The pistillate flower of Hodgsonia macrocarpa Cogn. usually grows in solitary in the leafaxil. Its floral parts appear in the following order: sepals, petals, stamens, and pistil. Each of the sepals, petals, or staminodes is not equal in size at first, but later they will approach to equal. In addition, the bases of calyx and corolla unite to form the "floral tube". During the early stage of flower development, the staminate primodia are quite noticeable, but in the mature flower they become rudimentary. The staminate flower of Hodgsonia usually recemose in the leafaxil. Each of the inforescence with 15–20 floral buds or each of the flowers has a bract at the base. The developmental sequence of the staminate flower is similar to the pistillate flower. The carpal primodium of the staminate flower appears as normal, but it will not develop further and stays on rudimentary. The petal marginal meristem of pistillate and staminate flower keeps its activity for a long time, after the lengthening of the petal venation and forms 5–7 thread-like appendages.
