In young greenish floral bud (i.e., Stage I), development of thestamen was obviously earlier than that of pistil (Fig. 3A). The num-ber of stamen varied, from normally two to rarely one or three(Fig. 3B–D). However, each stamen contained a tetrasporangiateanther, which was typical for dicotyledonous species (Xue et al.,1999). In addition, fusion variation could happen between twoclosely neighboring anther chambers with three stamens (Fig. 3E).Each pistil had two stigmas, with the upper one-third solid partand the lower two-thirds hollow part (Fig. 3F). These facts evi-denced that the jasmine style was intermediate between the hollowand solid types. Its normal ovary was biventricular with twoshort funiculus hemianatropous ovules, adhering to the placenta(Fig. 3G–H).
