I also got hold of the publication, where it is mentioned (Ipomoea (Convolvulaceae) in Bolivia <https://link.springer.com/article/10.1007/s12225-015-9592-7> (Abstract- An account of the genus *Ipomoea* L. in Bolivia is presented. 102 species are recognised in the country and each of these is described. Notes are provided on diagnostic features, distribution, habitat, phenology and conservation status. A dichotomous key to all species is provided together with additional informal keys focussing on outstanding features of morphology and ecology. Line drawings illustrate the new species described and photographs are provided to facilitate identification and draw attention to key diagnostic features. Maps of the distribution in Bolivia of selected species are also provided. ….)) as below: 26. *Ipomoea acanthocarpa *(Choisy) Aschers. & Schweinf.
