Rafinesque also characterizes this genus and gives Ammi 
capillaceum, Michx., as the type. This is Déscopleura capilla- 
cea, DC. 
SPERMOLEPIS, Raf. Neogen. 2 (1825), not Brong. & Gris. 
Leptocaulis, DC. Mem. Omb. (1829). 
This genus is based on Daucus divaricatus, Walt., which is 
Sison pusillum, Michx., Leptocaulis divaricatus, DC., and Apitum 
divaricatum, Wood. If this species and its allies are to be kept 
distinct from Apzum, 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. 101 (1819), not 
Humb. and Bonpl. 
Musenium, Nutt. in T. and G. Fl. N. A., i. 642 (1840). 
Perceiving that the generic name Marathrum was already 
used, Rafinesque substituted for it Adorivm, eleven years before 
Nuttall named Musenium. The names of Rafinesque and Nuttall 
are both based on Seseli divaricatum, Pursh. 
Solidago juncea, Ait. var. RAMOSA, 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 ends. 
In fields, western New Jersey and eastern Pennsylvania 
(Porter), Ohio (Sullivant), and West Virginia (Millspaugh). 
Strikingly different in appearance from S. juncea. Professor 
Porter informs me that he sent specimens of the plant to Dr. 
Gray, after the volume of the Synoptical Flora containing the 
Composite was issued, and was told that he had not seen it before. 
Cyperus Houghtont, Torr. Ann. Lyc. N. Y. iii. 277 (1836). 
This species was described by Dr. Torrey from a specimen 
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. Schweinitzi?, as is 
indicated in pencil in his copy of the Monograph of North 
American Cyperacez, and in his copy of Steudel’s Cyperacez. 
In his herbarium the types of both species are mounted on the
