Question: Which is native to Western China, Petrocosmea or Onoclea?
Sentence (from "Yao Xing"): During his reign, he destroyed the rival Former Qin and proceeded to expand his hegemony over nearly all of western China, as he temporarily seized all of Western Qin's territory and forced Southern Liang, Northern Liang, Western Liáng, and Qiao Zong's Western Shu (西蜀) all to at least nominally submit to him, but late in his reign, defeats on the battlefield, particularly at the hands of the rebel general Helian Bobo (who founded Xia), and internecine struggles between his sons and nephews greatly damaged the Later Qin state, and it was destroyed soon after his death.
Relevant evidence: No
