• Discussion

  Professor Hackel differentiates P. trachyphylla from P. trivialis chiefly on the development of branching stolons and the greater number of nodes of the culm. The type of P. trachyphylla Hack, has not been examined since it is not in the Hackel Herbarium. The specimens cited from La Quinhua grew near the water of mountain brooks and the decumbent sterile shoots extended into the water. Except for these stolons, the plants agree with Poa trivialis. Since the name given by Hackel is untenable, the plants are referred to Poa trivialis until more material is at hand.
