Hu Sanxing (Chinese: 胡三省; pinyin: Hú Sānxǐng; 1230–1302), born Hu Mansun (胡滿孫), courtesy names Shenzhi (身之), Meijian (梅澗), and Jingcan (景參), was a Chinese historian and commentator who lived during the late Song dynasty and early Yuan dynasty.
Hu was born in Ninghai (current Ninghai County of Ningbo, Zhejiang Province). He was a mid-level official under the prime minister Jia Sidao during the 1250s. After the fall of Song, he hid himself in the country, and he spent the next few years, until the end of his life, writing his influential corrections and commentaries for the Zizhi Tongjian. Hu's commentaries are considered highly valuable for readers of the work.

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
