The article provides information on type specimens of 150 taxa of vascular plants from Korea, kept in the Herbarium of the Komarov Botanical Institute of the Russian Academy of Sciences. For all specimens, type category is indicated. Lectotypes for the names of Clematis brachyura Maxim., C. spectabilis Palib., Corydalis wilfordii Regel, Poa viridula Palib., Polygonum marretii H. L$\acute{e}$v., P. sagittatum L. var. hallaisanense H. L$\acute{e}$v., P. taquetii H. L$\acute{e}$v. and P. thunbergii Sieb. et Zucc. var. coreana H. L$\acute{e}$v. were designated. Type specimens examined in this article belong to the taxa described by Russian botanists V.L. Komarov, K.J. Maximovicz and I.V. Palibin, French botanist A.A.H. L$\acute{e}$veill$\acute{e}$ (some with co-author E. Vaniot) and others.

Polymerization of styrene with tributylborane in the presence of various p-quinones (2,3-dimethyl-1,4-benzoquinone, 1,4-naphthoquinone, menadione, duroquinone, 2,5-di-tert-butyl-1,4-benzoquinone) has been investigated. It was found that in spite of dual nature of p-quinone and the presence of tributylborane in the initial mixture, the semi-quinone macroradical is capable to “chain regeneration”. Neither solvent introduction nor use of a more reactive triethylborane affects this process. The insensitivity of this reaction to external conditions may be caused by the cell effect. For some p-quinones in the presence of tributylborane, the realization of reversible-deactivation radical polymerization is observed. Mechanism of the chain termination reactions was established by the MALDI-TOF technique. It consists of reversible inhibition causing the formation of active macromolecules as well as irreversible inhibition causing the formation of “dead” macromolecules. The ratio of these directions depends on the relative reactivity of p-quinone (kz/kp). The higher is kz/kp, the lower is the probability of irreversible inhibition. Polymers obtained in the presence of the tributylborane/p-quinone system can re-initiate polymerization. Post-polymers with distinct molecular weight characteristics (Đ = 1.12 – 1.19) were obtained during this synthesis. Only polystyrene macro-radicals are formed during polymerization re-initiation. This fact has been proven by ESR spectroscopy. The macroinitiator polymers isolated at the initial conversions have the same reactivity regardless of the p-quinone nature. The linear dependence of Mn with conversion, the polydispersity lessening, and the constant concentration of macro-radicals indicate realization of reversible-deactivation radical polymerization.

The genus Gueldenstaedtia Fisch. is small genus of Fabaceae that includes four species worldwide. Among these, G. monophylla Fisch and G. verna (Georgi) Boriss. are currently recognized as occurring in Mongolia. Here, we present our findings on G. verna from our recent field surveys in eastern Mongolia in 2020. Gueldenstaedtia monophylla is mostly distributed in the western region, whereas G. verna occurs in eastern Mongolia. The regional conservation status of both species was assessed as near threatened based on criterion B in the country. We provided descriptions, grid distribution maps, taxonomic notes and photographic illustrations of the two species based on our newly collected samples.
