Identification Characters of Leaf Morphological and Venation Pattern of Houttuynia cordata with Its Confused Herb Gymnotheca chinensis
摘要
Abstract
Objective:To study the identification characters of Houttuynia cordata and its confused herb Gymnotheca chinensis and establish an identification method.Methods:LMVP (leaf morphological-venation pattern for identification Chinese herbs),and QAERM (quantitatively analyze and evaluate reliability for the method of identification Chinese herbs) were applied for the study.Results:Both venations were brochidodromous-acrodromous and arising from the mid-petiole or the upper section of petiole.The main characteristic of the leaf of Houttuynia cordata:surface with small gray-white stoma protuberances; Ligulate process of stipule-petiole sheath were clear; Primary veins 7 or 5; The innermost pair of primary vein closed up the top of the sinus at blade base or above sinus,and the section of closed vein was straight; Emitted a smell of fish when fresh leaf was kneaded into pieces.The main feature of the leaf of Gymnotheca chinensis:no small gray-white stoma protuberances; Ligulate process of stipule-petiole sheath were not clear; Primary veins 5; The innermost pair of primary vein closed into the sinus at blade base,and the section of closed vein was slightly curve; No smell of fish.With the mentioned key differences,the both plants could be successfully identified from each other.The accuracy of i-dentification results (AC) was 100% ,the repeatability of identification results-,agreement rate for observation ( ARO) was 100% and Kappa value was 1.00.Conclusion:The established method is simple,rapid,economic and reliable.关键词
