All Rafa needs is a translator, but it must be one who is interested in
plants.
I attended a study weekend in the U.S. where several of the speakers
did not speak English. The organizers had engaged translators for
them.
The translator for the Chinese botanist was a young student who did not know
much about plants. We could understand the botanist's Latin names, but
all the student said of each plant was that it was used for medicine. Not very
useful for those of us who wanted to grow them.
The translator for the Japanese lecturer was very good - a Canadian anthropology
professor who was interested in plants, and therefore was able to make his
translation very interesting and useful. He was asked to be the translator for
the Chinese botanist's second lecture, and what an amazing difference it made.
