Flower stems 1 or 2, erect, 11 - 22 (- 35) cm long, including the panicle, 2.5 mm thick in the base, pinkish green, bracts 1.5 - 3.5 x 0.8 - 1.3 cm, obovate, margins pinkish, panicle 4 - 11 flowers, usually two branched, (1-) 3 - 5 (-6) flowers per branch, pedicels straight, 8 - 16 mm long., bracteoles lanceolate, 0.5 - 1.3 0.2 x 0.5 cm, green.

* The authors decided to place this new species in series Gibbiflorae. In view of the small size of this plant, the short stem and especially the urceolate corolla this classification is rather doubtful.
