In this paper, the biological characteristics of florescence, spikelet and inflorescences structure, morphogenesis formation of inflorescence, megasporogenesis and the development of female gametophytes were studied systematically by using anatomy structure, scanning electron microscopic and paraffin section methods. The results were as followed:(1) Phyllostachys praecox was the bamboo flowering fragmentarily; the cultivation changed the characteristic of flowering; the plantlets of flowering were complex and splitted into three kinds: the plantlet flowering before continued flowering; the plantlet flowering before stopped flowering and the plantlet changed into flowering. The inflorescence of Ph. praecox was indefinite inflorescence or called false inflorescence, and actually it was flower stress structure. Its basal unit was pseudospikelet with two kinds: apical spikelet and lateral spikelet. The floret had one lemma, one pelea, three stamens, one pistil and three lodicules.
