The objective of this study is to inventory the flora of the Ouled Bechih forest (Algeria) with a quantitative and qualitative analysis through significant parameters. This study allowed the identification of 27 species belonging to 26 genera and 17 families. The results show an important diversity of the regional flora which is essentially dominated by the Asteraceae, Fabaceae, Fagaceae and Rosaceae. Hemicryptophytes and geophytes dominate the biological spectrum of the flora of this forest, which is morphologically characterised by the dominance of perennial herbs. The analysis of the chorological types shows the predominance of the Mediterranean element.

For the management and sustainable use of natural bio-resources it is necessary to quantify and valorize this heritage. In the case of the floristic diversity of Acacia tortilis, the only natural woody stand in Bechar-Algeria, scanty studies have been undertaken. Hence in this study, the general overview of the flora diversity state in the 58 plots of 9 stations was made by the analysis of various indexes: Shannon, Simpson, species evenness, floristic richness, disturbance index, biological and biogeographically spectra. We listed 103 species belonging to 37 families and 85 genus, the important plants belonged to the Asteraceae and Brassicaceae. The most important species are: Pulicaria crispa, Asteriscus graveolens, Launea arborescens, Matricaria pubescens, Moricandia arvensis, Farsetia aegyptiaca, Zilla macroptera. The biological spectrum indicated a dominance of the Chamaephytes and the predominance of the Therophytes; the phytogeographic spectrum showed an important endemism (44%) in which 36% species belong to the SaharoArabian element; The Shannon, Simpson, and Evenness diversity indices, were relatively high, thereby indicating a diversity variation between the stations, witch increased South towards North. It was prominent in Zouzfana, Taghit, and Abadla stations, and the higher values of disturbance Index reflected the greater level of anthropization in these courses. The future accumulation of this regression, many risk loss of the last naturally wall of desertification, biodiversity, national economy and sand advancement. Therefore, it is recommended to apply pastures protection, pastoral charge control, and elaborate an environmental value of this species.

The current study aims to quantify and evaluate the Tetraclinis stands (Tetraclinis articulata (Vahl.) Masters) richness and floristic diversity at Kharouba Site of Biological and Ecological Interest (SBEI). The 150 floristic surveys conducted in the site allowed us to inventory 143 species distinguished with rare taxa majority that are distributed over 54 families and 123 genera. This reduced number of taxa reflects the alarming biodiversity deterioration of the SBEI. The study also enabled us to define the biological spectrum of the study area that is characterized by a significant abundance of Therophytes.

Field surveys were carried out to evaluate the floristic diversity and biological spectrum of Lower Tanawal, District Abbottabad in different seasons during 2016-2018. This study area was divided into 80 stands on the basis of physiognomy of the vegetation. Life form classes and leaf spectra were classified following Raunkiers methodology. In total, 286 plant species belonging to 86 families were recorded, out of which herbaceous growth form dominated the study area with 187 species, followed by shrub with 54 species. Among all 86 families, Asteraceae was found to be the most dominant family with 25 species, followed by Fabaceae with 24 species and Rosaceae with 20 species. Based on life form classes, Therophytic life form was the leading class with 113 species (39.5104%), followed by Nanophanerophytes with 45 species (15.7342%). In leaf size spectra, Microphylls dominated the flora with 88 species (30.7692%), followed by Mesophyll with 81 species (28.3216%). This study shows the complete floristic composition that may be important as reference work for future ethnobotanical, ecological and conservational studies.

Stachys Linnaeus (1753: 580) (Lamiaceae) is a genus composed by annual/perennial herbs and small shrubs, with sessile or short-stalked flowers arranged in axillary clusters on the upper part of the stem forming raceme or spike inflorescences, and very variable calyx that represents an important trait for systematics. It is a subcosmopolitan genus, which includes approximately 370 species (Harley et al. 2004), mainly distributed in the Mediterranean and South-West Asia warm temperate regions.

The forest of Bissa is a Mediterranean ecosystem, characterized by a high floristic diversity. In order to assess the floristic diversity in this forest, 133 floristic readings were conducted in this area between 2013 and 2017. As a result, it was possible to identify 151 species, 125 genus and 54 botanical families, with a clear dominance of Asteraceae, Fabaceae and Poaceae.  Biologically, this ecosystem was mainly dominated by therophytes (37%). Physiognomically, the phanerophytes were the most dominant types, whereas in term of phytogeography this forest was dominated by the Mediterranean type (50%). According to Shannon-Winner index, this area was characterized by a relatively low diversity (1.3 bit / ind), with a clear dominance of a few species. Finally this forest was relatively disturbed (42%) and under a strong anthropozoic influence.

The present study evaluated the floristic diversity and biological spectrum of Muscat Governorate, Sultanate of Oman. Heterogeneity of geology, topography and climatic conditions create a diverse array of habitats across the 3,500 km2 study area, supporting a range of vegetation types. Floristic studies were conducted across 42 sites spread across various habitats such as sand dunes, alluvial plains, gravel plains, wadis, saline dunes, coastal areas, farms and plantations. A total of 264 species belonging to 183 genera and 54 families of angiosperm were documented during sampling the vegetation from different wilayats of the Governorate. Maximum number of species belonged to family Fabaceae (14%), followed by Poaceae (12%), Asteraceae (9%), Apocyanaceae and Convolvulaceae (3.66% each), Boraginaceae, Euphorbiaceae, Zygophylaceae (3% each). The biological spectrum was represented almost equally by therophytes and chamaephytes (30% each), followed by phanerophytes (19%), hemicryptophytes (13%), geophytes (4%), liana (3%), and helophytes (1%). The dominance of therophytes and chamaephytes reveals a thero-chamaephytic phytoclimate for the area. Different habitats are characterized by specific plant assemblages, but some species such as Acacia tortilis, Prosopis cineraria, Tetraena quaterense, Dipterygium gluacum, Aerva javanica, due to their broad ecological tolerance and adaptations, inhabit more than one habitats, while some species are just confined to certain parts of a single habitat.
