Flora of North America species comparison

prostrate or ascending (very rarely suberect), much-branched (usually from base), (0.1–)0.2–0.6(–1) m. Leaves: petiole ± 1/2 as long as blade;

blade obovate, elliptic, or spatulate, 1–2(–4) × 0.5–1(–1.5) cm, base cuneate and tapering, margins usually entire, plane, rarely slightly undulate, apex obtuse, rounded, mucronulate.

prostrate to ascending, branched mainly from base, 0.1–0.4(–0.5) m. Leaves: petiole shorter than blade;
