AL-Shehbaz, Ihsan A. & Barriera, Gabrielle, 2019, Typification of Edmond Boissier’s Cruciferae (Brassicaceae) names enumerated in Flora Orientalis, Boissiera 72, pp. 1-193 : 97

Alyssum muellerii Boiss. & Buhse in Nouv. Mém. Soc. Imp. Naturalistes Moscou 12: 16. 1860.

Type: “In den Vorbergen des Kisildagh bei Gamarlu in der Nähe von Eriwan, 21 April 1847. [Buhse] No 93/1. Gebirge bei Jesd (Deh ballo), 24 April 1849 (florens). [Buhse] No 1358”.

Lectotypus (designated here): IRAN: “Yesd”, 1847, Buhse 1357 ( G-BOIS [ G00332390 ]; isolecto-: LE [ LE00013023 ], P [ P00868519 ]) . Syntypus: ARMENIA: sine loco, 1847, Buhse 93/1 ( G-BOIS [ G00332391 ]) .

Notes. – The collection number for the lectotype was erroneously given in the original publication.

Although Buhse 1358 was collected in 1849, the lectotype has a printed label showing Persia, Dr. Buhse, and the year 1847, as well as in Boissier’s handwriting of “1357 [for 1538] Alyssum Buhseanum n.sp. Yesd”. Discrepancy in the year of collections is considered here as an error that resulted from using a label pre-printed prior to the collection year.

The lectotype sheet also carries Dudley’s 1961 annotation of “A. mülleri Boiss. et Buhse. Cotype!”. However, neither 1357 nor 1358 were listed in BOISSIER’s (1888) index.

The duplicate at P is treated here as a likely isolectotype because it was collected from “Dehballoh”, though no year or collection number accompany it.
