Chenopodium hoggarense (Amaranthaceae), a new species from Algeria and Chad
Abstract: Chenopodium hoggarense Uotila & C. Chatel., a new species of the family Amaranthaceae s.l. (Chenopodiaceae s.str.) from the Hoggar and Tibesti mountains of the Sahara, in Algeria and Chad, is described and illustrated. The species was found in quantities from the Hoggar (Ahaggar) mountains in 2019. It had been observed there earlier several times, but it was confused with C. vulvaria L. because of its similar smell and dense cover of vesicular hairs. However, it differs from C. vulvaria in growth habit, leaf shape and flower characters. Its relationships to and the identity of C. vulvaria var. incisum Maire are discussed and var. incisum is lectotypified. Chenopodium hoggarense is known only from the isolated Hoggar and Tibesti mountains. Citation: Chatelain C., Uotila P., Benhouhou S., Mombrial F., Mesbah M., Baa S. & Benghanem A.

期刊介绍：
Willdenowia is an international peer-reviewed journal publishing original research articles in English from the entire fields of plant, algal and fungal systematics, covering the evolution, taxonomy and nomenclature of these organisms as well as related fields such as floristics and plant geography. Articles on phylogeny and molecular systematics are especially welcome, as are review articles. Descriptions of new taxa may be considered, but only if supported by robust evidence. Narrowly regional studies of widespread taxa, routine typifications, checklists and new floristic records are generally not considered (excluding contributions to the Euro+Med-Checklist Notulae). Authors are encouraged to deposit duplicates of their material, especially nomenclatural types, in the Berlin herbarium (B).
