except on the underside of the leaves (and there not always), 
and is remarkable for the deep green colour of the upper 
side of the foliage, and the pale and glaucous hue beneath ; 
and is that which we have here represented. Our speci- 
men, now figured, is from the Glasgow Botanic Garden. 
Native specimens I possess from the late Mr. Scuwetnirz 
of Bethlehem, Dr. Dartineton of West Chester, and Dr. 
Suort of Kentucky. It flowers about autumn. 
Descr. Perennial. Stems erect, four feet or more high, 
branched above, generally deeply tinged with dark purple, 
more or less scabrous. Leaves opposite, the uppermost one 
alone excepted, mostly on very short footstalks, ovato- 
lanceolate, slightly tapering at the base, acuminated at the 
extremity, glabrous, scabrous and dark green above, below 
smooth, pale, glaucous, glabrous, or clothed more or less 
copiously with soft down, three-nerved, the margin rather 
distantly and not deeply serrated, the upper ones almost 
quite entire. The upper and alternate leaves are small, 
and may be considered bracteas. Involucre of many lance- 
olato-subulate, spreading or squarrose scales. Receptacle 
slightly convex, chaffy: scales or palee tricuspidate. Flo- 
rets of the ray bright yellow: their abortive germens with 
two unequal, chafty, subulate, opposite scales : those of the 
disk with generally two, sometimes more broadly subulate, 
soft, deciduous ones
