Recent research has suggested that this poorly known species and Ligusticum pilgerianum H. Wolff (Repert. Spec. Nov Regni Veg. 27: 307. 1930, not Fedde ex H. Wolff, loc. cit. 322. 1930) are conspecific with Notopterygium incisum. Certainly the petal shape is unusual in Ligusticum, but further work is needed to confirm these findings; if upheld the name N. weberbaurianum should be applied to the taxon. Ligusticum pilgerianum H. Wolff was described from Sichuan, and is allied to L. acuminatum according to the original description, but we have not seen the type (H. Smith 3544).
