Two kinds of multicellular trichomes, glandular and non-glandular, occur on the abaxial side of the perianth lobes, androphore and ovary wall; sunken multicellular glands are generally present on the adaxial surface of the perianth lobes. The development of these trichomes and glands shows that they are epidermal in origin. The flowers are uni-sexual. The perianth is tetramerous and each perianth lobe is traversed by three bundles. The origin and distribution of the staminal traces recall the condition in fasciculate androecium. The ovary is tetralocular below and unilocular above. The placentae which lie along the septal radii receive the half ventrals of adjacent carpels but do not fuse to form common ventral bundles. Thus the placentation may be described as tending towards the parietal condition. The stigma is commissural.
