本文研究了榕树属3个亚属33个分类群叶片中草酸钙和碳酸钙晶体的类型和分布，以推测其亚属间的亲和力。55个性状的数值分析将该类群划分为13个类群。计算了后者的大小与它们所包含的分类群数量的关系。一些结果群由来自不同亚属的分类群组成。就目前的资料而言，与前人的研究一致，弹性榕和本雅榕的花叶变种较好地提高到花叶榕和花叶榕的特定水平。分别。（©2004 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim）
The type and the distribution of calcium oxalate and calcium carbonate crystals were investigated in the leaves of 33 taxa of Ficus belonging to the three subgenera Urostigma, Ficus and Sycomorus for a speculation to the inter-subgeneric affinity. Numerical analysis of 55 characters grouped the taxa under 13 groups. The sizes of the latter with respect to the number of taxa they contain were calculated. Some resultant groups comprised taxa from different subgenera. So far as the present data are concerned and in agreement with previous workers, the var. decora of Ficus elastica and var. comosa of Ficus benjamina are better raised to the specific levels F. decoraHort and F. comosaRoxb. respectively.
