Cynoglossum glochidiatum was published in 1836, whereas C. wallichii in 1837; therefore, the name ‘C. wallichii var. glochidiatum’, although published validly, was incorrect when published. Here two separate species are recognized Since the combination C. glochidiatum var. wallichii hasn't been made, those under C. wallichii var. glochidiatum as C. glochidiatum Wallich ex Bentham in J. F. Royle, Ill. Bot. Himal Mts.: 306. 1836, and those under C. wallichii var. wallichii as C. wallichii G. Don, Gen. Hist. 4: 354. 1837.
