Piloselloides: Answers to key questions in Flora of North America leading to this species.  The answers are in the order you would normally work through the key. The points I have considered most important and evident in the photographs are in bold.

	Leaf blades obovate or oblanceolate to spatulate or lanceolate, lengths (2–) 3–8+ times widths; heads usually (2–) 5–30+ in corymbiform to paniculiform or ± umbelliform arrays, rarely borne singly; NOT [Leaf blades elliptic to ± oblanceolate, lengths 2–4 (–6+) times widths; heads usually borne singly]
	Corollas yellow (often each with abaxial red stripe); NOT [Corollas orange (drying scarlet to purple)]
	Heads (2–) 10–30+, usually in corymbiform to paniculiform, sometimes ± umbelliform, arrays (rarely borne singly in H. triste); NOT  [Heads (1–) 2–5+, in ± umbelliform arrays]
	Leaves usually glabrous, sometimes piloso-hirsute (on midribs and at margins) or scabrellous and/or stipitate-glandular (not both piloso-hirsute and stellate-pubescent); corollas 5–9 mm; NOT [Leaves usually piloso-hirsute and stellate-pubescent; corollas 8–12+ mm]
	Leaves glabrous or piloso-hirsute (on midribs and at margins); involucres 5–6 (–7) mm; florets (40–) 60–80+; pappi 3–4 mm; NOT [Leaves glabrous or scabrellous and/or stipitate-glandular; involucres (6–) 7–10 mm; florets 20–60+; pappi 4–5 mm]
