Abstract: The purpose of the present paper is to discuss the systematic position of the genus Schnabelia originally proposed by H. Handel-Mazzatti in 1921, who considered it as belonging to the family Verbenaceae, a point which he further emphasized in 1936. However, in his paper on the Chinese verbenaceous plants (1932), Prof. Pei Chien thought the genus should be removed from Verbenaceae into Labiatae and allied it with such genera as Ajuga and Teucrium on the ground that it also has deeply lobed ovary. Since then botanists on Chinese plants, such as Prof. Y. Z. Sun, F. C. How, etc. have always considered Schnabelia Hand.-Mazz. as a genus of Labiatae. The present writer has recently studied the genus, comparing its morphology of ovary, calyx lobes, pedicels, pollen grains, etc. with a number of verbenaceous genera, and comes to the conclusion that the genus should belong to Verbenaceae as H. HandelMazzatti first proposed and that it is closely allied to the genus Caryopteris, especially C. nepetaefolia (Benth.) Maxim. Moreover, he considers that the deeply lobed ovary is not at all a good character even for generic separation, for several genera in Verbenaceae, such as Caryopteris, Clerodendron, just like Teucrium and Ajuga of Labiatae, also have deeply lobed ovaries. From the ample herbarium material, the present writer discovered for the first time that the genus Schnabelia has two types of flowers, cleistogamous and chasmogamous. The original founder of the genus did not know this peculiar floral character, as not mention of it was made in the generic diagnosis. Chienodoxa Sun (1951) proves to be the present genus, which is based upon the cleistogamous type of flowers of an allied or perhaps the same species.
