green, narrowly lanceolate to linear-lanceolate, linear, or narrowly elliptic, 2–8 cm, not fleshy, margins plane, sometimes ± wavy, flat or involute, 0(–5)-lobed, apex acuminate;

lobes widely spreading, linear to narrowly lanceolate, apex acute.

green to sometimes purple, narrowly oblong or lanceolate to sometimes linear or narrowly ovate, (0.8–)1–5(–6.5) cm, not fleshy, margins wavy, flat or involute, 0–5-lobed, apex rounded or obtuse, rarely acute;
