Identification Key
1. Cypselae with 2-10 ridges, the ridges yellow to red-brown, translucent; phyllaries glabrous or densely pilose, sometimes stipitate-glandular
1. Cypselae without yellow to red-brown, translucent ridges; phyllaries moderately to densely stipitate-glandular
1. (Key A) Phyllaries 1.5-2.5 mm wide, in 2-3 series, stipitate-glandular
1. Phyllaries 0.5-1(1.3) mm wide, in 4-5 series, eglandular or stipitate-glandular
2
2. Phyllary apices spreading to reflexed, flexuous or twisted, usually long-attenuate to acute, eglandular; cypselae with 6-10 ridges
2. Phyllary apices appressed to slightly recurved at the tip, acute to short-acuminate, sometimes stipitate-glandular; cypselae with 2-6 ridges
3
3. Stem erect; leaf margin eciliate
4
3. Stem procumbent, ascending, to erect; leaf margin eciliate or sparsely to densely woolly
5
4. Stems 30-80 cm long, green to dark purple; leaves to 100 (esp. on tall plants), linear to linear-lanceolate or elliptic, sometimes undulate, strongly twisted; heads 4-30(50) in open corymbiform arrays
4. Stems 30-200 cm long, often dark purple; leaves to 200 on tall plants, linear to narrowly linear, flat or slightly undulate or twisted; heads 20-100, in compact subumbelliform to paniculiform arrays
5. Perennials; stems procumbent, branched proximally, with up to 80 flowering branches; mid and distal cauline leaves to 100+, crowded, linear-elliptic to oblong, margins eciliate, glabrous; heads in compact umbelliform arrays; phyllaries appressed, glabrous to glabrate, sometimes outer ones with a few stipitate glands proximally
5. Biennials or short-lived perennials; stems procumbent to erect, simple or branched; mid and distal cauline leaves 10-50+, sometimes crowded, linear, lanceolate, oblong, or ovate, sparsely to densely woolly at least along margins; heads in lax to compact corymbiform or subumbelliform arrays; phyllaries glabrate to densely woolly, sparsely to densely stipitate-glandular
6
6. Biennials or short-lived perennials, 10-100 cm long; stems procumbent to erect, simple or branched; mid to distal cauline leaves broadly lanceolate, oblong, to ovate, margins sparsely to densely woolly or sometimes distal cauline eciliate, faces sparsely to densely woolly, distal sometimes glabrate; heads few in lax corymbiform arrays; phyllaries sparsely to densely pilose or woolly and densely stipitate-glandular, rarely glabrous or glabrate
6. Usually short-lived perennials to 80 cm long; stems ascending to erect, rarely procumbent, usually simple; mid to distal cauline leaves linear, lanceolate, to linear-oblanceolate, margins coarsely long-pilose, faces sparsely pilose to glabrate; heads usually in subumbelliform arrays, sometimes in compound subumbelliform arrays; phyllaries glabrate, apices spreading
1. (Key B) Cauline leaves eglandular, sericeous
1. Cauline leaves stipitate-glandular (glands sometimes hidden by hairs), woolly to sericeous-tomentose
2
2. Phyllary apices spreading to reflexed, attenuate to long-attenuate
3
2. Phyllary apices erect, acuminate, acute, to obtuse
4
3. Stems decumbent, ascending, to erect; heads in corymbiform to paniculiform arrays
3. Stems erect; heads in paniculiform arrays
4. Mid cauline leaf faces woolly or tomentose; involucres yellow-green in bud
5
4. Mid cauline leaf faces usually sparsely hirsute, rarely woolly; involucres green in bud
6
5. Mid cauline leaf blades obovate or oblanceolate, bases cuneate to slightly auriculate-clasping, marginal cilia rarely more than 1 mm, faces appressed-tomentose; distal blade faces appressed-tomentose, sparsely stipitate-glandular
5. Mid cauline leaf blades oblong, oblong-elliptic, sometimes ovate to lanceolate, bases truncate to rounded, some marginal cilia 2-3 mm, faces woolly; distal blade faces glabrate to sparsely woolly-pilose, densely stipitate-glandular
6. Stems ascending to erect, tips usually nodding before heads form; mid leaf faces moderately hirsute, larger glandular hairs 0.3-0.9 mm long; heads in compact to moderately open, corymbiform to paniculiform arrays
6. Stems erect, simple, tips erect to ascending before heads form; mid leaf faces glabrate to sparsely strigillose, larger glandular hairs 0.01-0.3 mm long; heads in compact to lax, corymbiform arrays
