GENUS INDEX

GENUS CODE: PARTH2
GENUS SCIENTIFIC: Parthenium
GENUS AUTHORITY: L.
GENUS COMMON: Feverfew
GENUS SUMMARY: A genus of about 16 species, herbs and shrubs, of North America and the West Indies. Mears (1975) does not seem to me to be a fully satisfactory explanation of the variation within the genus. Morphologically and ecologically, P. auriculatum seems worthy of specific status, and I have not followed Mearss reduction of it to varietal status. P. integrifolium var. henryanum, var. mabryanum, and var. integrifolium serve to describe real patterns of variation, but are disturbingly confluent morphologically, ecologically, and geographically.

WEAKLEY FLORA

SCIENTIFIC NAME: Parthenium auriculatum
COMMON NAME: Glade Wild Quinine
SYNONYMY: [= C, G, K1, K2, SE, Va; = P. integrifolium var. auriculatum (Britton) Cornelius ex Cronquist - RAB, Z; = P. hispidum Rafinesque var. auriculatum (Britton) Rollins - F, WV; < P. integrifolium - FNA, S; < P. hispidum Rafinesque - W]
PHENOLOGY: Mid May-Aug.
HABITAT: In shallow, xeric, circumneutral soil of glades, barrens, and woodlands, over calcareous rocks (such as dolostone) or mafic rocks (such as diabase).
COMMENTS: Ne. WV south to c. NC and n. AL, west to c. TN. As indicated by the confusion over its taxonomy, the relationships and appropriate taxonomic treatment of this taxon are unclear. It is clearly a close relative of the Ozarkian P. hispidum Rafinesque, and perhaps not readily distinguished from it; some, at least, of our material has creeping rhizomes and heads over 7 mm in diameter, supposed to be distinguishing features of P. hispidum.
