The present study dealt with the pollen grains of 11 species of the genus Valerianella

Miller within the family Valerianaceae which have been collected within the field trips

during spring and summer season of year 2014 (about 20 trips) from the different

districts in Kurdistan of Iraq. From the used characters that had a role in the separation of

some species were the pollen shapes, sizes, surface sculpture and the end shapes of the

colpi, generally the pollens had a limited role in the species separation. Photographs have

been taken for the polar and equatorial views of the pollen grains. The species were

Valerianella chlorostephana Boiss., V. coronata (L.) DC., V. dactylophylla Boiss. &

Hohen, V. discoidea (L.) Lois., V. kotschyi Boiss., V. lasiocarpa (Stev.) Betcke,

V.muricata (Stev.) Baxt., V.oxyrhyncha Fisch & Mey, V.pumila (L.) DC., V. tuberculata

Boiss. and V. vesicaria (L.) Moench.
