    ABSTRACT: Helianthemum marmoreum is described as a new species from the central part of the Balkan peninsula (R. Macedonia). It inhabits rocky marble and limestone slopes and pastures at moderate altitudes of 240-1400 m. The closest relative is H. hymettium which is endemic to southern Greece.

    ABSTRACT: This paper presents six plant species rediscovered for flora of Serbia after they were considered extinct in this territory. Therefore they were included in the publication “Red Book of Flora of Serbia 1” in the category of Extinct taxon (EX). These six species are: Aconitum anthora L., Aldrovanda vesiculosa L., Chorispora tenella (Pallas) DC., Dracocephalum ruyschiana L., Juncus capitatus Weigel and Linum nodiflorum L. According to new IUCN criteria, the threat status estimation were made and the species were placed in the group of critically endangered within the territory of Serbia. New field observations of population stage and data of distribution are presented for 21 plants that were included in the category of critically endangered taxa in this publication. Population size of plants on the studied localities and new threatened status were presented for each taxon.

    ABSTRACT:  Plant regeneration of carnation species Dianthus ciliatus ssp. dalmaticus and Dianthus giganteus ssp. croaticus was achieved through micropropagation from apical and nodal segments culture on MS2. Shoots multiplication was successful on the same medium via axillary buds. Th ere were diff erences between multiplication index (MI) of shoots originating from apical and nodal basal stem segments. Nodal segment shoots had a better MI (D. ciliatus ssp. dalmaticus = 7.86; D. giganteus ssp. croaticus = 0.68) than apical ones (D. ciliatus ssp. dalmaticus = 6.94; D. giganteus ssp. croaticus = 0.50). Shoots of both species were rooted on MS0 without hormones, MS3 and MS4. Adventitious buds (AB) and somatic embryo like structures (ES) were formed aft er the transfer of green-yellow callus from MS5 to MS6. Further development and multiplication of AB and ES were achieved on medium MS7. Plants formation was brought about by micropropagation of shoots, organogenesis and/or somatic embryogenesis. In vitro plantlets of both carnation species were planted in rocky garden of the Belgrade Botanical Garden ‘’Jevremovac’’ where they bloomed. Subsequently, these in vitro plantlets will be reintroduced in natural environment.
