 There are two sheets of Panicum scopa- 

 riuni in the Herbarium of the Paris 

 Museum, one with the following 

 label: "Pajiicutn scoparium Lam. 

 donne par le C. Michaux, Herb. 

 Mus. Paris, Herbier de Lamarck 

 acquis en novembre, 1886," which is 

 evidently Lamarck's type. (Fig. 

 12. ) The second sheet is identical 

 with this and bears the following 

 label: ^'Panicum scoparium Lam. in 

 pratis sylvestris, Carolina, Herb. 

 Mus. Paris, Herbier de I'Amerique 

 septentrionale d' Andre Michaux." 

 Some American authors have recog- 

 nized that Panicum scoparium of 

 Michaux was identical with P. visci- 

 durn Ell., but wrongly considered 

 Michaux's plant distinct from Panl- 

 rum scoparium Lam. Both La- 

 marck's and Michaux's specimens 

 of J\ scoparinii) are identical with 

 the form long known as Panicum 

 riscidum Ell. For the plant wrongly 

 considered l)y Elliott as I'aulcmn 

 scoparium, we propose the following name: Panicum ravenelii Scribn. & ^lerrill, 

 nom. nov. {Panicum scoparium of Ell. Sk. Bot. S. C. and Ga. 1: 119. 1817. 

 NotLam. Encycl. 4: 744. 1797.) 

 Patiicum pid)esceus Lam. is a late, much-branched form oi Pa)iinn)i scoj)ariiim Lam. 

 In the Herb. Mus. Paris there is one sheet of this species bearing the following 

 label: "Panicum pubescens Lam.,Hab. in pratis sylvestribus Carolinse :i/,no. 7, 

 Herb. Mus. Paris, Herbier de I'Amerique septentrionale d' Andre Michaux." 

 On this sheet are two specimens, one a fragiuoiit much dried and torn, the other 



Fk;. 12. — Panicum f:rojKn-i(iiii Lam; a, ?), spikelets. 

 Drawn from type siiecimeii in the Herbarium of 

 tlie I'aris Museum of Natural History.
