Inflorescence a densely-flowered spike, ovate to slightly oblong, 8.3-15.4 x 3.8-6.7 cm; flowers tubular with two lateral bracteoles, subtended by a single bract on the abaxial side; floral bract 1.9-3.4 x 0.7-1.4 cm, oblong and keeled adaxially, acute to slightly obtuse, upper margins slightly scarious and entire, proximally pubescent, becoming pubescent to pilose on the distal abaxial surface and densely pubescent on the distal adaxial surface; bracteoles 2.7-3.9 x 0.2-0.5 cm, lanceolate to broadly linear, acute to acuminate, the upper half pilose. Flowers sessile to subsessile; calyx 3.8-5.1 cm, four of five sepals fused to 1/4-1/2 their length, the abaxial sepal free or connected to other sepals near calyx base, sepal lobes lanceolate to broadly linear, acute, pilose; corolla light pink, 5.6-6.2 x 1.0-1.4 cm, tubular or slightly curved, slightly inflated above constricted tube 1.1-1.8 x 0.5-0.9 cm, densely pilose with two minute lapel-like lateral lobes and a small denticle at the base of the corolla mouth, lateral lobes slightly to fully reflexed, denticle 1.7-3.3 mm, corolla mouth 1.4-2.0 cm; stamens 4, inserted in the corolla at the point of constriction, 3.4-4.2 cm, one pair slightly shorter than the other, filaments straight with slightly inflated bases, pubescent to tomentose zone at base of stamens and ringing interior surface of corolla at level of insertion, anthers 3.0-5.0 x 2.0-3.0 mm, calceiform, one-celled, small knob or spur on proximal end from vestigial theca, apical pore elongated and slightly recurved, even with corolla mouth to slightly exserted at maturity; pistil recurved ca 90° below stigma, stigma exserted, clavate to nearly capitate, slightly bilobed dorsiventrally.
