© 2015, The Author(s). 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. 18 species are described as new of which 14 are endemic to Bolivia: Ipomoea appendiculata J. R. I. Wood & Scotland, I. chiquitensis J. R. I. Wood & Scotland, I. exserta J. R. I. Wood & Scotland, I. juliagutierreziae J. R. I. Wood & Scotland, I. gypsophila J. R. I. Wood & Scotland, I. huayllae J. R. I. Wood & Scotland, I. lactifera J. R. I. Wood & Scotland, I. longibarbis J. R. I. Wood & Scotland, I. mendozae J. R. I. Wood & Scotland, I. mucronifolia J. R. I. Wood & Scotland, I. odontophylla J. R. I. Wood & Scotland, I. paradae J. R. I. Wood & Scotland, I. psammophila J. R. I. Wood & Scotland and I. spinulifera J. R. I. Wood & Scotland. The remaining four are also found in Brazil: I. cerradoensis J. R. I. Wood & Scotland, I. cryptica J. R. I. Wood & Scotland, I. graniticola J. R. I. Wood & Scotland and I. mucronatoproducta J. R. I. Wood & Scotland. Of particular interest is I. lactifera which is a crop wild relative of the sweet potato. The name I. paludicola J. R. I. Wood & Scotland is provided for the plant usually treated as a form of I. asarifolia (Desr.) Roem. & Schult. but originally described by Meisner under the illegitimate name I. serpens Meisn. The new combination I. hewittacea (Kuntze) J. R. I. Wood & Scotland is made and is the correct name for the plant currently known as I. piresii O’Donell. The hitherto accepted names I. echioides Choisy, I. pedata G. Don, I. peredoi O’Donell, I. philipsonii O’Donell, I. piurensis O’Donell, I. santacrucensis O’Donell, I. sawyeri D. F. Austin and I. tapirapoanensis Hoehne are treated as synonyms of, respectively, I. paulistana (Silva Manso) Stellfeld, I. mauritiana Jacq., I. reticulata O’Donell, I. batatoides Choisy, I. acanthocarpa (Choisy) Aschers. & Schweinf., I. oranensis O’Donell, I. neurocephala Hallier f., and I. caloneura Meisn. I. subtomentosa (Chodat & Hassl.) O’Donell is treated as a var. subtomentosa (Chodat & Hassl.) J. R. I. Wood & Scotland of I. maurandioides Meisn. and a new variety erecta J. R. I. Wood & Scotland is described for I. bonariensis Hook. The following taxa are lectotypified: I. serpens Meisn., I. rubens Choisy, I. procurrens Meisn, I. chiliantha Hallier f., I. pinifolia Meisn., I. incarnata (Vahl) Choisy, I. hirsutissima var. boliviana Meisn., I. virgata Meisn., I. chondrosepala Hallier f., I. argentea Meisn., I. bonariensis Hook., I. pedata G. Don, I. magnifolia Rusby, I. purpurea var. diversifolia (Lindl.) O’Donell, Convolvulus paulistanus Silva Manso, C. cymosus Ruiz & Pavon and C. indivisus Vell., the last three being basionyms of I. paulistana, I. ramosissima Choisy and I. indivisa (Vell.) Hallier f. respectively. A neotype is provided for I. megapotamica Choisy to ensure current usage is maintained. Species of Turbina Raf. occurring in Bolivia are treated as belonging to Ipomoea based on ongoing molecular studies resulting in the new combination I. amazonica (D. F. Austin & Staples) J. R. I. Wood & Scotland and a new name I. sericosepala J. R. I. Wood & Scotland for Turbina cordata (Choisy) D. F. Austin & Staples.
