Representatives of the genus Epimedium L. (family Berberidaceae) are herbaceous spring-flowering perennials with medicinal and decorative significance. The collection VILAR Botanical Garden contains three species Russian Federation flora - E. colchicum (Boiss.) Trautv., koreanum Nakai, macrosepalum Stearn hybrid taxa widely used as ornamental plants х rubrum Morren, versicolor warleyense Stearn...

Apterous and alate viviparous females of Protaphis kvavadzei sp. n. on Eryngium campestre (Apiaceae) and Aphis matricariae sp. n. on Matricaria sp. (Asteraceae) from Turkey are described. The new species are differentiated from other aphids colonising these host plants and from species with similar morphology.

Species interactions are well known to affect species diversity in communities, but the effects of parasites have been less studied. Previous studies on parasitic plants have found both positive and negative effects on plant community diversity. Cuscuta howelliana is an abundant endemic parasitic plant that inhabits California vernal pools. We tested the hypothesis that C. howelliana acts as a ...

Eryngium maritimum is a coastal plant of the Apiaceae family. This species is threatened in several countries where it reaches the northern limits of its distribution area. Existing populations in the Baltic Region and Scandinavia are potentially affected by the low efficiency of its generative reproduction. We studied physiological aspects of its germination and dormancy breaking requirements ...

According to IR, 13C and 1H NMR, APT, 1D NOE, 2D heteronuclear 1H/13C HSQC and 2D DOSY experiments the main chemical constituent of high-molecular preparations from Symphytum asperum, S. caucasicum, S. officinale and Anchusa italica (Boraginaceae) was found to be caffeic acid-derived polyether, namely poly[3-(3,4-dihydroxyphenyl)glyceric acid] (PDPGA) or poly[oxy-1-carboxy-2-(3,4-dihydroxypheny...

The high-molecular water-soluble preparations from several species of two genera (Symphytum and Anchusa) of Boraginaceae family Symphytum asperum, S. caucasicum, S.officinale and Anchusa italica were isolated. According to IR, C and H NMR, APT, 1D NOE, 2D heteronuclear H/C HSQC and 2D DOSY experiments, the main chemical constituent of these preparations was found to be caffeic acid-derived poly...
