                     I- Common Morphological Characters
                 •  They are usually cremocarp either entire or separated into their mericarps.

                 •  At  the  apex  of  the  fruit,  there  may  be  five  small  inconspicuous  sepals
                     (Coriander), and in the center are the two styles surrounded below by disc-
                     like nectary forming the stylopod.


                 •  Each mericarp has two surfaces, a flat surface called the commissural surface
                     and a convex one called dorsal surface.

                 •  The dorsal surface shows 5 raised ridges over the vascular bundles called
                     primary ridges between which may be found four ridges over the secretory
                     canals  and  called  secondary  ridges.    Primary  ridges  are  mostly  more
                     prominent except in Coriander where the secondary is more prominent. Only
                     primary ridges are present in some fruits (Fennel, Anise & Caraway).

                 •  The commissural surface shows two brownish longitudinal bands over the
                     region of the secretory ducts separated by lighter area over the position of
                     the raphe.
