brosum, vulpinum, muricatum." Chamaeraphis is thus defined in R. Br. 

 Prod. 193 (1810): "Gluma biflora, bivalvis, valvula exteriore minima. Flos- 

 culi bivalves; exterior masculus, valvula exteriore textura interioris glumae; 

 interior minor, chartaceus, femineus. Squamulae 2, hypogynae. Stamina 3. 

 Styli 3! Stigmata plumosa. Semen perianthio cartilagineo inclusum. Gra- 

 men perenne; folia disticha, linearia, stricta, ligula rotundata. Spica unica 

 (Hordei); floribus imbricatis, distichis; rachi flexuosae, parallelis; pedicellis 

 brevibus, juxta apicem intus arista longissima instructis (unde nomen). 

 Obs. — Affinitate proxima panicis, praesertim ultimae sectionis, a quibus vix 

 differt nisi numen stylorum. 1. C. hordeacea. (T.) V. v." R. Brown's 

 genus Orthopogon (1. c. 194) includes O. compositus (P. compositum L.), 

 aemulus, flaccidus, imbecillis, and is Oplismenus Beau v. Pennisetum R. 

 Br., Prod. 195, includes P. compressum, glaucum (Panicum glaucum L.), 

 italicum (Panicum italicum L.), and is the same as Setaria Beauv., but 

 not the same as Pennisetum Rich, in Pers. Syn. 1: 72 (1805). It is my 

 opinion that as genera go in grasses both Setaria Beauv. and Chamaeraphis 

 R. Br. are good genera and should not be united. Schlechtendahl (Linnaea, 

 31 : 420, not vol. 35 as says Kuntze) says of loxophorus, after a discussion of its 

 merits, ". . . . So bilde ich aus diesen Pflanzen eine eigene Abtheilung, 

 welche man Gattung oder Panicum-section nach Belieben nennen mag, und 

 bezeichne Sie mit einem eigenen Namen: Ixophorus." It is founded on 

 Urochloa uniseta. Presl, Rel. Haenk. 1: 319, a plant which Bentham says has 

 not been identified. So this name cannot be safely taken up. 



S. glauca (L.) R. & S. Syst. II, 490 (1817). Beauvois includes this in his 

 genus Setaria as Panicum glaucum. Agi'ost. 51 (1812). Panicum glaucum L. 

 Spec. 56 (1753). In Indiis. Common in cultivated ground. 



S. viridis (L.) Beauv. Agrost. 51, and Atlas, pi. 13: fig. 3 (1812). In the 

 description Beauvois merely includes this in his list of species as Panicum 

 viride. In the index, "Panicum viride Lin. Vid. Setaria, lb. [51]," and 

 under Setaria, S. viridis. In the description of the plate this appears Setaria 

 viridis. It seems proper to give Beauvois as the author of the above combina- 

 tion. P. glaucum (b) L. Spec. ((See above.) P. viride L. Syst. Ed. 10 (1759). 

 Common in cultivated ground.
