The finding of Mitrasacme indica (Loganiaceae, a new family to Russia) on the Russian far east

摘要

In the south part of Primorsky Territory, near the frontier with Korean People's Democratic Republic, the specimens of Mitrasacme indica Wight were collected. It is the first and single finding of this mainly Australian genus and South-Western Pacific Ocean species as well as the family Loganiaceae, tribe Spigelieae in Russia. The plants are found on the territory of Khasansky District on low coastal plain at the eastern foot of the Mt. Golubiny Utros (180 m). They grew on waste sandy places among wet grassland. The population of this species in Primorsky Territory is situated 600-700 km northwards of the main area of M.indica in Korea. The specimens of M.indica from Primorsky Territory are distinguished from the plants growing in japan and Korea by smaller sizes of their stems only.
