    Purple coneflower (English)
    Stems erect, unbranched or ± branched (glabrous or hairy, hairs appressed, ascending, or spreading, uniseriate).
    petiolate (at least basal and proximal cauline, petioles progressively shorter distally);
    blades (1-nerved, 3-nerved, or 5-nerved) linear to lanceolate or elliptic to ovate (distal smaller), bases mostly attenuate (decurrent on petioles) to cuneate, sometimes rounded or cordate, margins usually entire, sometimes dentate or serrate, faces usually hairy (hairs uniseriate, usually with 1–4 rings of cells surrounding bases), sometimes glabrate or glabrous.
    Heads radiate, borne singly (on relatively long peduncles).
    Involucres crateriform to hemispheric, 12–40 mm diam.
    Phyllaries persistent, 15–50 in 2–4 series (spreading, recurved, or reflexed, linear or lanceolate to ovate, subequal to unequal, mostly herbaceous, apices mostly attenuate, abaxial faces usually hairy, sometimes glabrate or glabrous).
    Receptacles hemispheric to conic, paleate (paleae orange to reddish purple distally, surpassing disc corollas, bases partially surrounding cypselae, bodies keeled, apices abruptly constricted to awnlike tips; discs 10–45 × 15–40 mm).
    Ray-florets 8–21, neuter;
    corollas dark purple to pale-pink, white, or yellow (tubes glabrous or sparsely hairy, laminae spreading, reflexed, or drooping, linear to elliptic or obovate, abaxial faces glabrous or moderately hairy).
    Disc-florets 200–300+, bisexual, fertile;
    corollas pinkish, greenish, reddish purple, or yellow, tubes shorter than throats (often sparsely hairy), lobes 5 (erect or spreading to recurved), triangular (pollen usually yellow, usually white in E. pallida).
    Cypselae (tan or bicolored with dark-brown band distally) 3-angled or 4-angled (faces smooth to finely tuberculate, glabrous or sparsely hairy);
