 slightly woody plant, much branched and \evy leafy at least to the mid- 

 dle; root fibrous as if annual; stem terete, covered with a thin arach- 

 noid flocculent wool; branches ascending, flexuous, ending in 1-3 dense 

 rounded pedunculate corymbs; leaves opposite, petiolate, lanceolate, 

 gradually narrowed to an obtusish tip, cuneate at the base, l-1.5(-3) 

 cm. long, 2-4(-10) mm. wide, with about 7 crenations on each side,

Obviously close to the preceding, yet readily distinguishable both 

 by its very different leaf -contour and by its pubescence of exceedingly 

 fine white wool, the individual hairs l)eing obscure and implexed, not 

 clearly spreading as in E. microphyUum.

 ous or distinctly shrubby, 8-15 dm. high; stems forking above;

 or rather abruptly rounded to an obtusish apex, cuneate to a short- 

 petioled base, crenately many-toothed on each side, 3-6 cm. long, 

 4-10 mm. wide, pinnately many-veined from a strong midrib, grayish- 

 puberulent above, white-woolly beneath; corymbs terminal on long 

 erect almost leafless opposite or alternate branches; heads crowded, 

 about 6 mm. high and 4 mm. in diameter, about 27-flowered; involu- 

 cre campanulate, about 3-seriate, cottony at the base; scales lance- 

 oblong, acuminate, green or toward the tip often dark-purple, at 

 length somewhat tawny-stramineous; cHsk alveolate, at maturity 

 more or less elevated; corollas lilac, blue, or white (Rusby & Pennell), 

 the proper tube about equalling the gradually enlarged throat; achenes 

 1.8 mm. long, dark, glabrous except for traces of hispidity near the 

 summit.— Suppl. 355 (1781); J. E. Sm. Ic. iii. t. 09 (1791); HBK.
