草酸钙结晶在植物界分布十分广泛,其类型、分布部位、密度及大小等特性,均在植物分类、生药及其原植物鉴别中具一定价值。草酸钙结晶类型在具体植物种类中通常是稳定的。但作者在观察研究中发现,其密度(多少)、大小、甚至存在部位却与药用植物生境及 Calcium oxalate crystals are widely distributed in the plant kingdom, and their types, distribution locations, density, and size are all of certain value in the classification of plants, identification of crude drugs and identification of their original plants. Calcium oxalate crystal types are generally stable in specific plant species. However, the authors found in the observational study that the density (how many), size, and even the presence of parts are related to the habitat of medicinal plants and
