 it over to me for a closer examination. As plants of this 

 type lately have attracted some attention but still are very 

 imperfectly known, the Swedish specimen may deserve a 

 short description. It has here been attributed to the newly 

 established genus Phyllotenia S alfeld, but this classification 

 is wholly provisional.
