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.
