blades narrowly white-margined;

basal oblanceolate, 4–23 × 0.3–1.2(–2) cm, basal leaves generally longer than lowest internode;

cauline leaves opposite, proximal blades oblanceolate to oblong, distal linear-oblong.

blades not white-margined;

basal spatulate or oblanceolate to elliptic-obovate, 7–50 × 1–15 cm, apex rounded to acute;

cauline leaves whorled, blade oblong-lanceolate.

narrow, 1.5–4(–5) cm wide, interrupted proximally, ± continuous distally.
