SEDUM Sp. — ^ ^ (Shih-sung), 1158. In most places 

 this is Lycopodium clavatjmi (see the article on Lycopodiu7)i)^ 

 but Faber also gives this identification. 



SELAGINELLA INVOLVENS. — 1 \^ (Chiian-po). 

 The Customs Lists, 1438, confound this with "% ^ % (Wan- 

 nien-sung); but this is properly ^ ^^ (Yii-po), or Lycopodium 

 jap07iiciim. Bretschneider says : '' This curious plant of the 

 order Lycopodiaceae, 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

 power of driving away evil spirits is also ascribed to it.

 difficult labor.
