Pollen morphological study of the dicots wetland plants of Southern Marshes of Iraq

Abstract EN

Palynological features of the pollen grains of Dicots wetland plants of the Southern Marshlands of Iraq were studied.

Forty nine species belong to twenty five families were investigated.

The results showed that there were significant difference and high diversity in shape, size, ornamentation and apertures of the pollen grains of most genera and species studied.

Most families and genera have their own characteristic pollen types.

On the basis of ornamentation and apertural types, nineteen distinct pollen types were recognized.

Pantoporate pollen grains were showed in several families such as Chenopodiaceae and Amaranthaceae.

Most species contain three colpi as in Bacopa monniera, while Myriophyllum spicatum contains 4-5 clopi, but many species contained colp and pore as in most of Dicots species as in Compositae.

Ornamentations were varied from psilate in the Utricularia australis to echinate in some species of Compositae.
