The peduncle is purple in colour and is finely white pubescent. The sterile bract on the peduncle is acute, 2-3 cm long and green. The fertile bracts are conduplicate, ovate-lanceolate, acute, 2-2.5 x 1 cm in size and green with a purple base.

The pedicel and ovary are 5.5-6.5 x 0.2-0.3 cm in size, purple in colour and finely white pubescent. Dorsal sepal is elliptic, obtuse, 2.1-2.2 x 1.2-1.3 cm in size and finely pubescent on both surfaces. The lateral margins of the dorsal sepal are reflexed. The synsepal is similar in shape and is shorter than the lip, 2-2.2 x 1.6-2 cm. It is bi-keeled on the reverse side and the margins reflexed. The petals are elliptic to obovate, rounded with a size of 2.4 x 1.6 cm. Its margins are reflexed and it is finely white pubescent on the inner surface.

The stigma is 4.5-5 mm long, spatulate and is hidden by the staminode.
