MATERIA MEDICA OF THE ANCIENT CHINESE. 373 
Su Sune [11th cent.]:—It is now found in Kuan and 
Shen [Shan si and Shen si, App. 158, 284], and in I chou and 
Yen chou [both in Shan tung, App. 106, 404]. The plant 
has a perennial root of a purple colour and is covered with 
many hairs (radical fibres). The leaves are like Thuja leaves 
but smaller, curved inward like the toes of a chicken. 
The plant grows from three to five inches high, and has 
neither flowers nor seeds. It is common on stones. 
Ii Sui-cHen says that this plant never dies. 
Ch., XVI, 3:—Kiian po. The figure seems to represent 
Selaginella involvens, Spg. The description in the P. 
agrees. This curious plant, of the order Lycopodiacew, is 
very common in the Peking mountains, where it grows on 
stones and rocks. It has the fronds curled in and contracted 
when dry, in which condition it is of a yellowish brown 
colour, but it expands immediately and assumes a fresh, 
green colour when put into hot water. Its common name at 
Peking is J J 3 tang tang ts‘ing, which means “it 
becomes green in hot water.” 
Tatar., Cat., 60:—Kuian po. Lycopodium hygrometricum. 
—P. Sura [141] erroneously identifies kiian po™ with Lyco- 
perdon squalmatum, which, he says, is a fungus with curved, 
compressed fronds [sic !].
