1. Aconitum swatense Tamura in Acta Phytotax. Geobot. 19:108, f.45.1963.

Sepals pale purple, glabrous. Pedicel up to 4.5 cm long.

Type: Described from Swat.

The photograph and description suggests it might be a variable form of Aconitum chasmanthum.

2. Aconitum swatense vars. kashmeriense and bracteatum Qureshi & Chaudhri in Pak. Syst. 3(1):5.1978.

The figure and description of var. kashmeriense suggest Aconitum violaceum and those of var. bracteatum, suggest Aconitum chasmanthum. Gatherings that may be attributed to Aconitum swatense var. kashmeriense but are typical Aconitum violaceum are: R.R. & I.D. Stewart 3467 from Sonamarg & Kashmir and R.R. Stewart et al. 1120 from Lowari Pass, Chitral.
