title: [Pharmacognostical studies on Prunella vulgaris and Ajuga decumbens].
abstract: Ajuga decumbens Thunb. is superficially similar to Prunella vulgaris Linn. and has been used as a substitution of the latter for along time. Systematical studies on external and internal structure were carried out on the two species. By means of studies on root, stem, leaf, flower and seed, morphological characters of histology were examined and described.
