摘要
本文报道了飘拂草属15种、2变种的果皮微形态特征。通过立体显微镜和扫描电子显微镜对果实的形态、果皮的纹饰进行观察及比较研究。结果表明:飘拂草属在果皮微形态特征上存在着较为明显的种间差异,可为种的区分提供依据,同时也为系统发育与演化提供有价值的资料。
The present paper reports the microstructural features of nutlet surfaces to Fimbristylis Vahl. A total of 15 species, 2 varieties all collected from Fujian Province, were examined under light microscope-and scanning electron microscope. The result has exhibited a complex and high morphological and micromorphological diversity. The microstructural features have some significance for the delimitation of species.
