Alyssum polyodon Boiss. & Buhse 1860

Alyssum polyodon Boiss. & Buhse in Nouv. Mém. Soc. Imp. Naturalistes Moscou 12: 17. 1860. Type: “In Weingärten der Stadt Eriwan, [Buhse] 15 April 1847 (florens). Bei Tassakend und Sisian, 23 Mai 1847 (florens et defloratum) [Buhse] No 69”. Lectotypus (designated here): UZBEKISTAN: “Tassakend”, s.d., Buhse s.n. (G-BOIS [G00332409]; isolecto-: LE [n.v.]). Notes. – The lectotype has Boissier’s annotation of the species name, and the other Buhse syntypes were not located in G-BOIS or in the other Geneva herbaria. This species name was reduced by Boissier in Flora Orientalis to a synonym of A. campestre var. micropetalum (Fisch.) Boiss. However, this varietal name was synonymized by DUDLEY (1965b: 381) under A. minus (L.) Rothm. Although both names are synonyms of A. simplex Rudolphi (in J. Bot. (Schrader) 1799(2): 290. 1799), the lectotype is a flowering branch quite different morphologically from plants of A. simplex. The name A. polyodon was not listed in BUSCH (1939), BOTSCHANTZEV & VVEDENSKY (1955), SCHERMATOV (1974), and CZEREPANOV (1995). Because only the lectotype, which is in flower, was examined, it is not possible to determine at present the status of A. polyodon.Published as part of AL-Shehbaz, Ihsan A. & Barriera, Gabrielle, 2019, Typification of Edmond Boissier's Cruciferae (Brassicaceae) names enumerated in Flora Orientalis, pp. 1-193 in Boissiera 72 on page 99, DOI: 10.5281/zenodo.763043
