170 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 



Panicum berteronianum Steud. Syn. PI. Glum. 1: 50. 1854. Based on Setaria berte- 

 roniana Schult. 



Panicum psilocaulurn Steud. Syn. PI. Glum. 1: 50. 1854. "P. glaucum var. Trin. 

 Ic. t. 196 A. P. imberbe Poir sec. Trin. Setaria gracilis H.B. * * * Am. austr." It 

 is probable that the description is based on the Brazilian specimen which was the 

 plant from which Trinius's plate is drawn. Trinius says that figure A is Setaria 

 gracilis Kunth. The name is changed, doubtless, because of the earlier Panicum 

 gracile R. Br. 



Setaria glauca var. laevigata Chapm. Fl. South. U. S. 578. 1860. Based on Panicum 

 laevigatum Ell. 



Setaria glauca B imberbis Griseb. Fl. Brit. W. Ind. 554. 1864. Based on Panicum 

 imberbe Poir. 



Setaria glauca y penicillata Griseb. Fl. Brit. W. Ind. 554. 1864. Based on Panicum 

 penicillatum "W., Tr.," which is P. penicillatum Willd.

 Panicum purpurascens H. B. K. 



Panicum imberbe y latifolium Doell in Mart. Fl. Bras. 2 2 : 157. 1877. Several speci-

 Panicum dasyurum Nees. 



Setaria streptobotrys Fourn. Mex. PI. 2: 47. 1886. Several specimens are cited, the 

 first being Galeotti 5832 from Real del Monte. This specimen has not been examined, 

 but two of the others have been seen (Bourgeau 231, Liebmann 345). 



Chamaeraphis glauca var. penicillata" Gris. (W.); " Kuntze, Rev. Gen. PI. 2: 767. 1891. 

 Based on Panicum pencillatum Willd. 



Chamaeraphis glauca var. imberbis "Trin. (Poir.);" Kuntze, Rev. Gen. PI. 2: 767. 

 1891. Based on Panicum imberbe Poir. 



Setaria perennis Hall; Smyth, Check List PI. Kans. 26. 1892; Trans. Kans. Acad. 

 13: 102. 1893. " Frequent in damp alkaline and saline bottoms in central and south- 

 western Kansas." The relation of Hall to this species is not clear. The name does 

 not appear in E. Hall's Plantae Texanae 41873). The type specimen, now in the 

 National Herbarium, was collected at Hutchinson, Kansas, by B. B. Smyth in 1890. 



Setaria gracilis 8 purpurascens Arech. Anal. Mus. Nac. Montevideo 1: 164. 1894. 

 Based on Panicum purpurascens H. B. K. 



Setaria gracilis y latifolia Arech. Anal. Mus. Nac. Montevideo 1: 165. 1894. Based 

 on Panicum imberbe y latifolium Doell, inasmuch as Panicum virescens and P. glaucescens 

 Salzm. are given as synonyms (see notes on these names). 



Setaria gracilis e dasyura Arech. Anal. Mus. Nac. Montevideo 1: 165. 1894. Based 

 on Panicum dasyurum Nees. 



Chamaeraphis ventenatii Beal, Grasses N. Amer. 2: 153. 1896. Based on Setaria 

 ventenatii Kunth. 



Chamaeraphis glauca var. laevigata Beal, Grasses N. Amer. 2: 155. 1896. Based on 

 Panicum laevigatum Muhl. 



Chamaeraphis glauca var. perennis Beal, Grasses N. Amer. 2: 156. 1896. "Florida, 

 Curtiss 3614*." Curtiss is given in parenthesis as author of the varietal name. Curtiss 

 3614* bears a printed label with the name " Setaria glauca Beauv. var. perennis." No 

 date is given. There is nothing to connect this with S. perennis Hall. 



Chamaeraphis glauca var. geniculata Beal, Grasses N. Amer. 2: 156. 1896. Based 

 on Panicum geniculatum Lam.
