Identification of Characters of Leaf Venation of Alocasia cucullatat and Alocasia macrorrhiza
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 herhs) 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 vein* 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. macrorrhiia and provide basis for the establishment of its quality standard.
