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缩情况区分部分近缘种，如线柄薹草与少囊薹草C. egena、浙江薹草C. zhejiangensis与显舌薹草C. macroglossa；（4）果囊长度、喙长与果囊长度的比值在sect. Paniceae s.s.与sect. Laxiflorae 2组间有显著差异，对两组的界定有一定价值；（5）被视为组或亚属重要分类性状的果囊横切形状（三棱状或双凸状）在界定少囊薹草组与相关组时无意义，果囊形态对界定少花薹草组有重要的系统学意义。

报道了笔者在查阅、整理与鉴定浙江菊科Asteraceae 植物过程中发现的一个分布于浙江的中国新记录种：舌叶天名精Carpesium glossophyllum，以作为中国种子植物区系资料的补充。与浙江产的烟管头草C. cernuum 的区别在于该种植株矮小，分枝少；基生叶宿存；茎生叶披针形至狭披针形，宽0.6~1 cm，近全缘，几无柄；苞叶3~5 枚，条状披针形，长10~12 mm，总苞较小，直径8~12 mm；总苞片先端钝，具齿蚀状锯齿。此外，将先前误定为三脉叶兔儿风Ainsliaea trinervis 的长圆叶兔儿风A. oblonga 组合为A. kawakamii 的变种A. kawakamii var. oblonga。

报道笔者在采集、整理和鉴定时发现的2个中国新记录种和11个省级新记录，以作为中国莎草科Cyperaceae薹草属Carex植物志资料的补充.中国新记录种为斯丁通薹草Carex staintonii和刺猬薹草C. echinata,分别见于西藏吉隆和墨脱；省级分布新记录有湖北新记录截喙薹草Carex truncatirostris、南平薹草C. nanpingensis和纤细薹草C． pergracilis，贵州新记录种丝叶薹草C. capilliformis和糙囊薹草C. scabrisacca，西藏新记录种小粒薹草C. karoi、云南薹草C. yunnanensis、紫鳞薹草C. purpureosquamata和金佛山薹草C. jinfoshanensis, 四川新记录短叶亮绿薹草 C. finitima var. attenuata， 浙江新记录种鹞落薹草 C. otaruensis.

诸葛菜属Orychophragmus Bunge为中国特有植物，至今为止在分类学上仍存在较大分歧.在文献考证、野外采集和标本查阅的基础上，对诸葛菜O. violaceus、铺散诸葛莱O. diffusus(O. violaceus var. homaeophyllus）、湖北诸葛莱O. hupehensis、太白诸葛菜O. taibaiensis的13个形态性状进行了观测.基于对6个居群58个个体的形态性状的观测数据，进行了主成分分析(PCA).结果表明：(1)PCA散点图显示所分析的所有个体可分成3类，即诸葛菜、湖北诸葛菜+太白诸葛菜、铺散诸葛菜；(2)结合以往研究结果，诸葛菜属只含1个种，将湖北诸葛菜和铺散诸葛菜处理为诸葛菜的亚种，并做了 新组合[Orychophragmus violaceus subsp. hupehensis (Pamp.) Z-H Chen et X. F. Jin, subsp. homaeophyllus (Hance) Z-H Chen & X. F. Jin],同时将太白诸葛菜和秭归诸葛菜 O. ziguiensis作为湖北诸葛菜的异名.
