Wuhan is a large city in the central part of China. This fig might be brought in from there, thus named after the city. It is the most popular fig variety in China. Its native name is Zhong Zi, which literally means "China Purple". In China, if you ask people about a fig called Wuhan, nobody knows what you are talking about. If you refers to China Purple, everyone understands. This fig can be found everywhere in China, so it might have developed into different strains over the years. I have seen all kinds of leaf patterns on Chinese websites, but one thing is common: the leaves have distinct teeth along the edge, as shown most prominently in the third picture of post #2.
