Abstract

Summary12 species of Stenostephanus Nees occur in Bolivia, two of which, S. madidiensis J.R.I.Wood and S. sehuencasii J.R.I.Wood are described as new. Ten species are endemic to the country with all growing on the humid eastern slopes of the Andes. The distribution of all Bolivian species is described and mapped and implications for conservation are discussed. A key to the species found in Bolivia and a table of their principal distinguishing characteristics are provided. The new species are illustrated with line drawings and photographs.
