摘要

吧噹藤(Calomus longisetus Griff)之成熟藤莖經掃描電子顯微鏡觀察顯示：基本組織中之特異細胞含束狀草酸鈣針晶體，薄壁細胞腔中有聚生狀內含物。特異細胞呈圓筒形。直徑為鄰近薄壁細胞之兩倍至數倍，具初生細鮑壁，無壁孔。緊臨基本薄璧細胞之纖維細胞壁上密布簇晶狀矽粒，薄壁細胞上並留有晶痕，且呈倒臥狀圓筒形成串排列。細胞內含物及簇晶狀矽粒之結晶度及化學組成以偏光顯微鏡及X光能量散射分析儀測定之。

The mature stems of Calamus longisetus Griff were studied. Inorganic inclusions were observed by unsing light, polarizing and scanning electron microscopes. Two types of cell inclusions were found in ground tissues, aggregate grains and raphids in the cell cavities of parenchyma cells and idioblasts, respectivcly. Druse-like silica grains were found on the fiber walls next to ground parenchyma cells. Their chemical composition, degree of crystallization and formation were also discussed.
