MATERIA MEDICA OF THE ANCIENT CHINESE. 201 
About ten years ago I sent to my late friend Maximowicz 
the drug k‘wan tung hua obtained from a Peking drug-shop. 
He found that it was the flower-buds of a Tussilago, and 
observed that no species of this genus has hitherto been 
gathered in China, but an allied genus—Petasites—is repre- 
sented in Japan and China by P. japonicus, Mig. ( Tussilago 
_ petasites, Thbg.),! 
Cust. Med., 74 (122):—K‘uan tung hua exported 1885 
from Han kow 540 piculs,—p. 30 (115), from Tien tsin 
99 piculs,—p, 62 (48), from I chang 37 piculs. 
Amen. exot., 831 :—¥ & ro vulgo fuki sabuki. Petasites 
vulgaris. Caules hic inter olera recipiuntur. 
So moku, XVII, 25, 26 :—Same Chinese name, Petasites 
japonicus, Miq. 
3 Hf To wu, given in the P. asa synonym for k‘uan 
tung hua, is in Japan applied to another Composita. 
Amen. exot., 827:—Tswa [no Chinese characters]. 
Doronicum radice tuberoso, folia Petasitidis, floribus luteis 
Chrysanthemi. Caules et pediculi inter olera recipiuntur.— 
This plant, figured in the Icones Kempf. [sel. 27, 28] is the 
Tussilago japonica, L., and Tusa., Fl. jap., 318, = Senecio 
Kempferi, DC. Prod., VI, 363, = Ligularia Kampferi, 
8. & Z. Fi, jap., I, p. 77, tab. 35. Nomen japonicum 
‘swa, nomen sinicum takgo. In Stes., Icon. ined., the Chinese 
characters 3% iF are given. It flowers late in autumn and 
ma Winter. It is the Farfugium Kempferi, Benth., Fl. hongk., 
i. 
H "1 obtained specimens of tung-hua growing wild in T‘ang district, 
tupeh, whence the drug is sent to Hankow for sale, and these were iden- 
ed at Kew as Tussilago Farfara,L. This is an excellent example of the 
oy and extent of knowledge of LOUREIRO, who found out the correct 
— “cts 100 years ago.—A, HENRY,
