标本馆的发展规划：1、通过采集和交换（特别是收集我国没有分布的重要类群）等途径，增加标本馆藏量；2、建立稳定的经典分类研究队伍，培养后备人才，深入开展植物分类学研究；3、加快标本馆数据库的建设；4、进一步加强植物学科普教育基地建设。

Pollen morphology and exine ultrastructure Pollen exine ultrastructure of five species in Stachyurus and one species of its sister group, Crossosoma californicum, were investigated under transmission electron microcopy for the first time. The pollen morphology of Crossosoma californicum was studied under Scanning Electron Microcopy.

花粉形态学和外壁超微结构在透射电镜下研究了旌节花属5个代表种和1个外类群的花粉外壁超微结构，并在扫描电镜下研究了外类群Crossosomataceae 1个代表种的花粉形态学特征，结合前人的研究，探讨了上述性状的分类学意义。

The problem of taxonomy of every species were carried out research combining with the histological structure, morphology of pollens and the characteristic of embryology; while the relation betweeen Cycadaceae and Stangeriaceae and Zamiaceae were analysed.
