Erysimum elbrusense Boiss., Fl.

AL-Shehbaz, Ihsan A. & Barriera, Gabrielle, 2019, Typification of Edmond Boissier’s Cruciferae (Brassicaceae) names enumerated in Flora Orientalis, Boissiera 72, pp. 1-193 : 40-41

Erysimum elbrusense Boiss., Fl. Orient. 1: 202. 1867.

Type: “Hab. in regione alpinâ montis Elburs supra Derbent (Ky exs. 164!)”.

Holotypus: IRAN: “Prope nives. In m. Elbrus pr. Derbend”, 17.V.1843, Kotschy 164 ( G-BOIS [ G00332141 ]; iso-: BM [ BM001254048 ], BP, G [ G00343195 , G00343196 , G00343197 ], GOET [ GOET002587 ], K [ K000075401 , K000075402 ], MO [ MO3831784 ], P [ P02272706 , P02272707 ], TUB, W [ W0022401 ]) .

Notes. – All of the collections above were made on the same day and have the same collection number. However, the W unicate differs from the others and the protologue in the locality data, and that is why it is considered as a questionable isotype.

The label data in the protologue, G-BOIS holotype, and all other isotypes are exactly the same. Derbend is a former village at the outskirts of Tehran, and the distance from Tehran to Mt. Tochal is several kilometers.

POLATSCHEK & RECHINGER (1968: 290) erroneously listed the type locality data as “In regione alpine M. Totschal supra Derbent” based of the unicate at W. The locality data of that sheet is “ad nives deliquescentes montis Totschal prope Tehran ” and it is exactly the same way cited by POLATSCHEK (2010: 257), who designated it as the lectotype.

There is no evidence indicating that Boissier used more than the single specimen in his herbarium to draft the species description and, therefore, the G-BOIS duplicate has to be taken as the holotype.

Erysimum alpestre Kotschy ex Boiss., Fl. Orient. 1: 202. 1867 [nom. illeg.] [non Jordan].

Type: “Hab. in regione alpinâ districtus Kassan Oglu Ciliciae Kurdicae prope Gorumse (Ky Suppl. 92!) in monte Berytdagh Cataoniae ad fodinas ferreas (Haussk!)”.

Lectotypus (first step designated by POLATSCHEK, 2011: 397; second step designated here): TURKEY: “Plantae ex montibus Kassan Oghlu. Crescit in alpinis jugis ad Gorumse”, 7200' [2190 m], 15.V.1859, Kotschy 92 ( G-BOIS [ G00154032 ]; isolecto-: B, BP, P [ P02272688 , P02272689 ], S, W [ W0026611 , W0026612 ]) . Syntypus: TURKEY: “Taurus Cataonicus. Berytdagh”, 8000' [2440 m], 10.VIII.1865, Haussknecht s.n. ( G-BOIS [ G00154033 ]) .

= Erysimum adcumbens (Boiss.) Polatschek in Willdenowia 13: 88. 1983.

Notes. – A second step is needed to correct the Polatscheck’s lectotypification from W to G-BOIS. The lectotype is a collection folder of two sheets, one of which with a label as above and the other with the printed label: “Th. KOTSCHY. Iter Orientale 1859”.

POLATSCHEK (2011) indicated that the lectotype is W0026611 and W0026612 (two duplicates), but there are three sheets all have the same printed label and were annotated by Polatschek in 1985 as holotypes.

 Erysimum adcumbens (Boiss.) Polatschek in Willdenowia 13: 88. 1983.

Type: “Hab. in monte Argaeo Cappadociae alt. 7500' (Ky!)”.

Holotypus: TURKEY: “Plantae Argaei montis Cappadociae. In jugo versus Caesaream”, 7500' [2290 m], 30.V.1859, Kotschy 200 ( G-BOIS [ G00332143 ]; iso-: B [ B100068547 , B100068552 ], BM [ BM001254049 ], BP, E [ E00373161 ], G [ G00446063 ], JE [ JE00002778 ], K [ K000075403 ], P [ P02272690 , P02272691 ], PR, S [ S04-346 ], US [ US00100406 ], W [ W0026769 , W0026770 ]) .

Note. – DAVIS et al. (1988) reduced E. adcumbens to synonymy of E. sintensianum Bornm. , but the former is readily distinguished from the latter by having abaxially pubescent (vs glabrous) petals.

Erysimum aucheri Boiss. in Ann. Sci. Nat ., Bot. ser. 2, 17: 78. March 1842 [nom. illeg.].

 Erysimum pulvinatum J. Gay, Erysim. Nov.: 5. January 1842.

Type: “Habitat in Persiae borealis montibus Elamout (Auch. exsicc. nº 4111! in herb. mus. Par. et Deless.)”.

Holotypus: IRAN: “Elamout”, s.d., Aucher-Eloy 4111 ( P [ P02272758 ]; iso-: BM [ BM000522226 , BM001254044 ], FI [FI010138], G [ G00343199 , G00343186 ], G-BOIS [ G00332144 ], K [ K000693821 , K000693822 ], KW [ KW000127968 ], P [ P02272759 ], S, W [ W0026673 ]) .

= Erysimum caespitosum DC., Syst. Nat. 2: 497. 1821.

Notes. – Erysimum aucheri is illegitimate because the single type collection cited is the same as that of the earlier published E. pulvinatum J. Gay (see the E. persicum entry above).

The duplicate P 02272759 is from Cosson’s herbarium that was not consulted by Gay.

POLATSCHEK (2011: 420) recognized P 02272758 and P 02272759 as the holotype and isotype, respectively, of E. pulvinatum J. Gay which he synonymized with E. caespitosum .
