Chusquea and Swallenochloa (Poaceae: Bambusoideae): Generic relationships and new species

  • Thomas R. Soderstrom
  • Cleofé E. Calderón


One new species of Chusquea and three of Swallenochloa are described. Morphological characters, especially of the culm leaves and branching, are pointed out as useful in distinguishing the two genera. A key to the 7 recognized species of Swallenochloa is given, and a discussion of its habitat, the páramo. Comment is made upon the recent evolution of the páramo habitat and therefore of the bamboo adapted to it, and reasons offered for the apparent active speciation which characterizes this bamboo genus.
