This variety Has hitherto passed as S. aureus, var. Ba/samitae, 
of authors, but it is asomewhat stouter plant with longer petiolate 
lower leaves, and with more pronounced stem-leaves than in 
typical specimens of the species proper. It is somewhat inter- 
mediate between the northern S. Za/samitae, Muhl, and the 
southern S. Sma//i?, Britton. 
* * Introduced species: heads inconspicuously radiate, or rayless. 
+ Pubescence viscid-glandular.

pinnatifid with rounded sinuses and angulate-sinuate lobes: head 
radiate ; rays minute: achenes glabrous. — Sp. ii. 868, & ed. 2, 1217:
