Abstract: The present paper deals with the classification on the genus Boschniakia C. A. Mey. ex Bongard (Orobanchaceae). The taxonomic history of the genus Boschniakia, which was described by C. A. Meyer and A. H. G. Bongard based on the type species B. glabra [=B. rossica (Cham. et Schlecht.) Fedtsch.] in 1833, is reviewed. The genus Xylanche was separated by G. Beck (1890) from Boschniakia on the basis of its ebracteole flowers with 3 - 5-dentate or subentire calyx and 3 carpelled pistil. Having carefully studied the morphological characters of these taxa, however, the author finds that these characters are not reliable and quite variable in Boschniakia and Xylanche. The seed coat in B. rossica (Cham. et Schlecht.) Fedtsch. and X. himalaica (Hook. f. et Thoms.) G. Beck (=B. himalaica Hook. f. et Thoms.) under scanning electron microscope (SEM) were also examined. There exist striking differences not only in seed coat but in size and form, which can serve, in author's opinion, as characters for delimitating species.

摘要： 本文详细比较了草苁蓉属和丁座草属(Xylanche)植物的形态特征，并在扫描电镜下观察了它们的种皮纹饰。发现G．Beck(1890)建立丁座草属时所依据的花部性状并不可靠，这些性状，尤其是花萼分裂度和心皮数目，本身就有变异。因此，作者将丁座草属归并人草苁蓉属(Boschniakia)中。
