Bracts linear-spatulate (except for the lowest which is elliptic-oblong), c. 10 by 1-2 mm, attenuate at the base into a 2-3 mm long petiole, obtuse or emarginate at apex, membranaceous, glabrous. Pedicels slender, 2-3 mm, glabrous. Flowers 8-10 mm long, glabrous. Calyx-tube narrowly ellpsoid, 4-5 by 1-2 mm.
