Salsola tuberculata sensu Aellen in Merxmüller in Prodr. Fl. Südwestafr. 32: 20 (1969) p.p., non S. tuberculata (Moq.) Fenzl. Botschantzev (1974a) included Salsola vermiformis C.A.Sm. ex Ulbr. in Engl. & Prantl in Natürl. Pflanzenfam., ed. 2, 16c: 566 (1934), nomen nudum, into synonymy of S. gemmiferum , probably based on the assumption that the taxonomic concept of S. tuberculata in Aellen (1967: 20) was misinterpreted.
