Background & Aim: Iran with about 8000 plant species and 1728 endemic species; is one of the most important sources of medicinal plants. Dracocephalum kotschyi Boiss., belonging to the Lamiaceae family, is one of the endemic plants in Iran. It grows in regions of Chaharmahal and Bakhtiari, Esfahan, Gorgan, Mazandaran, Hamedan, Kermanshah, Lorestan, Tehran, Fars and the northern heights of Semna...

The Caribbean archipelago is a region with an extremely complex geological history and an outstanding plant diversity with high levels of endemism. The aim of this study was to better understand the historical assembly and evolution of endemic seed plant genera in the Caribbean, by first determining divergence times of endemic genera to test whether the hypothesized Greater Antilles and Aves Ri...

Thirty extracts obtained from 10 endemic plant species belonging to 8 plant families used in the traditional medicine in Socotra have been tested for cytotoxic activity against FL-cells. Extracts of Eureiandra balfourii and Commiphora ornifolia showed the strongest activity against FL-cells with IC(50) < 10 microg/ml and 39.3 microg/ml respectively.

The ragged topography created by orogenesis generates diversified habitats for plants in Taiwan. In addition to colonization from nearby mainland China, high species diversity and endemism of plants is also present in Taiwan. Five of the seven Scutellaria species (Lamiaceae) in Taiwan, for example, are endemic to the island. Hypotheses of multiple sources or in situ radiation have arisen to exp...

UNLABELLED Medicinal plants play an important role in health care. The use of medicinal plants for treatment is growing in view of cost and non-compliance of modern medicine as in case of non-communicable diseases. Plants such as Boswellia, ovalifoliolata, Cycas beddomei, Pimpinella tirupatiensis, Pterocarpus santalinus, Shorea thumbuggaia, Syzygium alternifolium, Terminalia pallida are endemic...

Native forest in Mauritius has been reduced to patchy degraded fragments and the extinction risk of constituent rare endemic plants is compounded by poor seed germination (Page & D’Argent, 1997; Safford, 1997; Nyhagen et al., 2005). Endemic fruiting plants evolved alongside a number of ecologically important large frugivores that are now extinct, such as the dodo (Raphus cucullatus L.) and two ...

Kenya, an African country with major higher plant diversity, has a corresponding diversity of plant associations, because of the wide geographic distribution, diverse climatic conditions and soil types. In this article, all vascular plants of Kenya were counted based on the completed "Flora of Tropical East Africa (FTEA)", and all families and genera were revised using recent molecular systemat...

Cliffs worldwide are known to be reservoirs of relict biodiversity. Despite the presence of harsh abiotic conditions, large endemic floras live in such environments. Primula palinuri Petagna is a rare endemic plant species, surviving on cliff sites along a few kilometres of the Tyrrhenian coast in southern Italy. This species is declared at risk of extinction due to human impact on the coastal ...

Turkey has 75% of the total number of plant species found in Europe. It is this exceptional amount of biodiversity that places a huge responsibility on Turkey, to ensure that these species are adequately protected in order to prevent them from being endangered or becoming extinct. Of particular importance are species related to the crops on which much of world agriculture depends. Many of the f...
