Flora of North America species comparison

rootstocks, decumbent and ascending, branched, (sometimes papillose), bearing terminal rosettes and above ground shoots.

decumbent, branched basally, (fleshy), with numerous decumbent branchlets, not forming rosettes.

erect, simple or branched, 3–18 cm;

leaf blades elliptic-lanceolate, base short-spurred;

offsets not formed.

(axillary), erect, simple or branched, 5–10 cm;

leaf blades ovate, base not spurred;

offsets not formed.

(not easily detached), alternate, spreading-erect to erect or ascending, sessile;

blade dull gray-green or bluish green, green, or reddish green, often glaucous, lanceolate, elliptic-lanceolate, or elliptic-ovate, subterete, 4.2–13 × 1.5–3.5 mm, base very short-spurred, base of withered blade at times becoming scarious, apex obtuse or obtusely apiculate, (surfaces papillose).

(persistent), alternate, spreading, sessile;

blade yellow-green, not glaucous, ovate, subterete, somewhat flattened, 5–8 × 3–4 mm, (thick, turgid), base not spurred, not scarious, apex apiculate, (surfaces minutely papillose, caused by reflections of inner facets of windowed cells).

cymes, 5–25-flowered, (1–)3(–6)-branched;

branches ascending, spreading to erect, or recurved, forked;

bracts similar to leaves.

cymes, 6–12-flowered, simple or 2-branched, sometimes with short branch at base with solitary flower;

branches not recurved, sometimes forked;

bracts similar to leaves, smaller.

sepals erect, connate basally, pale green to yellow-green, ovate or lanceolate, equal, 2–5 × 1–2 mm, apex acute or, rarely, obtuse, (often papillose);

petals widely spreading from suberect base, distinct, canary to golden yellow, lanceolate, elliptic-lanceolate, or linear-lanceolate, canaliculate, 6–9.2 mm, apex acute to acuminate with minute mucronate appendage;

filaments yellow;

anthers yellow, sometimes suffused with red;
