1.2–12 cm, central strand weak or absent.

1–6 cm, sometimes denuded of leaves at base, central strand absent.

erect or curved, rarely (falcate-) secund when dry, ovate-lanceolate, sharply keeled distally, (1.3–)1.7–2.5(–3.2) mm, 1-stratose or rarely 2-stratose in striae distally;

margins usually recurved throughout or to just before the apex, usually denticulate distally, 1 or 2-stratose;

apices acute or sub-obtuse;

costa percurrent or excurrent as a smooth or weakly denticulate, occasionally decurrent awn, abaxial surface often papillose;

basal marginal cells usually quadrate;

distal laminal cells mostly short-rectangular, 8–10 µm wide, smooth, sinuose.

usually curved to falcate, sometimes falcate-secund or erect when dry, linear-lanceolate to ovate-lanceolate, concave proximally, weakly keeled or concave distally, 1.4–4(–6) mm, 1-stratose with a few 2-stratose striae or patches distally;

margins plane or somewhat erect, rarely weakly recurved, smooth, 2-stratose;

apices rounded or acute, usually ending in a fleshy, multistratose apiculus;
