 ensis. Medical Botany of U. S.. c^e.) — The original a perennial herb, most 

 related to Solidago ; as now extended a large genus (X. American, mainly west- 

 ern, with an anomalous Andean representative), mostly of suffrutescent or more 

 shrubbv plants, the genuine species with few-flowered heads of marked habit and 

 character, while others are onlv artificially and not definitely distinguislied from 

 Aplopappiis. especially from § Ericomeria. by the total want of ray-flowers. Tet- 

 some genuine Aplopappi are rayless. — DC. 3Iem. Comp. t. 5, cV- Prodr. v. 329
