P. waltheri Lam. Encycl. Suppl. 4: 282 (1816). "Panicum foliis ovali- 

 lanceolatis, amplexicaulibus, glaberis; ,vaginis subtomentosis, basi circa 

 nodum, colloque barbatis; panicula sessili glabella, subramosa; glumis pubes- 

 centibus, valvula extima ovali. (N.) Panicum latifolium Michx. Flor. Bor. 

 Amer. 1: pag. 49, ut non Linn. C'est a tort que Waltherius & Michaux ont 

 pris cette plante pour le panicum latifolium, No. 86. Quoique tres-rapprochee, 

 elle en differe evidemment par ses feuilles plus courtes, amplexicaules & non 

 retrecies en petiole a leur base; par les gaines pubescentes, presque tomen- 

 teuses. barbues sur les noeuds a leur base & a leur orifice. La panicule est 

 sessile, presque glabre, mediocrement rameuse, renfermee entre les feuilles 

 superieures; les values calicinales tres-legerement pubescentes; I'exterieure 

 ovale. Cette plante croit dans la Virginie & a la Caroline, dans les bois & 

 les pres. Perennial. (V. s. in herb. Mich.)" Swartz makes the following note 

 in his Obs. Bot. 36 (1791): "Panicum latifolium. S. V. 107, 27. S. pi. 160, 26. 

 Obs. Synonym Sloanei non hujus,sed P.glutinosi. Prodr. p. 24." The following 

 is the description given by Linnaeus, of P. latifolium L. Spec. 58 (1753): "Pani- 

 cum panicula racemis lateralibus simplicibus, foliis ovato-lanceolatis collo 

 pilosis. Gramen virginianum, lato brevique folio, panicula rariore. Moris, 

 hist. 3, p. 196, f. 8; t. 5, f. 4. Gramen miliaceum sylvaticum maximum, sem- 

 ine albo. Sloan, jam. 34; hist. 1, p. 114, t. 71, f. 3. Habitat in America. Folia 

 latitudine Commelinae, ad fauces amplexicaulia; extus collo circum fauces 

 villoso, etiam basi foliorum margin piloso. Panicula valde mediocris ex 

 racemis lateralibus, non subdivisis, sed pedicellos proprios, nee subdivisos 

 proferentes. Flores mutici majusculi." Wyandotte, Cherokee. 



SETARIA Beauv. Agrost. 113 (1812), not Ach. (1798). According to the 

 rules of priority this name cannot be used for our foxtails, because it was 

 used earlier for a group of lichens. For reasons given below it does not 

 seem best to follow the check-list and use Chamaeraphis R. Br., as recom- 

 mended by O. Kuntze. Hence I have retained Setaria, leaving it to a mono- 

 grapher to apply a new name. The original description of Setaria is said 

 to occur in Palisot de Beauvois' work, Flor d'Oware et de Benin en Afrique, 

 1807, a work which I have not seen. (Bentham, Notes on Gramineae, 47.) 

 Bentham .states that the genus was there founded upon Setaria longiseta, 

 which is not a Setaria as now recognized, but Pennisetum unisetum. Setaria, 

 Beauv. Agrost. 51. "Panici spec, Lin. Juss., etc.; Orthopogonis spec. R. 

 Brow." Following the description comes the list of species to be included in 

 this genus: "Spec. Panicum erubescens, geniculatum, germanicum, glaucum, 

 italicum, purpureum, sericeum, setosum, verticillatum, villosum, viride, um-
