Sisymbrium griffithianum Boiss., Diagn. Pl. Orient. ser. 2, 1: 23. 1854.

Type: “Hab. in regno Cabulico circâ Quettah (Griffith Nº 1481)”.

Holotypus: PAKISTAN: “Quettah“, s.d., Griff ith 1481 (G-BOIS [G00330374]; iso-: K [K000618633, K000618634]) .

= Olimarabidopsis pumila (Stephan) Al-Shehbaz et al. in Novon 9: 303. 1999.

Notes. – Because of its descending or strongly reflexed (vs ascending or strongly incurved) fruits, there has been some debate as to whether or not S. griffithianum should be recognized as a distinct species in Olimarabidopsis Al-Shehbaz, O’Kane & R.A. Price or be merged with O. pumila .

The isotype duplicate at K [K000618633] has two plants one with ascending and the other with reflexed fruits, whereas the other K isotype [K000618634] has only ascending, strongly incurved fruit. By contrast, the G-BOIS holotype is a single plant with sharply reflexed fruit.

Furthermore, another material (Griffith 1483, K) has eight plants, of which four have divaricate-ascending fruit and the other four have sharply reflexed fruits.Therefore, the recognition of Sisymbrium griffithianum as distinct from Olimarabidopsis pumila is unjustified. For related matters and conservation of the epithet “ pumilum ”, see GERMAN & AL-SHEHBAZ (2015).
