glabrous; cicatrices shallowly obtriangular, widely obtrullate, narrowly transversely rhombic, or narrowly transversely elliptic,
2–5 mm tall, 3–6.5 mm wide.

||Racemes 4–10, each 15–60-flowered, glabrous; peduncle 10–25 cm long; sterile bracts lanceolate, oblanceolate, narrowly oblong,
narrowly elliptic, or linear, 15–170 × 3–20 mm, the margin crenulate or entire (rarely denticulate), the apex acute or acuminate; rachis 10–34 cm long; floral bracts lanceolate,
elliptic, narrowly elliptic, oblong, narrowly oblong, or linear, 12–50 × 2–6.5 mm, the margin crenulate or entire, the apex acuminate, acute, obtuse, or rounded; pedicels 16–36 mm
long; bracteoles ovate, oblong, narrowly oblong, or elliptic, 0.7–4 mm long. Hypanthium campanulate, hemispheric, obovoid, or oblate,
4–9 mm long, 4–8.5 mm diam., 1/14–1/9(–1/6) as long as the corolla; calyx lobes triangular, narrowly triangular, linear-triangular, oblong,
narrowly oblong, or ovate, erect or ascending, 3–10(–17) × 1–3 mm, 3/5 as long as the hypanthium to 3/5 again as long, the margin entire or rarely denticulate, the apex obtuse, acute, or acuminate. Corolla subbilabiate, various shades of pink, 43–73 mm long; tube gently to strongly curved, 21–37mm long,(3–)4.5–6.5 mm tall at middle, 2–5 mm tall at mouth, 3.8–7.7 times longer than height at middle; dorsal lobes 26–37 × 1–2.5 mm, equaling
the tube to half again as long, the apex acuminate, the ventral lip elliptic, narrowly oblong, or obovate, 22–32 × 4–7 mm. Staminal column strongly exserted, emerging well
above the lobes; filament tube 36–59 mm long, 3.2–5.6 times longer than dorsal anthers, sparsely pubescent toward apex (rarely glabrous); anther tube (2.5–)3–3.8 mm diam., pubescent at base or over the basal half; dorsal
anthers 10–14 mm long; ventral anthers 7–12 mm long, with tufts of white trichomes 1–2.2 mm long at apex.
||Capsule globose or oblate, 7–12 mm long, 6–15 mm wide, 5–10 mm thick, the pores numerous and scattered over the entire lateral surface.
||Seeds 0.8–1.4 × 0.5–0.7 mm.
