Abstract:
OBJECTIVETo study the pollen morphology of ten species of Achillea.
METHODThe pollen morphology of ten species of Achillea was examined with LM and SEM.
RESULTThe pollen grains were usually 3-colporate, subspheroidal. The exine ornamentation consisted of verrucate, spinulate and foveolate. But some differences in size, colpae and exine ornamentation were found.
CONCLUSIONThe slight differences of the pollen morphology are useful to some extent for the classification of the ten species of Achillea.
