THE BALSAM-POPLAR 



20. Under the term hu Vuh (Japanese koto) M fll ("t'ung tree of 

 the Hu, Iranian Paulownia imperialist" that is, Populus balsamifera), 

 the Annals of the Former Han Dynasty mention a wild-growing tree 

 as characteristic of the flora of the Lob-nor region; for it is said to be 

 plentiful in the kingdom of San-san HP H. 1 It is self-evident from the 

 nomenclature that this was a species new to the Chinese, who discovered 

 it in their advance through Turkistan in the second century B.C., but 

 that the genus was somewhat familiar to them. The commentator 

 Mon K'an states on this occasion that the hu Vun tree resembles the 

 mulberry (Mortis alba), but has numerous crooked branches. A more 

 elaborate annotation is furnished by Yen Si-ku (a.d. 570-645), who 

 comments, "The hu Vun tree resembles the fun fll (Paulownia im- 

 perialis), but not the mulberry; hence the name hu fun is bestowed 

 upon it. This tree is punctured by insects, whereupon flows down a 

 juice, that is commonly termed hu Vun lei ffl ffl M ('hu-t'un tears'), 

 because it is said to resemble human tears. 2 When this substance 

 penetrates earth or stone, it coagulates into a solid mass, somewhat on 

 the order of rock salt, called wu-t'un kien 1o fil g (< natron of the wu-t'un 

 tree,' Sterculia platanifolia). It serves for soldering metal, and is now 

 used by all workmen." 3 



The T'un tien jil &, written by Tu Yu tt f6 between the years 

 766 and 801, says that "the country Lou & 4 among the Si 2un ffi ^L 

 produces an abundance of tamarisks Wzffl (Tamarix chinensis), hu t'un, 

 and pai ts'ao Q ^ ('white herb or grass'), 5 the latter being eaten by

1 Pliny (xn, 18, § 33) speaks of a thorny shrub in Ariana on the borders of India, 

 valuable for its tears, resembling the myrrh, but difficult of access on account of the 

 adhering thorns (Contermina Indis gens Ariana appellatur, cui spina lacrima pretiosa 

 murrae simili, difficili accessu propter aculeos adnexos). It is not known what plant 

 is to be understood by the Plinian text; but the analogy of the "tears" with the 

 above Chinese term is noteworthy.

 describing the products of Lou-Ian.

5 This is repeated from the Han Annals, which add also rushes. The "white 

 grass " is explained by Yen Si-ku as " resembling the grass yu ^ (Setaria viridis), but 

 finer and without awns; when dried, it assumes a white color, and serves as fodder 

 for cattle and horses."
