Gynoecium bicarpellate, syncarpous, hypogynous and shortly stalked, supported by a narrow elongated bract. Gynoecium flattened dorsi-ventrally with a rounded base. Carpels united for most of their length. Styles two, short and stout, bent outwards in anthetic flowers. Stigma double-crested, not distinctly papillate and covered by secretion. Pollen grains adhering to stigma tricolpate and striate.
Carpels united up to about 4/5 of their length. Gynoecium wall glabrous. Stigmatic regions along ca 2/3 of the length of styles. Tricolpate striate pollen adhering to stigmatic surface similar to in situ pollen of Lusistemon striatus.
Referring to the flat shape of the gynoecium.
