basal;

petiole 0.5–1 cm;

blade oblanceolate to elliptic, 0.3–1 × 0.2–0.3 cm, thinly pubescent.

rather dense with secondary branches suppressed, greenish to reddish;

bracts 2, similar to proximal leaf blades only reduced, short-petiolate, becoming narrowly elliptic to linear-lanceolate and aciculate at distal nodes, acerose, 0.5–5 cm × 2–7 mm, awns 0.5–1.2 mm.

bracts 2, petiolate or sessile, similar to proximal leaf blades, oblanceolate or narrowly elliptic to linear-lanceolate, 0.3–1 cm × 1–3 mm, awns absent.

1, greenish, cylindric, often ventricose basally, 1–3 mm, without scarious margins or if so then white to pink, thin, and restricted to basal portions of teeth, corrugate, villous abaxially;

teeth spreading, equal, 0.5–2 mm;

awns uncinate or straight with longer ones 2–3 mm and anterior one mostly 2.5–3 mm, these alternating with shorter 1–1.5(–1.7) mm ones.

teeth 5–6, unequal, 3 longer ones 1.5–3 mm, these alternating with 2 or 3 shorter ones 1–2 mm, anterior tooth not leaflike;

awns of prominent teeth uncinate and 1.5–3 mm, those of shorter teeth straight and 1–2 mm.
