--><span class="statement" id="st-undefined" data-properties=""><b>Shrubs,</b> to 0.5–1 m, very strongly rhizomatous. <b>Stems</b>: bark ± smooth, not shredding; twigs scattered, multicellular eglandular-hairy (hairs unbranched) and/or stipitate-glandular-hairy, otherwise glabrous or, sometimes, sparsely unicellular-hairy. <b>Leaves</b> deciduous; petiole multicellular eglandular- and/or stipitate-glandular-hairy, sometimes also unicellular-hairy; blade ovate to obovate, 2–5.5(–6.5) × 0.8–2(–3) cm, thin, membranous to chartaceous, margins entire, plane, ciliate, eglandular-hairy, apex acute to obtuse, often mucronate, abaxial surface glabrous or, rarely, sparsely scattered eglandular-hairy, sometimes sparsely (rarely densely) unicellular-hairy, adaxial surface (lustrous to dull), glabrous or sparsely scattered stipitate-glandular-hairy, sometimes also sparsely unicellular-hairy. <b>Floral</b> bud scales glabrous or densely unicellular-hairy abaxially, margins usually unicellular-ciliate. <b>Inflorescences</b> 4–13-flowered; bracts similar to bud scales. <b>Pedicels</b> 4–15(–20) mm, eglandular- and/or stipitate-glandular-hairy, otherwise glabrous or sparsely (rarely moderately) unicellular-hairy. <b>Flowers</b> opening before or with leaves, erect to horizontal, usually very fragrant and/or nearly mephitic-scented; calyx lobes 0.7–5.5(–10) mm, marginal and scattered stipitate-glandular- or, less commonly, eglandular-hairy, sometimes also unicellular-hairy; corolla white, usually flushed pink or rose (especially on tube), without blotch on upper lobe, funnelform, 23–58 mm, scattered, usually conspicuous, multicellular stipitate-glandular-hairy (hairs forming prominent band along middle of each lobe), otherwise glabrous or, sometimes, sparsely unicellular-hairy on outer surface, petals connate, lobes 8–24 mm, tube rather gradually expanded into lobes, 16–35 mm (equaling or longer than lobes); stamens 5, much exserted, ± unequal, 32–63 mm. <b>Capsules</b> borne on erect pedicels, 10–24 × 4–8 mm, usually densely stipitate-glandular-hairy, otherwise glabrous or densely unicellular-hairy. <b>Seeds</b> without distinct tails, flattened portion of testa well developed at each end; testa expanded, dorsiventrally flattened, ± loose. <b>2n</b> = 26.</span><!--

|discussion=<p>Varieties and forms have been described within <i>Rhododendron atlanticum</i> (see E. H. Wilson and A. J. Rehder 1921; K. A. Kron 1993). Hybrids between it and <i>R. canescens</i> and <i>R. periclymenoides</i> are known. <i>Rhododendron atlanticum</i> is easily confused with the sympatric <i>R. viscosum</i>, which generally is taller, less rhizomatous, hairier, larger-leaved, and later-flowering (i.e., flowers appear after the leaves have expanded).</p>
