摘要
目的:建立尖尾芋和海芋叶形态-脉序图谱鉴别方法,为药材鉴别、质量标准制定及深层次开发利用提供新的资料。方法:在植物地理学考察和原植物鉴定的基础上,以叶形态-脉序图谱法观察尖尾芋和海芋叶的形态与各级脉序。结果:尖尾芋和海芋的主要区别点在于尖尾芋叶片宽卵状心形,叶基心形或圆形,先端骤尖,侧脉5～8对,侧脉整体走向为斜向上方并且向中肋靠拢;海芋叶片阔卵形,叶基耳形,先端短尖,侧脉9～12对,侧脉整体走向趋于向左右两侧延伸。结论:叶形态-脉序图谱可作为尖尾芋和海芋的主要鉴别特征之一,用于其药材识别和质量标准的制定。
Objective：To compare and identify leaf venation characteristics of Alocasia cucullatat and A.macrorrhiza.Method： An identification method for LMVP（leaf morphological-venation pattern for identification Chinese herbs） was established and applied.Result： The difference between A.cucullatat and A.macrorrhiza is as follows： A.cucullatat： leaf blade is oval-cordate,leaf base cordate or round,leaf apice cuspidate,lateral veins 5-8,inclined up and close to the central;A.macrorrhiza： leaf blade is broad-ovate,leaf base auriculate,leaf apices mucronate,lateral veins 9-12,tend to the left or right side extension respectively.Conclusion： The leaf morphological-venation pattern can be used to identify the characteristic of A.cucullata and A.macrorrhiza and provide basis for the establishment of its quality standard.
