Abstract

Abstract Lowry II, P.P., M.W. Callmander & R. Spichiger (2020). Polysciadis (Araliaceae) species nova e Madagascaria in honorem Luciani Bernardii felsinei nominata. Candollea 75: 107–114. In English, English and French abstracts. Polyscias bernardiana Lowry & Callm., an easily recognized new species from east-central Madagascar, including the Ambatovy mine site and several protected areas, is described in honor of Luciano Bernardi (1920–2001), a 20th century explorer-naturalist who has contributed more to our knowledge of Indian Ocean Araliaceae than any other botanist. This new species most closely resembles Polyscias duplicata (Thouars ex Baill.) Lowry & G.M. Plunkett from Madagascar and the Comoro Islands in forming monocaulous trees with a terminal cluster of large leaves surrounding a globose inflorescence, and in having flowers and fruits with 8–10(–12) carpels and styles, but differs in having an articulated pedicel (vs. unarticulated in P. duplicata) and lacking auxiliary leaflets (vs. a second leaflet often inserted in the axil of the main leaflets in P. duplicata). Polyscias bernardiana is illustrated by line drawings and color photos, and a risk of extinction assessment is provided based on the IUCN Red List criteria, which indicates a conservation status of “Least Concern”.

天南星科（Araliaceae）中的一个新物种Luciani Bernardii felsinei nomita

[摘要]Lowry II, p.p.， M.W. Callmander & R. Spichiger(2020)。新发马达加斯加蓼科蓼科蓼属。烛花75:107-114。英文，英文和法文摘要。多义词bernardiana Lowry & Callm。这是一种很容易识别的新物种，来自马达加斯加中东部，包括Ambatovy矿区和几个保护区，它是为了纪念Luciano Bernardi(1920-2001)而命名的。Luciano Bernardi是20世纪的探险家兼博物学家，他对我们了解印度洋五龙科的贡献比任何其他植物学家都要多。这个新种最接近于重复的多糖(千种)。来自马达加斯加和科摩罗群岛的Lowry & G.M. Plunkett，在形成单根树的过程中，有一簇顶生的大叶子围绕着一个球形的花序，花和果有8-10(-12)个心皮和花柱，但不同之处在于有一个铰接的花梗(相对于无铰接的双棱木)和缺乏辅助的小叶(相对于双棱木主小叶的叶腋上通常有第二个小叶)。用线条图和彩色照片说明，并根据世界自然保护联盟红色名录标准提供了灭绝风险评估，表明保护状态为“最不关注”。

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.
