To this genus belongs the Mistletoe. Eound it clings many 

 a myth from old Keltic and Teutonic times. The New 

 Zealand species, however, are insignificant, and seem to have 

 been unnoticed by the Maoris. Their mode of attachment to 

 the host is quite unknown. The European mistletoe puts out 

 a radicle which terminates in an attachment disk, that 

 becomes cemented to the host. From the centre of this disk 

 is pushed out a " sinker " into the tissues of the branch below. 

 No further development takes place in the first year. 

 Subsequently, there is developed an extremely complicated 

 series of suckers, which may be compared to a rake in shape. 

 The process is very intricate, but highly interesting.
