Watthana&S. W. Chung];独花兰属为单种属,仅独花兰(Changnienia amoena S. S. Chien) 1种,该种为中国特有种,广西首次记录。该文还提供了新记录属和种的形态描述和图片。展开更多

Having deduced the relations between the modified-iterative method and Chien's perturbation solution, we obtained the conclusion that the convergent regions of the two methods are the same.展开更多
