I'm translating a novel, set in South Africa, and I found those plants, but
I couldn't find the Italian equivalent of their names.
I recommend that you start by getting the botanical names, then inquire from an
Italian Web site. However, unless the plants have been grown in Italy, or are
known in the part of Africa that was once an Italian colony (Eritrea &
Ethiopia), they may not have Italian names. Arum denotes a huge group of
plants. You will have to be more specific about that one.

that ain't so."
