--><span class="statement" id="st-undefined" data-properties="">Perennials; (stoloniferous, with vegetative rosettes, loosely cespitose to somewhat pulvinate); sparsely to moderately pubescent, trichomes stalked, cruciform, stellate, mixed with simple and forked-stalked ones. <b>Stems</b> usually simple from base, erect to ascending, often branched proximally, (0.6–)1–2(–2.5) dm. <b>Basal</b> leaves: petiole 0–1 cm; blade spatulate, oblanceolate, oblong, or obovate, (0.4–)1–4(–5) cm × (3–)6–15(–20) mm, margins dentate to denticulate, apex obtuse or acute, surfaces usually pubescent, rarely subglabrate, trichomes stellate with simple rays. <b>Cauline</b> leaves 3–5(–6); blade oblong or ovate, 1–3 cm × 5–15 mm, base subcordate or auriculate, margins usually dentate, rarely subentire, apex acute or obtuse. <b>Racemes</b> simple, (lax). <b>Fruiting</b> pedicels ascending to divaricate, 4–10(–12) mm. <b>Flowers</b>: sepals oblong, 2.5–4(–4.7) × 1–2 mm, lateral pair conspicuously saccate basally; petals white, spatulate to obovate, 5–8(–9) × 2–3.5 mm, apex obtuse; filaments 3–5 mm; anthers oblong, 0.7–1.2 mm. <b>Fruits</b> ascending to spreading, torulose, 1.7–3.5(–4) cm × 1–1.7 mm; valves each with midvein absent or obscure, along proximal 1/2; ovules 34–50 per ovary; style 0.3–0.6 mm. <b>Seeds</b> narrowly winged throughout, ovate, 1–1.4 × 0.9–1.1 mm; wing 0.1–0.2 mm wide. <b>2n</b> = 16.</span><!--

|discussion=<p><i>Arabis alpina</i>, the generic type, is variable. It is cultivated extensively for its attractive flowers, and it sometimes escapes from cultivation. There is disagreement as to whether one or more species should be recognized in this complex. European, some African, and most North American plants are recognized as <i>A. alpina</i>; most of the larger-flowered, southwestern Asian plants, which are most commonly cultivated, are recognized as <i>A. caucasica</i> or as <i>A. alpina</i> subsp. caucasica (Willdenow) Briquet. In my opinion, the morphological differences between the two (see key, couplet 3) support recognition of two species, as did R. C. Rollins (1993) and G. A. Mulligan (1996).</p>
