• Abstract: In order to understand and confirm the problems of Dendrobium officinale in China, we have observed and compared the cultivation of D. officinale for more than 10 years, it was found that the plant morphology of D. officinale in all the cultivation areas are significantly different; With these questions, the authors compared the stem color, leaf width and size, the width and color of the nodes on stalk, the length and color of the internodes respectively by pictures and tables, the differences between the different germplasm resources were proved. The external morphological differences of D. officinale were expounded. The identification of germplasm resources of D. officinale was suggested in China. 为了深入了解、确认中国铁皮石斛种质存在的问题，通过十多年的铁皮石斛栽培观察与比较，发现在所有铁皮石斛栽培地区的植株形态都存在明显差异，笔者带着这些问题，分别对茎秆颜色、叶片宽窄和大小、茎杆上节的宽窄和颜色、节间的长短和颜色，以图片和表格的方式比较，证明了各种质资源之间的差异；阐述铁皮石斛这个种的外部形态学差异；并对中国境内铁皮石斛种质资源提出鉴定意见。
