I am having an awfully heated argument with my friend about this plant. All
about its English common name - one of these is of course Schisandra,
another is Magnola vine, but I have googled and lots of sites refer to this
plant as "Wu-wei-zi"'. This name is of course of Chinese origin (it means
"having five tastes" or something), but the question is, whether it has been
*accepted* into English language? Or is my friend right and it is solely and
purely Chinese?

Regards, B.
