摘要
目的:本文通过性状鉴别与显微鉴别的方法来对粗毛淫羊藿的外在形态特征以及显微特征进行研究,为其近缘种分类的鉴定提供参考依据。方法:采用眼观结合体视显微镜观察粗毛淫羊藿的植物形态特征,并采用光学显微镜对粗毛淫羊藿叶表皮及花粉粒和药材粉末显微特征进行观察和分析。结果:在植物形态上,花茎复叶回数为一回三出复叶,叶型为披针形、叶质较薄,为革质,在叶缘上有细密的刺齿,叶尖锋利,叶片上表面的颜色为深绿色,没有毛,下表面为灰绿色或灰白色,有密被粗短伏毛,基出脉有7条,凸起显著;花瓣有距;花色为白色、紫色、淡紫色;萼片两轮,外萼片4枚,内萼片4枚;花瓣远较内萼片长,呈角状距,根茎竖走,多叉状分支而弯曲。在粉末显微鉴定观察上,可见花粉粒类似球形或长球形、极面观三裂圆形,极面观小,外壁表面具有清晰的网状纹饰,网脊上密布均匀的瘤状突起,网眼很多,形状大小不一。结论:本研究方法简便环保、准确可靠,可为淫羊藿物种真伪的鉴定提供参考依据。
Objective:In this paper,the external morphological and microscopic characteristics of Epimedium acuminatum were studied by means of trait identification and microscopic identification to provide a reference basis for the identification of the classification of its closely related species.Methods:The plant morphological features of Epimedium acuminatum were observed by eye observation combined with stereomicroscope,and the leaf epidermis and microscopic features of pollen grains and herb powder of Epimedium acuminatum were observed and analyzed by light microscope.Results:In terms of plant morphology,the number of compound leaves of the flowering stem was one ternate compound leaf,the leaf type was lanceolate,the leaf texture was thin and leathery,there were fine prickly teeth on the leaf margin,the tip of the leaf was sharp,the color of the upper surface of the leaf blade was dark green without hairs,and the lower surface of the leaf blade was greyish-green or greyish-white with densely coarsely and shortly amblypygous hairs,the basal veins had 7,which were significantly convex;the petals were spurred;the flower color was white,purple,and lilac;there were two whorls of sepals,with four outer sepals,four inner sepals and one inner sepal.sepals in two whorls,outer sepals 4,inner sepals 4;petals much longer than inner sepals,angular spacing,rootstock vertically walking,multiforked branching and curved.On the observation of powder microscopic identification,it was seen that the pollen grains were similar to spherical or oblong,three-lobed round in polar view,small in polar view,with clear reticulate ornamentation on the surface of the outer wall,and the reticulate ridges were densely covered with uniform verruculose protuberances,and there were many reticulations with different shapes and sizes.Conclusion:The method of this study is simple,environmentally friendly,accurate and reliable,and can provide a reference basis for the identification of the authenticity of Epimedium species.
