Type specimen: Fromrpa, Volusia County, Orange City, Oct. 12, 
1913 (Ivar T. Tidestrom, no. 7051, in Herb. Tidestrom. Co-types in 
Herbb. Riks Mus., Gray, U. S. Nat. Mus., and Moore). 
The branches of the inflorescence in S. aspericaulis are stouter and 
longer than in either S. Chapmanii or S. odora, as well as being more 
characteristically aggregated in subfasciculate manner. From these 
two species it differs also in the greater roughness of the stems (the 
larger grayish, instead of more frequently brownish or yellowish hairs 
in correspondence to their size, appearing more noticeably transverse 
banded under a lens of moderate power), and in the typical and strong 
goldenrod odor, instead of the anise scent usual in the two species 
named.' The involucral scales in S. odora are distinctly keeled, in S. 
Chapmanii less noticeably, and in S. aspericaulis and the other species 
not at all. From 5. odora, in addition to the above characters, S. 
aspericaulis differs in the oblong, obtuse or at least not acuminate, 
instead of longer, lanceolate leaves, and the wholly glabrous, instead 
of ciliate involucral scales. From S. Chapmanii, whose leaves are 
similar in shape but slightly less oblong or elliptic, the new species 
further differs in not having the blunt prolonged midrib, and in its 
glabrous, instead of minutely pubescent and ciliate involucral scales. 
From S. tortifolia it is distinguished by its leaves all being essentially 
1 In some specimens the anise scent is wanting, but the odor does not seem to change 
its quality.
