Utricle morphology of the species in Carex sect. Paniceae (Cyperaceae) and its systematic significance(薹草属少花薹草组（莎草科）的果囊形态及其系统学意义)
用扫描电镜观察了少花薹草组Carex sect. Paniceae（莎草科）26种3变种的果囊形态和微形态特征。结果表明：（1）果囊形状（喙除外）为倒卵球形、椭球形或卵球形，均为钝三棱状，果囊长度为1.99~7.27 mm，喙多弯曲（仅1种C. striatula果囊的喙直立），喙急缩或渐缩，喙长与果囊长度的比值为1/8~1/2，表皮细胞多明显隆起，极少数隆起不明显，且多数性状种内保持稳定；（2）喙口形态分斜截、平截、微二齿和二齿4类，且在种内有变异，如C. arakiana、线柄薹草C. filipes、丝柄薹草C. rouyana、C. purpurifera；（3）可根据果囊长度和喙的收...
