摘要： 本文对国产獐牙菜属和花锚属药用植物的花瓣进行了扫描电镜的研究。发现实验样品花瓣的表面纹饰(包括初级雕纹与次级雕纹)具各种类型,在属间、种间以及种与变种间都存在稳定区别,具有一定的分类意义。研究结果为近缘植物分类提供了新的证据和建议。文中并附检索表与扫描电镜照片。
关键词: 獐牙菜属, 花锚属, 花瓣, 表面纹饰
Abstract: This paper reports the SEM(Scanning Electron Microscope) studies on the petals of medicinal species of Swertia and Halcma in China, viz., Swertia bimaculata Hook. f. et. Thoms, ex C. B. Clarke; S. angustifolia Buck-Ham. ex D. Don; S. tenuis T. N. Ho et S. W. Liu; S. macrosperma (C. B. Clarke) C. B. Clarke; S. punicea var. lutesccns Franch. T. N. Ho; S. cincta Burk and Halenia corniculata (L.) Cornaz.It is found that the surface features including the primary and secondary ornamentations, e. g. the reticulate, lophate and excrescence ones and the curvatura of the outmost periclinal epidermis cell walls etc., differ from one another with some taxonomic significance at genus, species and variety level. The results may provide new proof and suggestion to the original classification. The characters of the species are described in detail with SEM photographs and a diagnostic key is also presented briefly.
