(erect);

blade narrowly lanceolate to linear or (outer) oblanceolate, (1–)2–6(–9) cm, margins usually entire, rarely shallowly dentate, (inner involute, outer usually flat, base usually with some simple trichomes).

(outer ones spreading, inner erect or ascending);

blade ovate, often broadly so, 4–7 cm, margins repand to lyrate-lobed.

blade narrowly oblanceolate to linear, (1–)2–4(–8) cm, margins flat or involute.

similar to basal, blade oblanceolate or narrowly oblong, reduced in size, (base gibbous).

compact, (elongated and loose in fruit, densely-flowered).

loose, (elongated).

sepals oblong to broadly elliptic, 4–7(–8) mm, (lateral pair subsaccate, median pair cucullate);
