Three New Species and Two New Records of Greigia Regel (Bromeliaceae) from Bolivia

摘要

We describe three new endemic species of Greigia Regel (Bromeliaceae) from Bolivia: Greigia acebeyi B. Will, T. Kromer, M. Kessler, D. Karger and H. Luther, Greigia marioae B. Will, T. Kromer, M. Kessler, D. Karger and H. Luther, Greigia membranáceaB. Will, T. Kromer, M. Kessler, D. Karger and H. Luther. Greigia danielii L.B.Smith and G. stenolepis L.B.Smith vel aff. are reported for the first time for Bolivia. A key to the eight Bolivian species of Greigia is provided. The genus Greigia Regel comprises large, mostly terrestrial bromeliads occurring in disturbed vegetation along roadsides and trails as well as in the understory of upper montane forests from Mexico to the tropical Andes as well as in temperate rain forests of central and southern Chile (Will and Zizka 1999, Kromer 2000, Kromer et al. 2006). Greigia was first reported for Bolivia by Luther (1998a, 1998b) who described the three new species G. atrocastanea, G. cochabambae, and G. kessleri based on a limited number of herbarium collections. Subsequent collections, especially by T. Kromer and A. Acebey, have expanded the number of specimens available from Bolivia. These have been studied by B. Will in the scope of a revision of the genus.
