摘　　要：对绵竹(Bambusa intermedia Hsueh et Yi)花器官的形态结构进行解剖观察,其花序属于无限花序,每个假小穗基部都生有潜伏芽。小花类型为开放型,基本结构包括内、外稃各1枚,浆片3枚,雄蕊6枚,雌蕊1枚,柱头羽毛状三分叉。小花中各结构的发育顺序为外稃→内稃→浆片→雄蕊→雌蕊。小穗中小花的发育顺序是由基部向顶部。子房1室,胚珠倒生,侧膜胎座,双珠被。药壁具4层细胞,有大量的败育情况出现。The morphological characteristics of the floral organs of Bambusa interm^dia Hsueh et Yi were observed. Its inflorescence belonged to the indefinite inflorescence, and each of pseudospikelets had dormant buds. The floret type was of open type, and its fundamental structure included lemma （ 1 ）, lodicule （ 3 ）, stamens（6） and pistil （1） with plumate stigma and three branches. The developmental sequence of these structures in florets was lemma→palea→lodicules→ stamens→pistil. The developmental sequence of florets in spikelet was from base to top. Its ovary was unilocular, with parietal placentation, and dual-integument enclosing the anatropous ovule. The anther walls contained 4 cell layers and a lot of aborti onsoccured.
