AL-Shehbaz, Ihsan A. & Barriera, Gabrielle, 2019, Typification of Edmond Boissier’s Cruciferae (Brassicaceae) names enumerated in Flora Orientalis, Boissiera 72, pp. 1-193 : 99

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 .
