The position with Ceratophyllum is supported by a shift from latrorse to introrse or extrorse anthers (in both taxa, the thecae are shifted toward one surface, but whether this is abaxial or adaxial is unknown).
Anthers are 2.5-3.0 mm long and 1.0-1.5 mm wide, dorsifixed, reddish pink in colour, bilobed and tetralocular with dehiscence-slit facing the interior of the flower (introrse).
Despite that cultivated varieties are autogamous, buzzing improves self-pollination, since stigmas are introrse and most of the pollen grains released from the anthers are deposited on the stigma of the same flower (King and Buchmann, 2003; Greenleaf and Kremen, 2006).
The anthers are located on the inner face of this tube and show longitudinal introrse dehiscence.
This group which started its operations against the foreign incursion in Iraq, went on to demonstrate a much more introrse facade.
