Abstract

Abstract Chatelain, C., M. Chambouleyron, M. Charrier, J.-F. Léger & M. Perret (2021). Revision of the genus Ammodaucus (Apiaceae) in North Africa. Candollea 76: 191–200. In French, English and French abstracts. Recent collections from southern Anti-Atlas and northern oceanic Sahara identified as Ammodaucus leucotrichus Coss. & Durieu and Cuminum maroccanum Davis & Hedge (Apiaceae) led us to present a taxonomic revision of the genus Ammodaucus Coss. & Durieu in northern Africa, which is based on morphological and molecular data. Phylogenetic inferences based on original and previously published ITS ribosomal DNA sequences clearly demonstrated that Cuminum maroccanum is not related to the genus Cuminum L. but instead nested within Ammodaucus, which forms a distinct lineage in the subtribe Daucinae. Two clades within Ammodaucus are recognised. The first one includes the accessions corresponding to Cuminum maroccanum, characterized by having long bracteoles and fusiform mericarps and the second one includes the accessions corresponding to Ammodaucus leucotrichus, which displays short bracteoles and oboval mericarps. On this basis, the species Cuminum maroccanum is transferred to the genus Ammodaucus and the name Ammodaucus leucotrichus subsp. nanocarpus Beltrán-Tej. is included in the synonymy.

北非菊科(蜂科)属的修订

[摘要]查特兰，C.， M.尚布莱龙，M.查里尔，J.-F.。lsaminger & M. Perret(2021)。标题北非凤仙花属的修订。《烛台》76:191-200。法文、英文和法文摘要。最近从南反阿特拉斯和北大洋撒哈拉收集的标本被鉴定为白毛杉属。& Durieu和Cuminum maroccanum Davis & Hedge (Apiaceae)带领我们对Ammodaucus Coss属进行了分类修订。& Durieu在北非，这是基于形态学和分子数据。基于原始和先前发表的ITS核糖体DNA序列的系统发育推断清楚地表明，Cuminum maroccanum与Cuminum L.没有亲缘关系，而是嵌套在Ammodaucus中，后者在Daucinae亚部落中形成了一个独特的谱系。Ammodaucus中的两个分支已被确认。第一种属Cuminum maroccanum，具有长小苞片和梭形分片的特征;第二种属Ammodaucus leucotrichus，具有短小苞片和倒卵形分片的特征。在此基础上，本种Cuminum maroccanum被转移到Ammodaucus属，并命名为Ammodaucus leucotrichus亚种。nanocarpus Beltran-Tej。包含在同义词中。收稿日期:2021年1月11日;录用日期:2021年6月3日;首次在线发布:2021年7月7日

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.
