 and that of the leaves in relation to each other is the 

 Relative Prmfoliation.

 Relative Praefoliation. 



As regards the independent praefoliation the leaves are 

 either Flat as in the Akamatsu and Momi (Abies fir ma), 

 Folded as in the Mokuren and Momiji, or Boiled as in the 

 Hasu and Warabi.

As regards the relative praefoliation, the margins of 

 contiguous leaves either touch without overlapping, as 

 the sepals of the Senninso (Clematis paniculata) and 

 Kazakuruma (G. patens), or overlap one another, as the 

 petals of the Fuji and Tsubaki. In the former case the 

 relative praefoliation is said to be Valvate, and in the 

 latter Imbricate.
