Rafinesque also characterizes this genus and gives Ainmi 

 capillacenm, Michx., as the type. This is Discopleura capilla- 

 cea, DC. 



Spermolepis, Raf. Neogen. 2 (1825), not Brong. & Gris. 



Lcptocaitlis, DC. Mem. Omb. (1829). 

 This genus is based on Dauais divaricatus, Walt., which is 

 Sison pusillum, Michx., Leptocaiilis divaricatus, DC, and Apiiim 

 divaricatum, Wood. If this species and its allies are to be kept 

 distinct from Apium, L. as has been done by Coulter and Rose, 

 it should be under Rafinesque's generic name. 

 Adorium, Raf Neogen. 3 (1825). 



Marathrum, Raf Journ. Phys. Ixxxix. loi (18 19), not 

 Humb. and Bonpl. 



Museimim, Nutt. in T. and G. Fl. N. A., i. 642 (1840). 



Perceiving that the generic name MaratJiriLin was already 

 used, Rafinesque substituted for it Adorium, eleven years before 

 Nuttall named Musenium. The names of Rafinesque and Nuttall 

 are both based on Seseli divaricatum, Pursh. 



Solidago juncea. Ait. var. RAMOS A, Porter and Britton, n. var. 



Differs from the typical plant in the numerous, strict, erect 

 branches, the racemes numerous, slender, erect or slightly re- 

 curved at the en'ds. 



In fields, western New Jersey and eastern Pennsylvania 

 (Porter), Ohio (Sullivant), and West Virginia (Millspaugh). 

 Strikingly different in appearance from 5. juncea. Professor 

 Porter informs me that he sent specimens of the plant to Dr. 

 Gray, after the volume of the Synoptical Flora containing the 

 Compositae was issued, and was told that he had not seen it before. 



Cyperus Hoiightoni, Torn Ann. Lye. N. Y. iii. 277 (1836). 



This species was described by Dr. Torrey from a si^ecimen 

 collected by Dr. D. Houghton at the Lake of the Isles, North- 

 west Territory, in August, 1831, (No. 73), and the type of it is 

 preserved in the Columbia College Herbarium. He subsequently 

 concluded that it was not distinct from his C. ScJiweinitzii, as is 

 indicated in pencil in his copy of the Monograph of North 

 American Cyperaceae, and in his copy of Steudel's Cyperaceae. 

 In his herbarium the types of both species are mounted on the
