The lower receptacle is 3 mm long and densely scaly while the upper receptacle 5 mm long is narrowly tubular and somewhat expanding at the apex. The petals are obovate to suborbicular and greenish white. The pseudocarp is suborbicular, measures 2.5-3 cm x 2-2.5 cm, with 4 thin flexible wings which are up to 1.5 cm broad .
