Parlatoria griffithiana Boiss., Diagn. Pl. Orient. ser. 2, 1: 23. 1854.

Type: “Hab. in regno Cabulico (cl. Griffith No 1472)”.

Holotypus: AFGHANISTAN: sine loco, s.d., Griffith 1472 (G-BOIS [G00330375]; iso-: K [K000693285, K00693286, K00693287]) .

= Arabis bijuga G. Watt in J. Linn. Soc., Bot. 18: 378. 1881.

Notes. – BOISSIER (1854) based the species description solely on the unicate in his herbarium and therefore that unicate is the holotype.

He indicated in Flora Orientalis that Parlatoria griffithiana ought to be removed from the genus and placed in Sisymbrium sect. Arabidopsis, a position that influenced SCHULZ (1924) in recognizing the plant as Arabidopsis mollissima var. griffithiana (Boiss.) O.E. Schulz, and later tentatively accepted by HEDGE (1968). The holotype was correctly annotated by Hedge in March 1965 as “ Arabis sp. ?”, whereas Schulz annotated it on 19 Sept 1920 as “An genus novum?”.

In every aspect of the plant, Parlatoria griffithiana is indistinguishable from Arabis bijuga, and although Boissier’s epithet predates Watt’s, it cannot be used because JAFRI (1956) described A. griffithiana Jafri based on a different type.
