Iris reticulata of sect. Reticulata from subg. Hermodactyloides in Iraq have been circumscribed based on morphological characters long time ago. Recent work, carried out in neighbouring countries (Turkey and Iran), added the new sect. Zagrica, which includes four new species. No molecular study has been performed yet to confirm the status of this subgenus. In this work, a phylogenetic study of the subg. Hermodactyloides was carried out by using internal transcribed spacer (ITS) region as well as morphological traits, with the aim to examine this subgenus in Iraq. Molecular data indicate that a new section is diverged from Hermodachtyloides and should be added to vascular flora of Iraq as a second section named Zagrica. This outcome is consistent with the morphological description. This work also implies that leaf transverse section should be considered as main morphological characters to be taken into account to separate the Reticulata section from Zagrica which has the same taxonomical value as the position of ovary (above ground or subterranean).

This study demonstrates that the vascular flora of the Rangpur district area consists of 825 species under 537 genera and 139 families. The pteridophytes and gymnosperms are represented by 25 and seven species, respectively, whereas the angiosperms by 793 species including 582 species of dicotyledons (Magnoliopsida) and 211 species of monocotyledons (Liliopsida). Poaceae with 67 species, representing 8.12% of the flora, is appeared as the largest family, and followed by Asteraceae, Fabaceae, Araceae, Malvaceae and Euphorbiaceae that collectively constitute 17.94% of this flora. Persicaria comprising 10 species is recorded as the largest genus, and followed by Ficus, Euphorbia, Solanum, Albizia and Brassica. About 59.71% taxa of this flora are herbs, 21.71% trees, 14.72% shrubs and the rest are palms, lianas, and bamboos. Erect herbs forming 35.22% of the flora comprise the most common life-form. In this flora, almost 64.29% taxa are native and the rest 35.71% are exotic. Nearly 62.61% taxa of the flora are found in wild, 26.90% as planted and 10.49% as cultivated. About 35.46% of the species commonly occur throughout all upazilas of this district. Most of the species are harboured in fallow lands, roadsides, gardens, and homesteads. All species of this district flora are known as economically useful. Most of its habitats and ecosystems are exposed to different threats. Adequate measures with effective management plans should be adopted and implemented for the sustainable use, improvement and conservation of this precious flora. Bangladesh J.

A complete catalogue of the vascular flora of the North Carolina Outer Banks is presented. Rarity, habitat, distribution within the Outer Banks, and earliest and latest specimens are given for each taxon. The flora contains 1020 species and infraspecific taxa, plus an additional 80 taxa that lack voucher specimens. Some 770 taxa are considered native; 250 non-native. Fifty-one taxa reach their northern range limit on the Outer Banks; 11 their southern limit. Fifty-five taxa are listed as rare in North Carolina; one of them also listed Threatened by the U.S. Fish and Wildlife Service. Twenty-four natural communities are described and assessed for vulnerabil-ity to sea level rise. Prior botanical research is listed chronologically.

Djavolja Varoš, one of the most atractive natural geological formations of errosive origin in Serbia, is situated in the south of the country, and protected by national legislation as a Natural Monument. The taxonomic and ecological analysis of flora in this area has not been processed yet, so we performed a survey of flora in this locality. Plant species were collected, herbarized, and taxonomic and biological spectrum analyses were conducted. This field study revealed that the vascular flora of the study area was made up of 130 constituent species, which belonged to 81 genera and 41 families. The biological spectrum of the flora is characterised by high presence of hemicryphytes (38%) and geophytes (20%).

As a result of the performed research of the Ruy mountain flora, 261 plant species were found and established. These refer to 176 genera and 57 families. There was a floral analysis performed, which determined 116 medicinal plants species. The examined local flora has 12 Balkan endemites and 19 relict species. There is one species with endangered conservation status – Galanthus elwesii Hook. f. There were 7 species determined, which fall within the scope of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). The plant species found were examined and determined in terms of biological types. The floral complex of this local flora was also determined.

The tradition of floristic studies in Italy has made it possible to obtain a good knowledge of plant diversity both on a national and regional scale. However, the lack of knowledge for some areas, advances in plant systematics and human activities related to globalization, highlight the need for further studies aimed at improving floristic knowledge. In this paper, based on fieldwork and herbaria and literature surveys, we update the knowledge on the Italian vascular flora and analyze the floristic similarities between the administrative regions. Four taxa, all exotic, were recorded for the first time in Italy and Europe. In detail, Elaeodendron croceum, Kalanchoë blossfeldiana, and Sedum spathulifolium var. spathulifolium were found as casual aliens, while Oxalis brasiliensis was reported as historical record based on some herbarium specimens. Furthermore, Kalanchoë laxiflora was confirmed as a casual alien species for Italy and Europe. Status changes for some taxa were proposed at both national and regional levels, as well as many taxa were reported as new or confirmed at the regional level. Currently the Italian vascular flora comprises 9150 taxa of which 7547 are native (of which 1598 are Italian endemics) and 1603 are exotic at the national level. The multivariate analysis of updated floristic data on a regional scale showed a clear distribution along the latitudinal gradient, in accordance with the natural geographical location of the regions in Italy. This pattern of plants distribution was not affected by the introduction of alien species. Despite some taxonomic and methodological issues which are still open, the data obtained confirm the important role of floristic investigations in the field and in herbaria, as well as the collaborative approach among botanists, in order to improve the knowledge of the Italian and European vascular flora.
