Abstract
Biological peculiarities of Th ymus praecox Opiz ( Lamiaceae ) were studied in West Siberia in 2011-2018. It was determined that, when introduced to the new area, the species developed as a summer-wintergreen perennial. Th e plant passed through all the phases of seasonal development, bloomed and bore fruit regularly, retained green foliage in winter. Examination of sexual diff erentiation showed that the introduced species had only bisexual flowers. A histological study of buds’ anatomy revealed that fruit buds formed in the spring of a subsequent year.
