摘　　要：目的:鉴别苗族和黎族常用药物瘤果槲寄生。方法:形态学、组织学和紫外光谱方法。结果:茎枝黄色,呈二歧状分枝,叶具3～5条基出脉。茎横切面,表皮外壁特厚,并向外突起呈乳突状;石细胞分布于皮层和韧皮部,胞腔内常含草酸钙方晶;中柱鞘纤维和木纤维的壁均特厚,具缘纹孔导管内壁有的具三生螺纹增厚;叶肉不分化,含簇晶(非草酸钙结晶),平轴式气孔分布于叶的上、下表面,副卫细胞窄小。本种表面无毛茸。结论:上述形态学和组织学特征可用于本种的鉴别,紫外光谱法也是一个简便的方法。Objective:To identify Herba Visci Ovalifolii,a Chinese medicinal materials used in Li and Miao nationalities. Methods:Morphological, microscopical and UV spectral methods. Result: Dichotomous branch with a yellow surface, with leaf of 3-5 acrodromous veins o-riginating at the base of the leaf. In transverse section, the thick outer wall of the epidermis of stem projecting like nipple; stone cells contain frequently a prismatic crystal of calcium oxalate, often occur in the cortex and phloem of the stem.
