SEED MORPHOLOGY AND CLASSIFICATION OF IMPATIENS (BALSAMINACEAE)

Seed coat morphology was observed through SEM for 65 species and 10 sections of Impatiens. Several types of seed coat are recognized in this study. On the basis of comparison with other characters such as chromosome numbers, floral characters and seedling morphology, systematic problems concerning Impatiens are briefly discussed.
