Poems and authors of cactus

Overlooking Chang 'an, Kyoto, on Gaoshanhua Mountain, these three peaks stretch into the sky without artificial cutting. The clouds in front of the emperor's temple will dissipate and the cactus will be green. Mountains and rivers are the advantages of this west gate. From here, roads and paths lead to China. Oh, pilgrim of fame, oh, man of profit, why don't you stay here and prolong your life? . (Cui Hao's "Crossing Huayin")

However, the "cactus" here refers to the cactus peak in the east of Huashan Mountain, not plants.

I have often heard of Yuquan Mountain, and there are many caves with milk caves. The fairy mouse is as white as a crow, hanging upside down on the Qingxi moon. In the middle of this stone, Yuquan keeps flowing. Genk spilled Jin Fang to moisten his bones and muscles. Clusters are always rolling green leaves, and the branches are connected. Exposed to cactus, it seems to be patting the cliff shoulder. If you don't see it at the end of the world, whose name will be passed down.

Zong Ying is a Zen master. He gave a good article. There is no salt in the mirror. You are ashamed of Xi Yanzi. Sitting in the morning, I have fun, I sing and broadcast heaven. (Li Bai's "Answering the Monk's Fu and Giving the Yuquan Mountain Cactus Tea")

The cactus here seems to be a kind of tea.
