Flora of North America species comparison

root-stocks, ascending, much-branched, bearing rosettes.

decumbent, lateral branches from proximal axils, rosettes formed in proximal axils (giving rise to flowering shoots).

erect or decumbent, simple or branched, 4–30(–40) cm;

leaf blades oblanceolate, spatulate, obovate, or suborbiculate, base not spurred;

offsets not formed.

ascending, appearing angled when dry, simple or branched, 4.7–6 cm;

leaf blades elliptic-oblong or oblanceolate, base not spurred;

offsets axillary rosettes only basally.

alternate, erect to spreading, sessile;

blade green, glaucous or not, not pruinose, oblanceolate, spatulate, or obovate, subterete or somewhat flattened, 10–50 × (4.5–)6–33 mm, base not spurred, not scarious, apex truncate to rounded or obtuse, emarginate or barely notched.

alternate, (loosely imbricate), divergent, sessile;

blade green, not glaucous, obovate or elliptic, rarely lanceolate, subterete, 4.7–7.5 × 2.5–3.4 mm, base not spurred, not scarious, apex obtuse, (surfaces finely papillose marginally).

elongate, paniculate cymes, 12–80-flowered, monochasially 3+-branched;

branches not recurved, 2-forked;

bracts similar to leaves, smaller.

cymes, 3–15-flowered, 2–3-branched;

branches not or only slightly recurved, not forked;

bracts (2–3), similar to leaves, smaller.
