This book describes the taxonomic and systematic studies of some
important medicinal plants of Dir valley, Pakistan. The information
regarding morphological and palynological characterization along with
pollen fertility estimation of about 50 species of 37 genera belonging
to 7 families are studied in detail. Morphological characters help in
understanding the adaptation and differentiation in particular
environment while the pollen morphology and its fertility estimation is
closely related to its function and many of the pollen features helped
the species to adapt the life on particular geography and disperse its
pollen in successful manner to fertilize the egg for the production of a
new plant. The data derived from the research can contribute to the
taxonomy of these families and may provide new dimensions towards
further research in the discipline of morpho-palynological systematics.
