XII. Stellerianae. Stout perennials, with creeping woody rootstocks or decumbent bases, 
densely white-tomentose. Leaves obovate in outline, pinnately divided into elliptic obtuse 
divisions, Heads comparatively few and large. Involucre 5-6 mm. high, subhemispheric, as 
high as broad, 40—-50-flowered. Corollas glandular-granuliferous, those of the ray-flowers 
subcylindric, 2-toothed, those of the disk-flowers trumpet-shaped, 5-toothed. Styles in both 
short-exserted, two-cleft; branches in the former linear-oblong, obtuse, in the latter reflexed, 
truncate and erose at the apex.

XIII. Discolores. Rather low perennial herbs, with branched rootstocks, or stems some- 
what suffruticose at the base. Leaves pinnately dissected, with linear more or less spreading 
divisions, usually again cleft or toothed, often somewhat revolute on the margins, green above, 
more or less tomentose beneath. Heads not very numerous, nodding; inflorescence racemi- 
form or with racemiform branches. Involucre hemispheric, sparingly arachnoid. Corollas 
glandular-granuliferous, those of the ray-flowers cylindric or subcylindric, tapering upwards, 
2-toothed, those of the disk-flowers trumpet-shaped, 5-toothed. Style of the former exserted, 
with linear-filiform branches, that of the latter mostly included, with short recurved branches, 
truncate and erose at the apex.

A perennial, with a horizontal rootstock; stems 5—7 dm. high, striate, slightly floccose 
‘when young, glabrate in age; leaves 4-7 cm. long, sessile, ovate in outline, loosely floccose 
when young, but soon glabrous above, white-tomentose beneath, thin, not revolute-margined, 
pinnatifid, with linear or linear-lanceolate acute divisions; divisions of the larger leaves again 
cleft or toothed; heads numerous in a leafy panicle with racemiform branches, nodding; in- 
volucre hemispheric, 3.5—-4 mm. high and as broad; bracts 10-12, in three series, more or less 
arachnoid-tomentose, yellowish, the outer linear-lanceolate, nearly as long as the innermost;
