yellow. The young leaves can be eaten. The drug from 
Huai k‘ing fu (in Ho nan) is considered the best. 
The P. [XVI, 10] notices after the ti huang a plant 
called J jij 38 hu mien mang, regarding which the Pen ts‘ao 
shi ¢ [8th cent.] says, that it grows in Ling nan [S. China, 
App. 197]. Leaves like those of the ti huang. It (the root) 
is of a sweet taste and used in medicine. 
The above descriptions of the t huang agree well with 
Rehmannia glutinosa, Libosch., a common plant in N. China. 
At Peking, where it is not cultivated, it is called ¢ huang. 
Four more species of Rehmannia are known from other parts 
of China. 
Ch., X, 8:—Ti huang, two good drawings of Rehmannia, 
one of them represents a plant with a very large fleshy 
toot. See also Kiw huang, LILI, 3. 
According to Father Crsor [Mém. cone. Chin., V, 498] 
the root of the # huang furnishes a yellow dye. The P. says 
nothing about its being employed for tinctorial purposes.
