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.
