A new documentary highlights 28 plant species native to China, Xu Fan reports.

A rare Chinese botany documentary The Journey of Chinese Plants recently debuted at the third Beijing Documentary Week, which ends on Thursday.

Consisting of 10 episodes, each 50 minutes long, the series for television and web highlights 28 plant species that are native to China, after nearly two years of filming across 27 provinces and in seven other countries, including the United States, Britain, Japan, Italy, India and Madagascar.

"China is a treasure trove of plants. We consider around 35,000 plant species to be native to China, representing approximately one-tenth of the world's total plant species," says Li Chengcai, chief director of the documentary.
