Tafel 2 



Plate II. Suicession of leaves in typical Lychnis dioica (^abuve) and in L. dioica an- 

 gustifolia. The leaves of the two series are severally homologous, the first leaf at the 

 left being a "climax"- leaf (i.e. the longest leaf) of the rosette; the second leaf is from 

 the base of the stem, and the remaining leaves are from the successive nodes of one of 

 the principal axes.
