--><span class="statement" id="st-undefined" data-properties=""><b>Annuals,</b> biennials, or short-lived perennials, 20–60(–80) cm; usually fibrous-rooted, sometimes apparently taprooted, slender caudices simple or branched. <b>Stems</b> erect, sparsely to moderately strigose or loosely strigoso-villous or nearly glabrous, often also minutely glandular distally. <b>Leaves</b> basal (persistent) and cauline; blades oblanceolate to spatulate, 20–140 × 3–16 mm, cauline spreading, gradually reduced distally, margins usually entire, rarely serrate-dentate, faces glabrous or sparsely villoso-hirsute, distal sometimes also glandular. <b>Heads</b> 1 or 3–35 in corymbiform to thyrsiform arrays (peduncles curved-ascending). <b>Involucres</b> 5–11 × 8–22 mm. <b>Phyllaries</b> in 2–3(–4) series (often purplish, inner apices attenuate to caudate), glabrous or sometimes sparsely hirsute, minutely glandular. <b>Ray</b> (pistillate) florets in 2 series; outer 150–250, corollas white to pink or purplish, laminae 3–4.5 mm (filiform), erect; inner fewer than outer, corollas tubular, elaminate. <b>Disc</b> corollas 4.2–6.2 mm. <b>Cypselae</b> 2–2.4 mm, 2-nerved, faces sparsely strigose; pappi: outer of setae, inner of (18–)25–35 (accrescent) bristles. <b>2n</b> = 18.</span><!--

|discussion=<p><i>Erigeron</i> angulosus Gaudin, E. asteroides Andrzejowski ex Besser, E. droebachiensis O. F. Mueller ex Retzius, E. elongatus Ledebour, and E. politus Fries, names previously used for the widespread American plants of <i></i></i>var.<i><i> kamtschaticus</i>, refer to Eurasian endemics (summary in G. L. Nesom 2004e). E. Hultén (1968) restricted the name <i></i></i>var.<i><i> kamtschaticus</i> to a single North American collection made at “Junction Firth R. and Mancha Creek on the Alaska-Yukon boundary in August 1961,” treating all others of the species in North America as subsp. politus. Entire-leaved plants apparently are the common form of the species even in the Kamtschatka area, and <i></i></i>var.<i><i> kamtschaticus</i> appears to be correct at varietal rank for the North American plants. <i>Erigeron</i> kamtschaticus has been treated as a species separate from <i>E. acris</i> in other recent literature. Circumscription and rank of <i>E. acris</i> and closely related taxa are in need of study.</p><!--
