Avoid direct translation as 'японский клематис' if the specific species (Clematis terniflora) is not intended, as 'клематис' is a genus with many species.
Do not confuse with 'ломонос' (a common Russian name for clematis), which may refer to different native species.

Common Mistakes

Mispronouncing 'clematis' with stress on the second syllable (/klɪˈmætɪs/ is incorrect). Correct is /ˈklem.ə.tɪs/.
Using 'Japanese clematis' as a general term for any clematis grown in Japan, rather than the specific species.
Misspelling as 'Japanes clematis' or 'clemantis'.
