Pseudodraba hystrix (Hook. f. & Thomson) Al-Shehbaz et al. in Pl. Diversity Evol. 129: 73. 2011.

= Malcolmia ciliaris Boiss., Fl. Orient. Suppl.: 44. 1888, syn. nov.

Type: “Hab. in Affghaniâ loco non indicato (Hulton!)”.

Holotypus: AFGHANISTAN: sine loco, s.d., Aitchison s.n. (G-BOIS [G00332185]) .

Notes. – The identity of Malcolmia ciliaris remained a mystery since its publication about 140 years ago. RECHINGER (1968) and ZOHARY et al. (1980) did not mention the species, and AL-SHEHBAZ et al. (2014) indicated that the status of the species is unknown.

An examination of the holotype reveals beyond any doubt that the plant belongs to the monospecific Pseudodraba Al-Shehbaz et al.

The collector was listed in the protologue as Hulton, instead of Aitchison on the unicate in G-BOIS.
