Nomenclatural Revision of Heliotropiaceae Names Linked to Southern Cone Taxa

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.
