arising at slightly different heights, not forming just 1 rosette, bluish green, quinate, quinate-ternate, or rarely 1–2-pinnate;

petiole sheathing basally;

blade ovate-deltate, 2.5–5.5 × 3–6(–8) cm, surfaces glabrous, channeled when fresh, margins curved upward from near midrib (sometimes visible only proximally in dried material);

leaflets not overlapping, primary leaflets undivided or little divided, penultimate segments narrow, usually less than 2 mm wide; ultimate segments (5–)7–24, fewer on nonflowering plants, linear, (4–)15–35(–45) × 1–3 mm, relatively narrow, channeled, margins entire, apex acuminate, terminal segment 9–30(–45) mm;
