To identify the botanical origin of the commercial Chinese crude drug "Roucongrong (肉〓蓉)," a pharmacognostical study of genus Cistanche plants in Asia was carried out. In this study, the morphological and anatomical characteristics of specimens of three Cistanche species (C deserticola, C. tubulosa and C. salsa) from China and other Asian countries, and six commercial samples of the crude drug from China were examined. The results were as follows: (I) These three species could be distinguished from each other by the arrangement of vascular bundles in the transections of the stems, the morphology of vascular bundles in the scale leaves and the external morphology of the seeds. (II) C. tubulosa from China and Pakistan differ from each other in the size of plants and the longitudinal arrangement of vascular bundles in the stems and the scale leaves. (Ill) Six crude drug samples from Neimenggu, Ningxia and Xinjiang provinces of China were shown to be derived from either C. deserticola or C. tubulosa.
