The genus Duchesnea includes two species originally from India: D. indica and D. chrysantha.In Northwestern Argentina the monitoring of wild strawberry-like species was carried out; during 2002-2016, many populations of D. indica and none of D. chrysantha were discovered. Red- and white-fruitedplants of D. indica were collected from disturbed areas and ex situ conserved in green-house and innursery conditions. Were also consulted materials from different national and international herbaria, andwe only found reports of D. indica with red fruit for Argentina. In the present work, we report for the firsttime the presence of D. indica f. albocaput in Argentina and South America, cohabiting with populations ofD. indica f. indica in the underwoods of Tucumán. This finding broadens the distribution range of D. indicaf. albocaput, cited as endemic to Japan by Naruhashi 1992. The morphological and anatomical charactersof the two botanical forms of D. indica (red fruit genotypes and white fruit genotypes) are also presented:fruit color, number of leaflets, and crystal form.
