reduced, the whole inflorescence thus appearing leafy: pedi- 
cels strongly puberulent: bracts of involucre more sparsely 
somewhat pubescent: proper tube of corolla shorter than 
the campanulate-funnelform limb: styles notably exserted 
and their tips slender: achenes rather short, black, strongly 
angled, glabrous. 
Sapulpa, Indian Territory, 1 Oct., 1895, B. F. Bush, n. 
1440 of my set; labelled E. ageratoides, but of different 
aspect altogether, being much more branching, leafy and 
floriferous, with firmer foliage and that of different cut. 
E. NEMORALE. Stems 2 to 3 feet high, pubescent below, 
the flowering branches and peduncles tomentulose: leaves 
rather thin, deltoid-ovate, truncate at base and short-petio- 
late, the largest 23 inches long by 1$ inches broad near the 
base, coarsely crenate-serrate, the indentations about 10 to 
each margin, both faees very sparsely short-hairy: inflor- 
escence an ample and almost naked cymose panicle: bracts 
of involucre somewhat biserial and slightly unequal, spatu- 
late-oblong, obtuse hirtellous and ciliate: corollas with slen- 
der tube and campanulate limb about equal, the tips of the 
lobes sparsely villous: style branches almost filiform and 
little exserted. 
Along the borders of woods about Knoxville, Tenn., Aug., 
1898, A. Ruth, n. 719, distributed as E. verbenæfolium, and 
this by my own too hasty determination. I was misled by 
the broad and obtuse involucral bracts, and some other 
points at which it diverges from E. aromaticum to which it 
is nearly related, rather than to E. verbenzfolium. 
E. Tracyi. Rigidly erect, often stoutish, 2 to 4 feet high, 
amply corymbose-panicled sometimes from below the middle 
of the stem, this terete, scabro-puberulent, often minutely
