The paper propose nine new nomenclature combinations and indicate eight new synonyms. There are 12 taxa (species and subspecies) of vascular flora which are new for the flora of Serbia (of which nine are autochthonous and three 88 N iketić, M. etal. : Annotated Checklist of Vascular Flora of Serbia II allochtonous plants). An old or unreliable literature records for three autochthonous and one allochthonous plant in the flora of Serbia has been confirmed. Eight plant taxa are a novelty for proper Serbia, Vojvodina, or Kosovo and Metohija, and for three plants, presence in certain administrative units in Serbia has been proved. The last part of the paper contains information on eight taxa whose presence in Serbia or in its territorial units has been refuted.

Economic justification of organic honey production is analyzed in the paper. The emphasis was placed on specific revenues and expenses that occur in organic honey production, and economic justification was examined by calculating indicators of economic efficiency, profitability and labour productivity. Based on the collected data, a calculation of production was made and a profitability threshold was established, which is achieved with 38 bee colonies, or with production volume of 570 kg of honey. Farms with more colonies have better indicators of production success. The expenses arising from the transition from conventional to organic production will be most quickly covered by farms with 200 bee colonies that generate enough income from organic honey production to operate positively in the third year of organizing such production.
