AL-Shehbaz, Ihsan A. & Barriera, Gabrielle, 2019, Typification of Edmond Boissier’s Cruciferae (Brassicaceae) names enumerated in Flora Orientalis, Boissiera 72, pp. 1-193 : 73

Hesperis secundiflora Boiss. & Spruner in Boiss., Diagn. Pl. Orient. 1: 70. 1843.

 Hesperis laciniata subsp. secundiflora (Boiss. & Spruner) Breistr. in Mém Soc. Bot. France 33: 84. 1952.

Type: “Hab. in faucibus montis Hymetti propè Athenas inter frutices”.

Lectotypus (designated here): GREECE: “Hymettus”, IV.1842, Boissier s.n. ( G-BOIS [ G00332229 ]; isolecto-: BM [ BM000750011 ], G [ G00446096 , G00446097 ], GOET [ GOET002618 ], HBG [ HBG506202 ], JE [ JE00002544 ], K [ K000693651 ], KW [ KW000127976 , KW000127977 ], LD [ LD1011478 ], PH [ PH00014464 ], W [ W00075688 , W18890310416 ]) . Syntypus: GREECE: “Hymetti fauces”, V.1842, Spruner s.n. ( G [ G00446094 , G00446095 ], G-BOIS [ G00332227 ], GOET [ GOET002617 ], K [ K000693652 ]) ( Fig. 12 , p. 56) .

Notes. – As indicated by MERMOUD (1980), it is not possible to pin down the exact dates of Boissier’s 1842 trip to Greece, as he collected in Athens then Hymette before moving further in the fieldwork.

The problem of this species arises from placing all material of G-BOIS in two folders, the lectotype of which includes six plants in flower without a collection date ( Fig. 12 , p. 56), but all distributed duplicates, which have printed yellow labels, indicated a collection date in April 1842, and these are recognized as isolectotypes. The second folder in G-BOIS, the syntype, has three plants with developing fruit a collection date of May 1842.

Although BOISSIER (1843) did not give collectors names in his original description of the species, we agree with TAN & SUDA (2002), who did not lectotypify H. secundiflora , in considering Boissier’s and Spruner’s collections as syntypes.
