbarium (G). Authors are encouraged to deposit duplicates of their material, especially nomenclatural types, at G.
