leaf blades elliptic-lanceolate, base short-spurred;

offsets not formed.

erect, simple, 6–15 cm;

leaf blades elliptic or oblanceolate-oblong, 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).
