Abstract Jacquemoud, F. & D. Jordan (2020). Androsace albimontana (Primulaceae): a new species from the Alps (France, Switzerland, Italy) to be distinguished from A. pubescens. Candollea 75: 149–155. In French, English and French abstracts. A new alpine species of the genus Androsace L. (Primulaceae), Androsace albimontana D. Jord. & Jacquemoud is described. Specimens attributed to the new taxon were until now considered by floras as being part of the high morphological and ecological variability of Androsace pubescens DC. (bi- to trifurcate vs simple trichomes, corolla mostly pink to rarely white vs white; acid, siliceous vs alkaline, calcareous substrate), a chasmophytic species growing exclusively on limestone cliffs. Morphology, habitat and ecology of the new taxon were determined in the siliceous mountain ranges of Aiguilles Rouges and Mont-Blanc (Haute-Savoie, France), and in Valais (Switzerland). Data from Italy (Monte Rosa, Valle d'Aosta, Piemonte) only provided by floras or botanical literature, will have to be subject of further field and herbarium studies. Distribution data are given, relationships with other species of Androsace subsect. Aretia (L.) Kress and the putative origin of the new taxon are discussed.

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”.
[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”。

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.

Abstract Randriarisoa, A., Y. Naciri & L. Gautier (2020). Labramia ambondrombeensis (Sapotaceae), a Critically Endangered new species from Madagascar. Candollea 75: 83–87. In English, English and French abstracts. Timber of the family Sapotaceae are appreciated for their physical properties internationally as well as locally, which often put a serious pressure on species survival. Taxonomic efforts are badly needed before producing reliable conservation assessments for the Malagasy species. In the framework of the revision of three related Sapotaceae genera, all endemic from Madagascar and surrounding islands of the Western Indian Ocean, a new species of Labramia A. DC. has been identified. It is described and illustrated here. Labramia ambondrombeensis L. Gaut. & Randriarisoa is one of the two Labramia species that have relatively small leaves. It is compared to Labramia platanoides Capuron ex Aubrév., the other small-leaved species from which it differs in leaf shape, pedicel size and ovary cell number. Labramia ambondrombeensis is known from a single collection that comes from a littoral forest in the Northeastern coast of the island, lacking any legal protection and is preliminary assessed as “Critically Endangered” using the IUCN Red List Criteria.
摘要Randriarisoa，A.，Y.Naciri和L.Gautier（2020）。Ambondromeensis（皂科），马达加斯加一个极度濒危的新种。Candollea 75:83-87。英文、英文和法文摘要。皂科木材因其物理特性而受到国际和当地的赞赏，这往往给物种的生存带来严重压力。在对马达加斯加物种进行可靠的保护评估之前，迫切需要进行分类学研究。在修订三个相关的皂科属的框架内，所有属都是马达加斯加和西印度洋周边岛屿的特有种，是Labramia a.DC的一个新种。已确认。这里对其进行了描述和说明。琥珀蓝Randriarisoa是两个叶片相对较小的Labramia物种之一。将其与Labramia platanoides Capuron ex Aubrév.进行比较。，其他小叶种，在叶形、蒂大小和子房细胞数量上与之不同。Ambondromeensis是从该岛东北海岸的一个沿海森林中采集的一个物种，缺乏任何法律保护，根据国际自然保护联盟红色名录标准，该物种被初步评估为“极度濒危”。

Abstract Callmander, M.W., R. Razakamalala, I. Luino, R.L. Andriamarisoa & S. BUERKI (2020). Novelties from the Northern Mountains Complex of Madagascar V: A new threatened Pandanus (Pandanaceae) from the Kalobinono massif. Candollea 75: 99–105. In English, English and French abstracts. A new species of Pandanus Parkinson (Pandanaceae) endemic to Madagascar is described as Pandanus kalobinonensis Callm., Razakamal. & Luino and illustrations are provided. The new species is restricted to the north-western lowland moist evergreen forests of the Kalobinono massif. Pandanus kalobinonensis can easily be morphologically distinguished from other members of the genus by its small solitary globose syncarp borne on a short peduncle, monocarpellate drupes, and single spiniform stigma with an adaxial stigmatic groove. Despite the occurrence of both collections within limits of the newly designated Galoko-Kalobonino Protected Area, the new species is preliminary assessed as “Endangered” [EN] using the IUCN Red List Criteria.

Despite the occurrence of both collections within limits of the newly designated Galoko-Kalobonino Protected Area, the new species is preliminary assessed as “Endangered” [EN] using the IUCN Red List Criteria.","PeriodicalId":55276,"journal":{"name":"Candollea","volume":"75 1","pages":"105 - 99"},"PeriodicalIF":0.6,"publicationDate":"2020-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41594759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abstract Atalahy, A.M., F. Rakotonasolo, S. Andriambololonera, M. Rabarimanarivo, H.L. Ranarijaona & S.G. Razafimandimbison (2020). A new name in the Malagasy tribe Vanguerieae (Rubiaceae). Candollea 75: 71–73. In French, English and French abstracts. A variety of the Malagasy genus Canthium Lam. (Rubiaceae, Vanguerieae), Canthium perrieri var. louvelii Cavaco, is transferred to the genus Pyrostria Comm. ex Juss. because, like the typical variety already transferred in this genus, it shares its distinctive characters (inflorescences or solitary flowers involucrate). This taxon is further raised to species level, as it is morphologically distinct from Pyrostria perrieri (Cavaco) Razafim. et al. We provide the necessary new replacement name: Pyrostria orientalis A. Atalahy, Rakotanas. & Razafim., since the epithet louvelii is already occupied in Pyrostria.
Atalahy, a.m.， F. Rakotonasolo, S. Andriambololonera, M. Rabarimanarivo, H.L. Ranarijaona & S.G. Razafimandimbison(2020)。马达加斯加族的新名称。Candollea 75: 71-73。法文、英文和法文摘要。马达加斯加樟子树属的一个变种。(Rubiaceae, Vanguerieae)， Canthium perrieri var. louvelii Cavaco，被转移到Pyrostria com . ex Juss属。因为，像这个属中已经转移的典型品种一样，它具有其独特的特征(花序或单生花总苞)。该分类群进一步上升到种的水平，因为它在形态上不同于Pyrostria perrieri (Cavaco) Razafim。et al。我们提供必要的新替代名称:Pyrostria orientalis A. Atalahy, Rakotanas。& Razafim。因为在Pyrostria中已经有了louvelii这个词。
