[Identification of six species of medicinal Diospyros plants based on leaf macro- and micro-morphology].

To establish a method for the identification of five species and one variety of medicinal plants from Diospyros, their leaf veins, epidermis, anatomic and powder characters were observed and compared with macro-morphological and microscopic methods. The results indicated the differences of secondary and tertiary veins among those Diospyros species. The single cell non-glandular hair and glandular hair exist in most species' epidermis while stone cells were only found in the leaf powders of two species.
