Hesperis scabrida Boiss. in Ann. Sci. Nat., Bot. ser. 2, 17: 64. 1842.

Type: “[Aucher-Eloy] N. 166, Mesopotamia ”.

Holotypus: SINE PATRIA: “ Mesopotamia ”, 1835, Aucher-Eloy 166 (P [P00234982]; iso-: G-BOIS [G00332226]) .

Notes. – BOISSIER (1842a) based his species description solely on the holotype that he annotated and from which he took fragments consisting of a leaf and two fruiting lateral branches.

The exact type locality of H. scabrida remains unknown, as Mesopotamia sensu Boissier includes the areas between the Tigris and Euphrates rivers in Turkey, Syria, and Iraq.

The specimens cited by CULLEN (1965) under this species were shown by DVOŘÁK (1972b) to be H. novakii Dvořák and H. unguicularis . Furthermore, DVOŘÁK (1980: 1041) doubted the occurrence of H. scabrida in Iraq and suggested that the type was probably collected from Syria or Turkey.
