Endemic plants

Cinnamomum balansae is an endemic, rare species of tree in Vietnam, was rated level EN by IUCN, VU by the Vietnam Red Book – 2007 and classified as group IIA by Decree 32/2006/NĐ-CP. Besides its natural regeneration capacity is very limited so conservation and development for this species are facing a big challenge of seedling shortages.

Ebook "Endemism in vascular plants (Plant and vegetation, Volume 9)" is the first comprehensive analysis of the macroecology and geobotany of endemic vascular plants with case-studies and analyses from different regions in the world. Endemism is a pre-extinction phenomenon. Endemics are threatened with extinction. Due to international nature conservation policies and due to the perception of the public the concept’s importance is increasing. Endemism can result from different biological and environmental processes.

Onosma L., the largest genus of Boraginaceae, is represented by 105 species in Turkey with an endemism rate of 52%. Phytochemical studies indicate that Boraginaceae plants mainly comprise naphthoquinones with a wide range of biological activities including anticancer, antiinflammatory, wound healing, and antioxidant effects. However, few taxa of the genus Onosma have been investigated in detail for their bioactivities.

Amorphophallus albus P. Y. Liu & J. F. Chen (Araceae) is a plant species with extremely small populations (PSES P) and an important economic crop endemic to dry-hot valleys along the Jinsha River. In order to gain information for sustaining the development and conservation of A. albus, we studied the genetic diversity and population structure of this species using microsatellite markers (SSR).

Climate aridization and increased anthropogenic pressure pose a severe threat to natural vegetation, including coastal plant communities. Those located in river basins of the desert zone of Central Asia are among the most vulnerable. Of the variety of ecosystems of the Ili-Balkhash region of Kazakhstan, forests dominated by a rare relict species Populus pruinosa Schrenk are of particular concern. This species occupies a very narrow ecological niche associated with river banks of the arid zone, which makes it very vulnerable to adverse natural and anthropogenic factors.

Turkey is one of the most important temperate countries on Earth in terms of plant diversity. There is a growing interest in understanding habitat suitability and future distributions of species in the scientific world. Because climate change has impacted ecosystems with major consequences, species are shifting and declining much faster than in the past. Some global climate models used for predicting climate in the future better represent and have higher reliability for some climate types. Ferulago glareosa, which lives in Turkey, is a rare endemic plant species.

We studied the application of the neglected name Centaurea leucolepis DC., concluding, by examination of the literature and original material, that the associated taxon is C. corensis Vals. et Filig., endemic to Campania region (southern Italy) and introduced into Sardinia. The name by Candolle is legitimate and it is here lectotypified by a specimen kept at G. In addition, after field surveys and herbarium searches, we suggest that this taxon should be considered as a subspecies of C. deusta Ten.

Laggera tomentosa Sch. Bip. ex Oliv. et Hiern (Asteraceae), an endemic Ethiopian medicinal plant, is traditionally used to treat various ailments. Previously, the chemical constituents of the essential oil (EO) of its leaves and inflorescence were documented. However, no data about the chemical compositions of other parts of the EOs of the plant have been reported to date. Moreover, there are no previous biological activity reports on any parts of the EOs of this plant.
