Cycas panzhihuaensis

Cycas panzhihuaensis is a rare and vulnerable species of cycad known in the wild only from Sichuan and Yunnan provinces in China. It can be seen at the South China Botanical Garden in Guangzhou and is also cultivated for horticulture, where it is often known as the Dukou sago palm.

 * Sichuan province: Ningnan County and Panzhihua [Dukou 渡口] (Baguan River and Jinsha River area)
 * Yunnan province: Huaping County and Yuanmou County. Populations in Luquan County are shrinking.
