Micromorphological characters of leaf epidermis were investigated in 69 species of using scanning electron microscopy. Sculpture of epidermis varies from smooth to verrucose and rugose in the genus. The abaxial epidermis of some species bears papillae, whereas the adaxial surface uniformly lacks the papillae. Sculpture type of epidermis and density of papillae are generally found to be stable characters at a species level. The infraspecific variation of epidermis sculpture, where present, ranges from smooth to verrucose or from verrucose to rugose. Micromorphological characters of leaf epidermis are shown to have potential taxonomic significance in ; in combination with the type of shoot structure, they allow to subdivide the species into 13 groups. The groups are largely incongruent with floral morphological traits. An identification key to the studied species of based on vegetative characters (gross leaf and shoot morphology and characters of leaf epidermis) is presented.
利用扫描电子显微镜对69种[植物名称未给出]的叶片表皮微形态特征进行了研究。该属植物表皮纹饰从光滑到瘤状和皱纹状不等。一些物种的叶下表皮有乳头状突起，而上表皮则普遍没有乳头状突起。表皮纹饰类型和乳头状突起密度在物种水平上通常是稳定的特征。表皮纹饰的种下变异（若存在）范围从光滑到瘤状或从瘤状到皱纹状。叶片表皮的微形态特征在[植物名称未给出]中显示出潜在的分类学意义；结合枝条结构类型，可将该物种细分为13个组。这些组在很大程度上与花的形态特征不一致。给出了基于营养特征（叶片和枝条的宏观形态以及叶片表皮特征）对所研究的[植物名称未给出]物种的鉴定检索表。
