Abstract
Raimonds Cinovskis (1930–1998) devoted his entire life to plants, especially to the research of dendroflora in Latvia, as well as in the Baltic states in general, and he also participated in botanical expeditions in several places in Asia. He introduced many new names of plant taxa, described new taxa, and made new name combinations. Although the plant names he created are widely used by Latvian botanists and can also be found in the seed exchange catalogues issued by local botanic gardens, these names have never been (with some exceptions) evaluated before. This paper summarises all of the names of plant taxa introduced by R. Cinovskis. It was established that R. Cinovskis introduced more than 200 new names of plant taxa or new name combinations for plants belonging to 11 plant families — Betulaceae, Caprifoliaceae, Cupressaceae, Grossulariaceae, Juglandaceae, Pinaceae, Ranunculaceae, Rosaceae, Salicaceae, Sapindaceae, and Ulmaceae. The majority of the names of plant taxa were for plants of the rose family (Rosaceae). Critically evaluating the compliance of the names introduced by R. Cinovskis with the International Code of Nomenclature for algae, fungi, and plants, it was concluded that the majority of the names were published illegitimately.
