Abstract
This paper presents further results of studies on pollen morphology of the family Caprifoliaceae. Besides detailed descriptions of 6 species of genera Linnaea and Lonicera, series of LM and SEM microphotographs are included. All examined species have pollen grains of medium- or large-sized, with oblate forms, echinate (microechinate) ornamentation and short ectoaperture, often margined by costa. Length of spines and density of their distribution on the tectum allow to distinguish Linnaea and Lonicera subtypes. The key for determination of 11 Caprifoliaceae species, based on pollen morphology is proposed too.
