Total phenolic, flavonoid, condensed tannin and iridoid content, as well as antioxidant capacityin vitro,were determined spectrophotometrically in methanolic extracts of different plant parts of the Mediterranean medicinal plantGlobularia alypumL. and three widespread European species of the same genus:G. cordifoliaL.,G. meridionalis(Podp.) O. Schwarz andG. punctataLapeyr. In order to consider possible environmental influences on the production of specialized metabolites, each species, exceptG. alypum, was collected from three different natural populations. Great variations in the amounts of specialized metabolites were observed among different plant parts and species. For example, total phenolic content ranged from 10.13 (G. punctata, flowers) to 44.90 (G. cordifolia, flower stems) mg gallic acid equivalent g−1dry weight. Moreover, great differences, attributed to location-specific environmental factors, were observed among different populations of the same species. For example, a strong positive correlation was observed among mean monthly temperatures and total phenolic contents in the leaves of studiedGlobulariaspp. (r = 0.75, p = 0.019). However, despite these differences, all species were rich in bioactive substances when compared toG. alypum, especially in their aerial parts. A very good positive correlation was observed between total phenolic content and DPPH radical scavenging capacity (r = 0.86, p < 0.001)/ABTS radical scavenging capacity (r = 0.83, p < 0.001). The results obtained show thatG. cordifolia,G. meridionalisandG. punctataare rich in bioactive substances, providing support for their pharmaceutical utilization. Further investigations are needed to verify the possibility of their medicinal use.

In this paper, an attempt is made for the first time to present a complete list of the alien vascular flora of the urban area of Mostar, Bosnia and Herzegovina. A total of 152 plant taxa were collected, which equals 15.72% of the complete flora of Mostar. The most common families are Asteraceae s.l. (18.54%), Poaceae (11.26%) and Fabaceae (9.93%), while therophytes (59.60%) are the most abundant life form. According to the naturalisation status, the most dominant are casual taxa (44.37%). Most non-native taxa originate in the Americas (39.07%), followed by those that originate in Asia (23.84%). Many of these species are herbaceous annuals, many of which are regarded as weeds.

The flora of the town of Blagaj was observed and researched during the vegetation seasons from 2004 to 2014. In total, 723 plant taxa from 102 families are presented in the list, 577 of which are newly found, while the presence of 14 previously reported taxa was not confirmed. Alien taxa present exclusively in culture were not analysed in this work. The most common family is Asteraceae s. l. (11.76%), followed by Poaceae (9.82%), Fabaceae (7.75%) and Lamiaceae (6.50%). The predominant life-forms are therophytes and hemicryptophytes with 265 and 264 taxa, respectively (36.65% and 36.51%). The floral elements spectrum shows the strong prevalence of Mediterranean plants (29.46%), while Central European plants are almost absent (0.41%). A total of 38 taxa are found on the National Red List, while 27 taxa are classified as invasive.

Downy thorn-apple Datura innoxia Mill is native in southwest U.S.A. and Mexico. It has been recorded as a new alien species to the vascular flora of Bosnia and Herzegovina. In Bosnia and Herzegovina, D. innoxia is reported from two localities in the city of Mostar where the species has escaped cultivation and established small populations in surrounding ruderal habitats including waste land. The species is toxic to animals and humans. The paper presents a short morphological characteristic and photographs as well as the distribution of the species in the Bosnia and Herzegovina.

The bibliography of alien plant taxa in Bosnia and Herzegovina is not abundant. There are no published complete lists or analysis of alien flora in Bosnia and Herzegovina as a whole. Therefore, information on the alien species present in Bosnia and Herzegovina is incomplete. Only sporadic and, in many cases, accidental records concerning adventive/neophyte plant taxa exist. In this study alien flora of the Hutovo Blato Natural Park was analysed. It numbers 49 taxa, which equals 7.67% of the complete flora of Hutovo Blato Park. Alien taxa present exclusively in crops were not analysed in this work. The most common family is Asteraceae s. l. (10 taxa, 20%), followed by Poaceae (9 taxa, 18%). The predominant life forms are therophytes (63%) and phanerophytes (17%). According to the naturalization status, the most dominant are invasive taxa (47%). Most non-native taxa originate in the Americas (51%), followed by those that originate in Asia and Mediterranean, each 20%. Many of these species are herbaceous annuals, many of which are regarded as weeds.

Two new neophytes, Oenothera fruticosa L. and Phacelia campanularia A. Gray were discovered in the early summer of 2021 during fieldwork in the vicinity of Olovo (Central Bosnia). They are native to North America, but they have been introduced to some areas beyond their natural range. This is the first record of those species for Bosnia and Herzegovina. Brief information on the species distribution in Bosnia and Herzegovina, as well as a discussion of the alien and invasive status in the country are provided. All recently found localities are restricted to road verges and, apparently, reflect a recent human assisted colonization of the species. Judging from the literature and observations in the field both species should be considered casual, non-invasive species in Bosnia and Herzegovina. The text is illustrated with photographs from the new localities of both species.
