II. Species Whose existence in the Territory Does Not 



Seem to be Confirmed 



1. Panicum capillare L. Although some of the Oregon forms 



seem to approach this species, it seems best to refer them 

 to P. harhipulvinatum Nash. 



2. Panicum pubescens Lam. 



3. Panicum dichotomum L. Both of these seem referable to 



P. occidentale Scribn. 



4. Panicum, scoparium Lam. Evidently P. Scrihnerianum 



Nash. 



5. Aristida fasciculata Torr. Probably A. bromoides HBK., 



and its occurrence very doubtful. 



6. Melica interrupta Trin. The name seems to be incorrectly 



applied. 



7. Panicularia fluitans Kuntze. Probably P. leptosfachya 



(Buckl.) Piper. 



8. Poa glauca Vahl. An introduced species — not confirmed 



by any later collector. 



9. Festuca heterophylla Lam. Probably F. occidentalis Hook. 

 10. Elymus dasystachys Trin. Apparently not correctly applied. 



III. Species whose Taxonomic Limits are now Generally 



Understood Differently 



1. Panicum sanguinale L. = Digitaria sanguinalis (L.) Scop. 



2. Panicum crus-galli L. = Echinochloa crus-gaUi (L.) Beauv. 



3. Phalaris amethystina Trin. = P. calif omica Hook. & Arn. 



4. Sporobohis cuspidatus Wood = vS. Richardsonii (Trin.) 



Merr. 



5. Sporobohis depauperafus Scribn. = Muhlenbergia squarrosa 



Rydb. 



6. Sporobohis Bolanderi Vasey = Poa multnomae Piper. 



7. Sporobohis gracilUmus Vasey = Muhlenbergia filiformis 



Rydb. 



8. Sporobohis simplex Scribn. = Muhlenbergia filiformis Rydb. 



9. Sporobohis filiformis Scribn. = Muhlenbergia filiformis 



Rydb. 



10. Agrostis asperifolia Trin. = A. exaratn Trin.
