During the preparation of the treatment of the family Heliotropiaceae for Argentina, several names were identified as needing typification to stabilize their nomenclature. As a result, lectotypes are designated for six names (Heliophytum anchusifolium (Poir.) DC. var. angustifolium DC., Heliotropium claussenii A. DC. f. robustior Chodat, H. inundatum Sw. f. elliptica Chodat & Hassl., H. margaritense Hassl. ex I. M. Johnst., H. salicoides Cham., and Tournefortia elegans Cham.) and second-step lectotypes for two names (Heliotropium andinum Rusby and H. maximum Chodat & Hassl.). Furthermore, remarks on types of three names (Heliotropium chrysanthum Phil., H. rugosum Phil., and T. paniculata Cham.) are provided.
